PRODUCTIVITY IMPROVEMENT
• Increase output while input remains same
• Decrease input while output remains same
• Increase input resulting in a very large increase in
output
• Decrease input by a very large amount with a
resultant small reduction in output
PRODUCTIVITY IMPROVEMENT TECHNIQUES
• CAD/CAM
• CIM
• ROBOTICS
• SHIGEO SHINGO PRINCIPLES
• GROUP TECHNOLOGY
• JOB ROTATION
• TQC
CAD/CAMCADA software system that uses computer graphics to assist in
the:
• Creation
• Modification
• analysis of a design
CAMUse of computer system to plan, manage and control the
operation of a manufacturing plant through either direct or indirect computer interface.
COMPUTER INTEGRATED MANUFACTURING
• CIM is the architecture for integrating the engineering, marketing, and manufacturing functions through information technologies.
ROBOTICS
• “A robot is a reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks.”
SHIGEO SHINGO PRINCIPLES
Dr. Shingo Shigeo’s teachings can be classified into the three concepts listed as follows.
• Just In Time (JIT).
• Single Minute Exchange of Dies (SMED).
• Zero Quality Control.
JIT
“JUST IN TIME”
• A philosophy of manufacturing based on planned elimination of all waste and continuous improvement of productivity.
SMED
SINGLE MINUTE EXCHANGE OF DIE
• It is one of the world class manufacturing techniques. By implementing the Set up Reduction, we can reduce waste time during machining and hence we can improve our production rate on that machine.
Zero Quality Control
Dr. Shigeo Shingo’s Zero Quality Control (ZQC) techniques make use of the following engineering principles:
100 percent inspections done at the source instead of sampling inspections
Immediate feedback from successive quality checks and self checks
GROUP TECHNOLOGY
• Group technology is a manufacturing
philosophy in which similar parts are identified
and grouped together to take advantage of their
similarities in manufacturing and design.
JOB ROTATION
Job rotation is a management technique that
assigns trainees to various jobs and departments
over a period.
Job Rotation is frequently used with new trainees
who are just entering the workforce. Trainees
gain perspective on various areas of the
organization. This provides an opportunity to
work with higher management and different
departments.
TOTAL QUALITY CONTROL
Total-Made up of whole.
Quality-Degree of excellence of a Product or service.
Management-Act,art,manner of handling controlling directing etc.
TQM is an art of Managing the whole to achieve excellence.
AUTOMATION
MANUAL OPERATED MACHINES SEMI-AUTOMATED MACHINES
AUTOMATIC MACHINES
CASE STUDY
PRODUCTIVITY WITH CONVENTIONAL MACHINING AND ADVANCED TECHNIQUES
CHALLENGE
GEX’s leaders determined they would need to improve profits 15 percent to 20 percent without adding resources in order to maintain their leading position.
