GROUP TECHNOLOGY IS A MANUFACTURING
TECHNIQUE AND PHILOSOPHY TO INCREASE PRODUCTION EFFICIENCY BY EXPLOITING THE “UNDERLYING SAMENESS” OF COMPONENT
SHAPE, DIMENSIONS, PROCESS ROUTE, ETC.
Group Technology is the realization that many problems are similar, and that by grouping similar problems, a single solution can be found to a set of problems thus saving time and effort. (Solaja 73)
First book formalize the concept:
Mitrofanov,S.P. 1958, "The Scientific Principles of Group Technology"
Why Group Technology?
Average lot size decreasing
Part variety increasing
Increased variety of materials
With diverse properties
Requirements for closer
tolerances
Production Family
Don’t “redesign the wheel”
Automated process planning
Database to drive the
automated factory
Other Benefits Of Group Technology
Easier to justify automation
Standardization in design
Data retrieval
Easier, more standardized process plans
Increases in quality
Process Planning
“Process planning” is that function within a manufacturing
Facility that establishes which machining processes and
Parameters are to be used (as well as those machines capable
Of performing these processes) to convert (machine) a piece
Part from its initial form to a final form predetermined
(usually by a design engineer) from an engineering drawing.
(I.E. The preparation of the detailed work instructions to
Produce a part)
