2.1.2 Production tolerancing - Feasibility

Halevi gave the example of set up with fixture repeatability of 0.1 mm and the machine accuracy of 0.02 mm. When the counterbore is made this machine and fixture, the length of the internal minor diameter will come 20 + or - 0.04.  It is acceptable because the required dimension is  20 + or - 0.1 mm.

The total length of the work piece is 70 mm, minor bore is 20 mm and counter bore length is 30 mm. So the length of the uncut portion is 20 mm and with this present errors it will come out to be 20 + or - 0.14. Acceptable because required dimension is 20 + or - 0.15.

But if machine accuracy is 0.03 mm, the resulting dimension tolerance will be 20 + or - 0.16. Not acceptable. Hence it is important to know the error quantities and see whether the machine and accessories in combination can produce the part to the specification or not.





2.2 Tolerances in forming operations


Halevi has given the example of a die working on a sheet metal blank.  He says errors or tolerances achieved are of three types.

1. Tool dependent dimensions.
2. non-tool-dependent and
3. non-tool dependent dimensions in the direction of the closing the tool (travel of the punch).

Machine accuracy is estimated by type three errors. Improvement of machine accuracy and jigs and fixtures will minimize type 2 errors. Tool accuracy has to be improved for type 1 errors.

Effective Industrial Engineering - Some Thoughts

 

Effective industrial engineering has to satisfy management about the contribution it made to the organization.

The prime contribution of IE has to be cost reduction through productivity improvement.

Productivity improvement is achieved through time reduction of capital assets and human resources and usage reduction of consumable items.

Reduction of machine time and man time have to be made through time studies. Time study was developed by F.W. Taylor to do this task. The purpose of time study is to measure the time taken being taken currently  by each element of the task and study each element to find opportunities for time reduction. The time study includes time measurement (or work measurement) and analysis for drivers of time at element level.

If the Time study is taken as  the highest level task, it will have many lower level studies.

Method study

Motion study

The  Career of the Industrial Engineer - Key Success Factors

https://nraoiekc.blogspot.com/2012/02/role-and-career-of-industrial-engineer.html



Key Success Factors


Be Flexible, but Focused. In whatever role industrial engineers play, they should strive to maintain a focus on value-added work.

Apply Industrial Engineering Concepts to Real-World Problems.

Understand the “Big Picture”—How Change Initiatives Impact the Overall Organization. System thinking is a skill that every industrial engineer should possess. Understanding how a change can impact an organization is essential in truly having a positive impact on the bottom line. It is easy to perform a process improvement on a subsystem, but understanding and conveying how it benefits the whole organization is what’s really important.

Understand and Analyze the Current Processes Accurately. To understand current processes an industrial engineer must live the day-to-day reality of the shop floor. (*To analyze accurately, first monitor new knowledge continuously. Collect catalogues and brochures related to all elements of all resources being used in your organization.)   

Manage Change. People manage all processes. If the people affected by the changes are not convinced of the solution, there are many ways in which they can contribute to its failure (IEs are the change agents. They evaluate the usefulness of all new commercial offerings related to various elements of resources being used in their organization).  

Follow Through on Implementation.  The goal of an industrial engineer is to create value. It is up to the industrial engineer to ensure that a measurement or tracking system is put into place, following a project implementation. Benefits as well as project costs should be tracked to the bottom line.

Be Creative. The ability to see current reality and generate new ideas is what brings the most value to any changing organization. (Creativity is combining the problem with an idea around in a novel way to solve the problem. Creativity comes out of knowledge of many possible solution ideas, the awareness of the problem to be solved and a thinking that tries to integrate the problem with the possible ideas. Creative people go on discussing the issue with many persons individually or in groups, read a lot, search a lot and think a lot.)

Communicate Clearly. To put ideas into practice, an industrial engineer must also possess excellent verbal and written communication skills. Most of the process improvements recommended by industrial engineers involve techniques or technologies that can be complex. These solutions could have a sizable impact on the business but may require significant investments. The ability to present recommendations to decision makers in a way that they can readily comprehend requires that industrial engineers work on creating clarity.

Lack of Appreciation for the Discipline. Industrial engineering is a discipline that needs to be continually sold. Industrial engineers have been grappling with the profession’s image for the last 50 years as evidenced by letters to the editor in the first issue of the Journal of Industrial Engineering in June 1949 about the necessity of selling industrial engineering.

Failure to Align with Key Business Challenges. Whether the business strategy involves growth or cost containment, industrial engineers need to position themselves to contribute the greatest value.

Failure to Evolve. industrial engineers have the responsibility of marketing themselves. Those who do a good job of this are likely to reap the benefits of new opportunities that appear on the landscape before other so-called experts are called in.


Important Key Success Factors can be arranged in a sequence.

Understand and Analyze  the Current Processes Accurately.
(Understand [Observe, Document and Study] and Analyze [Up-to-date Engineering Knowledge])
Be Creative.
Communicate Clearly.
Manage Change. 
Follow Through on Implementation.

This can also be expressed as:

Productivity Science - Productivity Engineering - Productivity Management


Productivity Science - Indicates the direction in which productivity will increase. It also indicates variables which are to be modified appropriately to get increase in productivity.

Productivity Engineering - Industrial engineers have to do primarily modifications in engineering elements of operations and processes. Then they have to redesign the work place layout and motion patterns of the operators to operate the machines and tools and to provide material inputs. As part of productivity engineering, industrial engineers have to develop engineering concepts and detailed engineering. Detailed engineering can be done by IE department personnel, or other engineering departments within the company or external engineering consultants.

The following activities are part of productivity engineering.

Understand and Analyze  the Current Processes Accurately.
(Understand [Observe, Document and Study] and Analyze [Up-to-date Engineering Knowledge])
Be Creative (in developing solutions). 

Productivity Management: Industrial engineering work needs to be managed like any other industrial or business activity.

Communicate Clearly.
Manage Change. 
Follow Through on Implementation.

The above three activities are part of productivity management task of industrial engineers.

One AI Summary on Effective Industrial Engineering


Effective Industrial Engineering focuses on configuring and optimizing complex processes, systems, and organizations by integrating principles from various disciplines to improve efficiency, productivity, and quality. This involves analyzing and designing systems, streamlining workflows, reducing costs, and enhancing service quality within various industries.  Configuring a systems involves specifying and integrating many components. Configuring is an engineering task. Optimization determines the values of the operating variables of each of these components. Normally each component has a range of operating values.

Key aspects of effective industrial engineering include:


Science based selection of system/process resources

Systems Thinking:

Viewing processes as interconnected systems of components to identify bottlenecks and areas for improvement. 

Data-Driven Decision Making:

Developing shop floor operating data and studying and analyzing the data utilizing various techniques including charts, graphs, advanced statistical analysis, operations research, and simulation modeling to make informed decisions about process optimization. 

Integration of People, Materials, Information, Equipment, and Energy:

Ensuring that all elements of a system are appropriately selected based on system requirement and integrating their work to make them work  efficiently to achieve optimal performance. 

Continuous Improvement:

Implementing strategies to constantly streamline workflows, reduce costs, and improve overall performance. 

Adaptability and Innovation:

Keeping up with the latest technologies and methodologies to address evolving challenges and opportunities. 

In essence, effective industrial engineering is about:

Making things work better: Improving the efficiency and effectiveness of processes and systems.

Making things work smarter: Utilizing data and analytical tools to make informed decisions and optimize performance.

Making things work together: Ensuring that all components of a system are appropriate and integrated and working towards a common goal.

Making things work sustainably: Optimizing resource utilization and minimizing environmental impact ( a new focus of businesses that IE has to satisfy.)

Sumanth's total productivity model


https://books.google.co.in/books?id=mLAv09ocvTsC&pg=PA5#v=onepage&q&f=false


‘Productivity’  is the standard that indicates measures how efficiently the material, the labor, the capital and the energy can be utilized. Analysis and measurement of ‘Productivity’ can help to know the areas for taking corrective actions towards planning of business firm. 

Productivity is known as the relationship between output and all employed inputs measured in real terms. It refers to a comparison between what comes out of production and what goes into production that is the arithmetical ratio between the amount produced and the amount of all resources used in terms of manufacture. 

It may be measured for manufacturing organizations or their departments for which separate records are maintained.

The success of an industrial organization is determined by the level of efficiency in reducing cost and providing consumer services. Analysis and Measurement of Productivity can help to find out the areas where the corrective steps will have been taken in the way of planning of business firm. 

TOTAL PRODUCTIVITY MODEL  

Total Productivity Model developed by David J. Sumanth in 1979 considered 5 items as inputs. 

These are Human, Material, Capital, Energy and other expenses. 

This model can be applied in any manufacturing or service organization. 

Total Productivity= Total Tangible Output÷ Total Tangible Input. 

 Total tangible output= Value of finished units produced + partial units produced + Dividends from securities + Interests from bonds +Other incomes. 

 Total tangible inputs= Value of human inputs+ capital inputs+ materials purchased+ energy inputs + other expenses (taxes, transport, office expenses etc.)

Sumanth’s provided a structure for finding productivity at product level and summing product level productivities to total firm level productivity. 

The model also has the structure for finding partial productivities at the product level and aggregating them to product level productivities. 

Total Productivity= Total Tangible Output÷ Total Tangible Input

 = O1+O2+O3+O4+O5 / H+M+FC+WC+E+X 

Where,

O1 is value of finished units of output.

O2 value of partially completed units of output ,

O3 dividend income, 

O4 interest income ,

O5 other income. 

H human input, M material input , FC fixed capital input , WC working capital input, E energy input , and x other expense.

A Case Study

Adapted from Edosomwan, J. A and David J. Sumanth. (1996). Productivity Measurement Guide: A Practical Approach for Productivity Measurement in Organizations. New York: McGraw-Hill, Inc. (pp. 179-198)

Human partial productivity index

Employees       Measure                     January              October

Workers

Hourly paid      Units/$                       17.88                  24.14

                          P.P.I                             1.00                     1.35

Salaried             Units/$                         0.366                  0.354

                          P.P.I                             1.00                     0.967

Professionals

Hourly paid       Units/$                         2.438                   3.155     

                          P.P.I                             1.00                      1.294


The calculation procedure used:  Divide the units produced in the month by expenses paid to a category of human resource. This gives  Units/$. Then calculate index  with the first month as the base year.  

Comments made on various tables by the authors. (Tables for all resources will be added)

Human Productivity 
The human partial productivity index showed a trend that followed the output curve very closely. 
Two major areas of input in this category (salaried workers and salaried professionals) had not changed significantly during the periods.
The human partial productivity index for hourly  paid professionals did show very significant gains during the last several measurement periods due to decreases in input. 


Material Productivity 
The index showed a steady decline through the first seven measurement periods, and then, showed a dramatic improvement in productivity for the final periods. This was apparently caused by the way in 
which purchases of materials from source #1 was planned. These were planned at the beginning of the year, based on a then current forecast for total productivity demand. 
Through the year, as demand fell short of the forecast, the appropriate action would have been to curtail purchases of materials from all sources. Contracts that were in place between systems manufacturing and source #1, however contained a clause that froze the level of purchases for several periods. For this reason, material productivity declined until the orders could be reset to lower levels to more accurately 
reflect the lower demand for the product. 

Capital Productivity 
The working capital partial productivity was by far the major ingredient for capital productivity and represented a major input for total productivity. 
The index showed stable or improved productivity through the first six periods, but a dramatic drop in productivity was evident in the final periods. 
This, again, relates back to the problems with the controls on material inputs and the resulting increasing of material inventory until the inputs could be reduced. During the final four periods, a slight improvement was seen and this could be expected to continue, as this measurement will follow the trend of the material productivity index, lagging by several periods. The occupancy and depreciation productivity measurements followed the same basic trend as the output since they had a small degree of variance and output had a large variance. 

Other Expense Productivity 
This category of partial productivity included many diverse expense type inputs. It was apparent, that for certain items  partial productivity improved. For example, the travel and professional fees partial productivity improved during the last several periods primarily due to management attention. 
However, the stationery, telephone and education partial productivity measurements did not show any 
improvements.  

Total Productivity 
The total productivity index followed the trend of the capital partial productivity most closely. This is due to the large percentage of input the capital productivity represents, most of this input being in the form of working capital. The total productivity index followed very closely, the output level of the product. That is the productivity index showed decline when output is below the base period output and the index shows improvements when the output is above the base period level.

The Definition of TPM

The Spread of TPM in Japan

How do TPM and TQC Differ?


The Basic Concepts of TPM

1. Maximizing Overall Equipment Effectiveness

2. Autonomous Maintenance
In factory automation, production workers do not have to operate machines themselves. These operators asked to oversee machines can do inspection of the automatic machines every day or week as per a plan and do routine maintenance. Specialist maintenance persons can act as equipment doctors, who periodically do expert diagnostic checks and do the required maintenance.

3. Small Group Activities in Maintenance
Similar to quality circles, zero defect movement groups and Jishu Kanri.

‘Jishu Kanri’ activities in the Japanese steel industry Small group activities being promoted by the industry as a whole
HIDEO SUGISAWA &KAZUO HIROSE
International Journal of Production Research, Volume 15, 1977 - Issue 6, Pages 523-538

The group activities called ‘ Jishu Kanri ’ by foremen and workers in the forefront of production has been actively promoted in the Japanese Steel Industry by establishing a committee for ’ Jishu Kanri’ activities in the Japan Iron and Steel Federation, with the positive cooperation of its member companies. Nearly 8 years have elapsed since the establishment of this committee, and during this period the ability and skill of the group leaders and members in managing group activities and their awareness of problems and solutions have been greatly improved, thereby contributing much to the improvement of quality, attainment of production targets, reduction in the production costs, and improvement of safety.
https://www.tandfonline.com/doi/abs/10.1080/00207547708943147?journalCode=tprs20

The Japan Iron & Steel Federation adopted the name "Jishu-Kanri GK) Activities" to generalize the uniqueness of small group activities in this industry. JK activities are defined as "continuous group activities in which individual workers voluntarily organize small groups, select leaders from among themselves, hold discussions on an equal footing, and with their leaders as the nuclei, take up problems at the workshop, set goals for the solution of the problems, and make efforts to achieve the goals with participation by everyone".

Workers' voluntary problem solving activities cover a wide range such as product quality enhancement, efficiency improvement, cost reduction, promoting safety at the workshop, and others. In 1983, ensuring work safety was the top of activity (27.4%). About 90% of the activities in 1993 related to four areas: 
efficiency improvement (30.8%), cost reduction (24.6%), ensuring work safety (19.6%) and product quality enhancement (14.6%).

Hoshin Kanri

Hoshin means direction and Kanri means management in Japanese.



Hoshin Kanri 7 steps

Vision
The company's leadership develops a strong vision answering the question “Why does the company exist?”.

Objectives
The leadership team defines key objectives or also a mission. If achieved, they will create a competitive edge for the company. These are major objectives usually requiring every person's effort in the company, not monthly or quarterly objectives.

Annual Goals
The leadership team, along with the senior management, breaks down the objectives into annual goals.

Goal Setting for Various Levels and Departments
Once the annual goals are crafted, they need to be “deployed” across all levels of the organization. This is the process of “goal-setting,” which starts at the top and is propagated to each employee.

Implement Annual Objectives
With the next step, the real execution starts. This step goes hand in hand with the next two.

Monthly Review
The monthly reviews make sure that the plan is being executed according to the plan.

Annual Review
At the end of the year, there is an annual review, which validates the end result that has been achieved.

WHAT IS TPM?

TPM (Total Productive Maintenance) is a holistic approach to equipment maintenance that strives to achieve effectiveness and efficiency in the use of machines by maximizing availability and by maximizing quality output from each machine hour.

The objectives or aims of TPM are:

No Accidents
No Breakdowns
No Small Stops or Slow Running
No Defects



TPM emphasizes proactive and preventative maintenance to maximize the operational effectiveness and  efficiency of equipment. In focusing on productive availability and use of machines, it places  a strong emphasis on involving operators to help maintain their equipment.

The implementation of a TPM program creates a shared responsibility for equipment that encourages greater involvement by plant floor workers in regular cleaning, lubrication and other routine machine upkeep activities. Operators also inform machine condition frequently so that maintenance can be undertaken in timely manner. TPM became effective in many companies in improving productivity (increasing up time, reducing cycle times, and eliminating defects).

8 Pillars of TPM

Autonomous Maintenance

Places responsibility for routine maintenance, such as cleaning, lubricating, and inspection, in the hands of operators.
Gives operators greater “ownership” of their equipment.
Increases operators’ knowledge of their equipment.
Ensures equipment is well-cleaned and lubricated.
Identifies emergent issues before they become failures.
Frees maintenance personnel for higher-level tasks.

Planned Maintenance

Schedules maintenance tasks based on predicted and/or measured failure rates.
Significantly reduces instances of unplanned stop time.
Enables most maintenance to be planned for times when equipment is not scheduled for production.
Reduces inventory through better control of wear-prone and failure-prone parts.

Quality Maintenance

Design error detection and prevention into production processes. Apply Root Cause Analysis to eliminate recurring sources of quality defects.
Specifically targets quality issues with improvement projects focused on removing root sources of defects.
Reduces number of defects.
Reduces cost by catching defects early (it is expensive and unreliable to find defects through inspection).


Focused Improvement

Have small groups of employees work together proactively to achieve regular, incremental improvements in equipment operation.
Recurring problems are identified and resolved by cross-functional teams.
Combines the collective talents of a company to create an engine for continuous improvement.


Early Equipment Management

Directs practical knowledge and understanding of manufacturing equipment gained through TPM towards improving the design of new equipment.
New equipment reaches planned performance levels much faster due to fewer startup issues.
Maintenance is simpler and more robust due to practical review and employee involvement prior to installation.


Training and Education

Fill in knowledge gaps necessary to achieve TPM goals. Applies to operators, maintenance personnel and managers.
Operators develop skills to routinely maintain equipment and identify emerging problems.
Maintenance personnel learn techniques for proactive and preventative maintenance.
Managers are trained on TPM principles as well as on employee coaching and development.


Safety, Health, Environment

Maintain a safe and healthy working environment.
Eliminates potential health and safety risks, resulting in a safer workplace.
Specifically targets the goal of an accident-free workplace.

TPM in Administration

Apply TPM techniques to administrative functions.
Extends TPM benefits beyond the plant floor by addressing waste in administrative functions.
Supports production through improved administrative operations (e.g. order processing, procurement, and scheduling).

Six Big Losses


Unplanned Stops Availability Loss
Tooling Failure, Unplanned Maintenance, Overheated Bearing, Motor Failure There is flexibility on where to set the threshold between an Unplanned Stop (Availability Loss) and a Small Stop (Performance Loss).

Setup and Adjustments Availability Loss
Setup/Changeover, Material Shortage, Operator Shortage, Major Adjustment, Warm-Up Time This loss is often addressed through setup time reduction programs such as SMED (Single-Minute Exchange of Die).

Small Stops Performance Loss
Component Jam, Minor Adjustment, Sensor Blocked, Delivery Blocked, Cleaning/Checking Typically only includes stops that are less than five minutes and that do not require maintenance personnel.

Slow Running Performance Loss
Incorrect Setting, Equipment Wear, Alignment Problem Anything that keeps the equipment from running at its theoretical maximum speed.

Production Defects Quality Loss
Scrap, Rework Rejects during steady-state production.

Reduced Yield Quality Loss
Scrap, Rework Rejects during warm-up, startup or other early production.

Systematic Industrial Maintenance to Boost the Quality Management Programs

Adnan Bakri, Mohd Al-Fatihhi Mohd Szali Januddi
Springer Nature, 04-Jun-2020 - Technology & Engineering - 78 pages

This book discusses the main quality management (QM) programs and their possible integration into systematic industrial maintenance (SIM). Unlike traditional engineering maintenance books, it not only explains the theory but also provides practical examples of the integration of QM and SIM programs. It also includes reference sources, making it useful for readers wanting to explore specific areas in more depth.
Chapter 1 introduces various aspects of the main quality management (QM) programs, including total quality management (TQM), just-in-time (JIT) and lean manufacturing (Lean). Subsequently, it examines the relation of quality and maintenance. Chapter 2 reviews the concepts of systematic industrial maintenance (SIM) and the application of quality control (QC) tools. Chapter 3 offers an overview, historical perspective and trends in industrial maintenance techniques. Chapters 4, 5, 6, 7, 8 and 9 focus on topics related to schedule-based maintenance, condition-based maintenance, reliability-based maintenance, computerized-based maintenance, risk-based maintenance and total productive maintenance. Covering the theory of each of these types of SIM, the chapters also explain their real-world application in QM and highlight their merits and weaknesses in the context of supporting QM.
