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).
