Online Education/Training Session on "Effective Industrial Engineering and Productivity Management."

I developed an online education/training session on "Effective Industrial Engineering and Productivity Management." I can present the session in one hour, one and half hour or two-hour long sessions. The sessions will be valuable when company industrial engineers and other engineers and managers attend as a group. Industrial engineers require active cooperation and participation of other engineers and managers in their studies and projects. Hence a common presentation and discussion on effectiveness will be very useful.

Jigs and Fixtures improve productivity of process, equipment and operators.

Basic Principles of Jig and Fixture Design

1. Reduction of handling time: Method of location and clamping should be such as to reduce handling time to minimum.

2. Rigidity: The jigs and fixtures have to be rigid. Cast iron which absorbs shocks more readily is recommended as body material.

3. Clearance between Jig walls and component: There should be good amount of clearance between component and body of jig to provide for variations in the dimensions of the component. Clearance is also required for chips to come out.

4. Swarf Clearance: There has to be clearance for swarf. Cored holes are provided for this purpose in bigger jigs.

5. Locating and supporting surfaces wherever possible be removable and be of hardened material.

6. Easy loading and unloading: The process of loading and unloading the component should be as easy as possible. In case of heavy components, it should be possible to slide the component into the fixture.

7. Clamping: Clamping should always be arranged directly above the points supporting the work.

8. Fool proofing: Incorporate arrangements that ensure that jig closes only when the component is inserted correctly.

9. Design for safety: Do not leave any sharp edges in the jig body.

10. Component should be ejected when the jig cover is opened.

11. Spring Locations: The number of locations on any rough component should never exceed three in any one plane.

12. Jig Base: A jig which is not bolted to machine table must be provided with four legs.

13. Accuracy and Variations: Jig design must permit only acceptable variation in the dimensions of the finished component.

14. Jig bushes: Jig bushes fixed in jig plates are used to guide drills, reamers and boring bars. They can be replaced when worn.


Locating and Principles of Location

A work piece in space which is free to move in any direction can move in 12 directions. To restrict the movement of the work piece completely it has to be restricted in all its 12 directions. Restricting the movement of the work piece in all its degrees of freedom or in some degrees of freedom is done by location in a jig or fixture.

Principles of Location

1..3:2:1 Method of location: A work piece can be positively located by means of six pins so positioned that collectively they restrict the work piece in nine of its degrees of freedom. 3 pins are in one plane, 2 in a plane perpendicular to it and one in a plan perpendicular as well as adjacent to both of the planes.

2. Points more than necessary should not be used in any plane.

3. Principle of extreme position of locating points.

4. The principle of mutually perpendicular planes.

5. Location for accuracy

6. Small locating surfaces

7. Replacement facilitation

8. Swarf clearance

Machining Cutting Tools - Industrial Engineering and Productivity Aspects

Lesson 52 of Industrial Engineering ONLINE Course

Lesson 9 of Process Industrial Engineering ONLINE Course (Module)


When Taylor started his productivity improvement studies and research, only carbon steel is the tool material. Taylor, developed high speed steel and did number of experiments to find the maximum cutting speed, feed and depth of cut combinations for various machining jobs.  This productivity improvement of machining by Taylor is the foundation for industrial engineering. Industrial engineering is engineering with productivity focus.

In the area of cutting tools, number of new materials were discovered and invented increasing the cutting speed, feed and depth of cut combinations to give very high material removal rate. Industrial engineers have to know the application of each tool materials and its best use in a machining job. They need industrial engineering knowledge base to guide them in this area of productivity improvement. They need to examine productivity aspect of each and every cutting tool element and develop ways to use the productivity potential in their process plans. Some aspects are covered in this note at the moment. They will be updated.

In area of cutting tools, there are engineering advances and developments every year. Industrial engineers have to obtain the catalogues of cutting tool manufacturers every year and have to note the capabilities of new tools. In industrial engineering there is a forward thinking which starts from the awareness of new engineering item or idea. The IE has to think over its application in the processes under his management. This is a screening process. If the idea or item is thought to be useful in the first step, the next step is to be undertaken and the process continues until a decision to use it in the process is taken. Some ideas or items will not prove feasible and they will be set aside at that stage.

Backward thinking in industrial engineering is thinking during process studies and method studies. In these studies, alternatives are identified for existing engineering elements. Industrial engineers have to remember or quickly find out from sources, the relevant alternatives. Needless to say, knowledge management in paper files, or digital files or digital knowledge management systems facilitates backward thinking in industrial engineering.

New Cutting Tool Materials


Sintered Tungsten Carbide (WC)

Sintered tungsten carbide-based hardmetals are the most common tool materials for turning, 
milling, threading, and boring using indexable inserts as well as solid round tooling.
 Characteristics of tungsten carbides include high transverse rupture strength, high fatigue 
and compressive strength, and good hot hardness. The modulus of elasticity and torsional strength are 
twice those of HSS. 

Their main drawback is that they have low chemical and thermal stability at high temperatures, which makes them unsuitable for machining steels at high cutting speeds. For nonferrous work materials, WC tools will exhibit 2–3 times the productivity and 10 times the life of HSS tools; in steels 2 times the productivity and 5 times the life.


In the United States, WC grades are often classified into eight categories denoted C1 through C8. 
The grades are broadly divided into two classes (C-1 through C-4 and C-5 through C-8). As the number increases within each class, shock resistance (toughness) decreases, hardness increases, high-temperature deformation resistance and wear-resistance increase, and carbide grain size decreases. Therefore, an increase in cutting speed or the feed load should be followed by an increase or decrease, respectively, of the classification number for the carbide grade. 

The European classification has been adopted in ISO Standard 513. This system consists of six categories designated as P-(heavily alloyed multicarbides), M-(low-alloyed multicarbides), and K-, N-, S-, and H-grades. K-grades are suitable for use on cast iron, K01 is a wear-resistant, finishing grade suitable for finish boring with no shock, while K40 is a tough grade suitable for rough milling. The N-grades are for nonferrous metals (i.e., aluminum), the S-grades are for superalloys and titanium, and the H-grades are for hard materials. K25 is for  general purpose milling. 


Straight cemented tungsten carbide and alloyed WC-Co grades

Two basic classes of carbide materials are used for cutting tools: two-phase WC-Co (straight cemented tungsten carbide; grades K01 through K40, or C1 through C4), and alloyed WC-Co grades, in which part of the WC is replaced by a solid solution of cubic carbides, such as titanium carbide (TiC), tantalum carbide (TaC), niobium carbide (NbC), or a combination of these materials (grades P01 through P50, M01 through M50, and C5 through C8). 

Straight WC-Co grades are used for workpiece materials that cause primarily abrasive tool wear and generate a short, discontinuous chip; typical materials include cast iron, high temperature alloys, high-silicon aluminum, other nonferrous alloys, and nonmetals. When used with steels, which generally yield longer continuous chips, straight WC-Co grades often fail due to crater wear on the rake face of the tool. 

Alloying also improves cratering resistance; alloyed grades containing TiC or TaC were developed for improved crater wear resistance when machining steels. Compared to straight grades, alloyed grades have increased heat resistance, compressive strength, and chemical stability. TaC alloyed grades have a higher hot hardness and better thermal shock resistance than TiC alloyed grades.

The hardness, fracture toughness, and heat resistance of carbide grades depend on the Co, TiC, and TaC contents and on the carbide grain size. Increasing the Co content decreases hot hardness and edge wear, crater wear, and thermal deformation resistance, but increases fracture toughness. 

The compressive strength is affected significantly by the Co content, and increases with Co percentage to a maximum of about 4%. The abrasive wear resistance of cemented carbides increases with increasing TiC content and decreases with increasing TaC content. Substrates with Co content less than 6% are attractive for ferrous machining at higher speeds with smaller depths-of-cut and limited interruptions.

Grain Size Differences

The WC grain size affects the tool’s hardness, toughness, and edge strength. Typical WC grades have 1.5–5 μm grain size. Fine grain WC is used for inserts and for solid drills, reamers, end mills, and other rotary tools. Coarse grain WC (2.5–6 μm) has higher fracture toughness but less wear resistance than finer grades and is used primarily for roughing. 

Since hardness increases with decreasing grain size, micrograin carbides exhibit superior resistance to crater wear, notching, and chipping in semi-roughing through finishing applications and perform well in applications where normal carbide grades tend to chip or break. 

Micrograin carbide grades are classified as fine grain (<1.3 μm), finest or submicron grain (<0.8 μm), ultra fine grain (<0.5 μm), and nano grain (<0.2 μm). 

Ultra fine grain carbide is used in special cases such as rotary tooling for high speed and/or high throughput machining applications in ferrous materials and is becoming common for high performance rotary tooling. It improves cutting edge strength and stability, preventing premature chipping and material loading and allows sharper edges because ultra-fine grain carbide is 15%–20% tougher than common carbide grades (grain size 2–3 μm with 8% Co). Nano-phase carbides are being developed for very small tools and for round high performance tools for exotic materials. An improvement of carbide performance is obtained by providing a cobalt-enriched (binder phase) layer (about 13–25 μm thick) on the surface of the tool or the tool corner. This enriched layer contains two to three times the cobalt concentrations of the bulk material. This improves the toughness of the cutting edge and resistance to chipping.

Basic guidelines for selecting carbide grades are:
 (1) use the lowest Co content and finest grain size, provided edge chipping and tool breakage do not occur; 
(2) use straight WC grades when abrasive edge wear is of concern; 
(3) use TiC grades to prevent crater wear and/or both crater and abrasive wear; 
(4) use TaC grades for heavy cuts in steels.


Cermets


Cermets are TiC-, TiN-, or TiCN-based hardmetals often described as ceramic or carbide composites. The physical properties and application range of cermets generally fall between those of WC 
and plain ceramics. Cermets are less susceptible to diffusion wear than WC and have more favorable frictional characteristics.  They can be used with sharp cutting edges in many finishing applications, which enable achievement of smooth surface finishes.

Contemporary cermets consist of TiC and TiN particles sintered with a refractory metallic binder, usually composed of nickel (Ni), cobalt (Co), tungsten (W), tantalum (Ta), or molybdenum (Mo). 

Cermets are generally available in three grades—hard, tough, and (relatively) tough but 
hard. 

Hard cermets are used in applications requiring high resistance to wear and plastic deformation, such as semi-finish and finish cutting of steels, stainless steels, free machining aluminum, and 
other nonferrous alloys (brass, zinc, and copper) and some cast irons.  

Tough cermets are also used in semi-finish and finish applications (especially milling) and in some 
rough continuous cuts in low alloy steels, stainless steels, ductile irons, and hard steels. 

The tough but hard grade is used for turning and boring and for finishing milling operations. 

In some applications, cermets provide 20%–100% longer life than coated carbides. 

The advantage of cermets over carbide is operation at much higher surface cutting speeds, with longer 
cutting edge life. 

Cermets are generally used in semi-finish to finish applications and especially high speed finishing applications. The allowable cutting speed is lower than that attainable with ceramics. 

Cermets tend to be more shock resistant than ceramics. 

Coolant is often recommended for finish turning, threading, and grooving with coated cermets. 

Micrograin cermets have much better thermal shock resistance, allowing coolant to be used in all operations.


Ceramics - Ceramic Tools


Ceramic cutting tools can be divided into four categories

1. Alumina and Alumina mixed with zirconium oxide
2. Alumina-titanium carbide composites
3. Reaction-bonded silicon nitride (Si3N4, RB)

Si3N4 is the most appropriate ceramic tool material for machining cast iron at a speed up to 1200 m/min.

 4. Silicon carbide whisker-reinforced alumina, [SiCw-Al2O3]

Polycrystalline Diamond (PCD)


PCD, the hardest of all tool materials, exhibits excellent wear resistance, holds an extremely sharp edge, generates little friction in the cut, provides high fracture strength, and has good thermal conductivity. These properties contribute to PCD tooling’s long life in conventional and high speed machining of soft, nonferrous materials (aluminum, magnesium, copper, and brass alloys), advanced composites and metal-matrix composites, superalloys, and nonmetallic materials. PCD is particularly well suited for abrasive materials (i.e., drilling and reaming metal-matrix composites) where it can provide significantly better tool life than carbide.

PCD is not usually recommended for ferrous materials due to the high solubility of diamond (carbon) in iron. However, they can be used to machine some of these materials under special conditions; for example, light milling cuts can be made in gray cast iron at speeds below 200 m/min.

PCD tooling requires a rigid machining system because PCD tools are very sensitive to vibration.

In mass production operations, the attainable tool life may be over 1 million parts (e.g., for diamond-tipped drills or PCD milling cutters machining soft aluminum alloys). However,  tooling breaks due to vibration or rough handling might occur before wear becomes significant.

Grades of PCD  vary  between 1 and 100 μm.  Grades are grouped in several categories with average grain sizes of 1–4, 5–10, and 20–50 μm. The abrasive wear resistance, thermal conductivity, and impact resistance increase with increasing grain size, but finer grained tools produce smoother machined surface finishes. A coarse-grained PCD tool may provide 50% better abrasive wear resistance than a fine-grained tool, but produce a surface with 50% higher roughness. New laser-honing methods can reduce edge radii for coarse grained PCD and produce finer finishes with these grades. Because of their increased impact and abrasive wear resistance, coarse grades are preferred for milling and for machining high-silicon aluminum alloys and metal-matrix composites.

Multimodal PCD grades (made with bimodal, trimodal, or quadimodal distributions of PCD particles) provide the high abrasion resistance of coarse-grained unimodal grade with the high toughness and superior edge sharpness of medium-size grain tools. The PCD density increases with multiple particles sizes. Multimodal grades are less prone to chipping than unimodal grades.

Laser structuring has recently been applied to flat-topped PCD inserts to produce 3-D chipbreaking grooves and similar features, which have proven effective in ductile material applications where chip control has traditionally been an issue.

PCD-tipped HSS or carbide rotary tools (e.g., reamers, end mills, drills, etc.) are available in a limited range of geometries due to difficulties in grinding complex geometries, particularly on small diameter tools. More complex geometries can be used on carbide rotary tools by sintering the diamond into slots (veins) located at the point and/or along the flutes.

Issues to be resolved include identifying the optimal cutting edge geometry for the diamond tip and the best method of pocketing the polycrystalline blank for strength and manufacturability. The methods of brazing the polycrystalline/carbide substrate tip to the main tool body have been improving steadily, but one of the major failure modes is still the detachment of the polycrystalline tip or the wear and erosion of the braze joints intersecting the cutting edge. Wear and erosion of brazed joints is avoided when the diamond is sintered into veins within the carbide tool.




BASIC TYPES OF CUTTING TOOLS
The six basic types of cutting tools are solid tools, welded or brazed tip tools, brazed head tools,
sintered tools, inserted blade tools, and indexable tools

Kennametal’s KBH10B and KBH20B grades are designed for hard turning. They are available in double-sided inserts for materials as hard as 65 HRC.  The inserts are  for “high-volume production of hardened gears, shafts, bearings, housings and other drivetrain components. A ceramic binder structure and TiN/TiAlN/TiN coating provide extreme wear resistance even at elevated cutting speeds.  A gold PVD coating makes it easier to identify when an insert needs indexing, while the numbered corners ensure that a machine operator does not inadvertently switch to a used edge. Edge preparation in a “trumpet-style” hone, is  for heavier and interrupted cuts. 

A light hone edge inserts are for continuous turning. Both inserts give extending tool life and generate surface finish values as low as 0.2 Ra.

News of New Cutting Tools - Alternative Metal Cutting Tools - Productivity Engineering Applications

Lesson 106 of Industrial Engineering ONLINE Course.

Refer to Industrial Engineering Case Studies Collection for case studies and productivity engineering applications



Industrial engineers have to first know currently available alternatives to produce to specification. Then  the best alternative to give highest productivity can be selected. Further industrial engineers have to continuously think using the basic principles of relevant engineering decision to come up with more productive alternatives.

Increasing productivity of each and every input is to be attempted by industrial engineers.

Productivity Analysis   - Productivity Engineering 

Productivity analysis provides ideas for productivity improvement using new tools or making modifications in existing tools or in the way they are being used. 

Productivity engineering needs to be undertaken to use new or modified tools and also to select new tools which are appropriate. Some examples of productivity improvement are being provided in this collection to give a direction to productivity engineering efforts related to metal cutting tools. Learn the work involved in productivity engineering by studying examples of productivity engineering.





Productivity Improvement Using Alternative  Boring Heads


Case Study 31

Productivity-boosting boring heads


Kip Hanson
April 1, 2015

Boring can be done at  higher speeds. With the growth of high-speed spindles, boring heads are spinning faster. Yet the often nonsymmetrical construction of boring heads can make them wobble and vibrate when run beyond a few thousand rpm—especially single-edge finishing heads.

BIG Kaiser Precision Tooling Inc., Hoffman Estates, Ill., provides auto-balancing heads are a must-have for these situations. They use a pinion gear to move a counterweight—as the cutting edge slides in one direction along with the cartridge (the insert holder), the weight moves opposite to it, keeping the head balanced for whatever diameter bored.

For deep-hole finishing, Smart Damper tools are to be used in conjunction with  auto-balance heads.  The Smart Damper is BIG Kaiser’s solution for chatter, a common occurrence as boring depth increases. Damping often becomes necessary at length-to-diameter ratios of 8:1 and higher.  Damping  allows for a heavier DOC and feed rate, sometimes two to three times that of an undamped boring head. Thus higher spindle speeds can be used, feed rate and depth of cut are also increased giving higher productivity. 

The Smart Damper series covers hole diameters from 1.625 " to 4 ", and up to 16 " deep.

New products for spring 2023 from  ZCC Cutting Tools

20th anniversary in 2023, the European central operations of the largest Chinese manufacturer of carbide tools is expanding its portfolio of insert milling and turning solutions to meet the needs of its target group. Now in its 20th year in Europe, the company’s newly presented products are increasingly focused on aerospace as well as die and mould making.

 

 

New YBG205H turning grade for steel and stainless steel

With the addition of the YBG205H grade to its line-up, ZCC-CT Europe now offers a highly temperature-resistant grade for turning applications primarily involving steel and stainless steel. The thin TiAlSiN PVD coating provides optimised coating stability for extremely long tool lives. At the same time, the ultra-thin layer structure guarantees optimally defined and prepared cutting edges for smooth cuts. The new YBG205H grade will initially be available as C-, D-, T- and W-shaped inserts.

 

New MU chip breaker

The MU chip breaker’s 3D-optimised chip-forming elements ensure maximum chip control, which is relevant and important for grooving as well as parting and grooving applications. This, in combination with the highly stable cutting edge achieved, among other things, thanks to harmonised and optimised macro and micro geometries, allow the MU chip breakers from ZCC Cutting Tools Europe to provide even greater flexibility in your applications. A reduction in surface contact, which is made possible by optimised chip-forming elements, results in even less wear, making MU chip breakers well suited for machining a full range of materials – from steel and stainless steel to cast iron and high-alloy materials.

 

New FME17 face milling system

The new FME17 face milling system from ZCC Cutting Tools Europe was developed specially for common roughing and finishing operations on contours and end faces with high demands in terms of surface quality. It is currently available in diameters of 50 to 400 mm. In combination with eight-edged negative inserts, the 75° milling system delivers enhanced cutting edge stability. New chip breakers for roughing, finishing and general machining operations also provide a positive cutting geometry with correspondingly lower cutting forces, while the open chip former design ensures controlled chip removal. Available in four grades for applications involving steel, stainless steel, cast iron and high-temperature-resistant materials, the newly designed SN*X inserts offer enhanced resistance to breakage along with an accompanying increase in process reliability. The SNMX120512-* inserts can also be used with two other ZCC Cutting Tools Europe milling systems (FMA17/FMP17), helping to reduce the number of variants and keep costs in check.

 

Redesigned EMP05 plunge milling system

The ultra-versatile system for grooving and plunge milling applications is able to meet the full range of requirements in machine/plant engineering and, above all else because it is well suited for ramping, in mould and die making. Extremely deep grooves are also possible at diameters ranging from 16 to 50 mm when the system is equipped with two inserts. Available as end mills or indexable heads, the tools from ZCC Cutting Tools Europe are also suitable for use in groove milling operations.

The high-performance standard grades that the ADKT* inserts for general machining applications are available in are intended for machining operations involving steel, stainless steel and cast iron.

 

New FMR06 round insert milling cutter

It guarantees maximum stability in facing operations in which solid CBN and ceramic round inserts are employed. Developed for use in die and mould making operations and in aerospace applications, the easy-to-use wedge clamping system delivers the reliability you need, even in highly demanding applications. In addition, an integrated air cooling system improves chip removal. Available in the standard 50–125 mm diameter range, two mixed ceramic, an Si3N4 ceramic, an SiAlON ceramic and a solid CBN grade are available for high removal rates and provide the process reliability required for machining hard materials, superalloys and cast iron.

 

New CSX1000 grade for turning and milling superalloys 

CSX1000 is a high-performance grade from the latest generation of SiAlON ceramic cutting materials. It combines toughness and wear resistance, making it suitable for milling operations performed, for example, on ZCC Cutting Tools Europe’s FMR06 round insert milling system and for turning applications, especially in medium machining through to roughing operations involving heat-resistant alloys. The cutting edge is optimally prepared for such applications, resulting in a significant improvement in wear resistance and very long tool lives. Additional cutting edge designs are also available for other applications.

 

New APL universal chip breaker

Thanks to its universal geometry, the APL chip breaker from ZCC Cutting Tools Europe is available for a wide variety of applications involving materials ranging from steel and stainless steel to cast iron. Plus, thanks to the available nose radii (0.4–2.0 mm), the insert sizes on offer and the three different grades that users can currently choose from, it is able to handle a whole host of milling operations. The APKT* inserts can also be used in three ZCC Cutting Tools Europe milling systems (EMP01/02 and QCH-APKT).

Productivity Analysis of Toolholders in Operation Analysis

 Operator Work Study - Machine Work Study - Interaction Study


In ILO Work Study Book, in page 349-350, it is written, "When seeking to improve the method the work study person follows two main approaches."

First, he or she tries to "push the handle down into the pump" — that is, to arrange for some of the manual elements which are being performed outside the machine-controlled time to be carried out as inside work, thus shortening the work cycle. 

Second, close attention is given to "shrinking the pump" — making the machine-controlled time as short as possible by ensuring that the machine is being used to the best advantage, to the correct speeds and feeds, and using cutting tools which are correctly ground and made of the best type of cutting steel for the sort of work in hand, so that the machine-running time is minimum with the best conditions maintained always. (This is what Taylor said, favorable circumstances.)

The first one is interaction improvement. The second is machine work improvement. The third which is not mentioned in this paragraph is operator work improvement. All three need to be done to improve machine-man work systems.


Part of Main Topic: Analysis of Items in Operation Information Sheet


Tool holders now play an important role in facilitating best cutting conditions.

Toolholders - Introduction


The design and structural properties of toolholders have a strong influence on machining cost, accuracy, and stability.

Cutting tools may either be mounted directly to the spindle/turret, or may be connected through an adapter (arbor or toolholder).  The spindle connection for a toolholder (or integral cutting tool) is the foundation that supports the cutting edge in any rotating or stationary tool machining system, and may take a variety of forms.  The toolholder is often the weakest link in the machining system, which has even limited full utilization of the potential of advanced cutting tool materials in some applications. This means some effort can be devoted to improve tool holders further.

The basic question for the analysis is what alternative toolholders are available and what cutting conditions do they facilitate?

5-Axis machine fixtures through 3D Printing

One of the biggest hurdles to spindle optimisation - the key performance indicator for any CNC machine shop - is workholding setup and changeover. Workholding fixtures, manufactured in metal,  take up to two weeks to make and delay the orders. By using Generative Design from Autodesk Fusion 360, and the speed of an HP4200 Multi Jet Fusion 3D printing machine, a bespoke workholding for a five-axis CNC machining demonstration on a Matsuura MX-850 was done.
