Group technology is based on the general principle that many problems are similar and by grouping similar problems single solution can be found to a set of problems thus saving time and efforts. This principle can be applied to any branch of engineering. The group of machines are formed so that all the components in one family can be manufactured by one machine group. These machine groups can be arranged in two ways:
a) The group lay out system
b) The group flow line system
In the first system the machines are arranged into groups in such a manner that each group can carry out all the machining operations needed for a family of components for e.g. A particular family of component requires machining operations on a lathe, a drilling machine, a milling machine and a lapping machine. These four machines grouped in two cells and located in one small area of the floor space.
In second, the machines are arranged in the sequence of production operations and usually linked by conveyor arrangement.
The Group technology is also known as “Part Family Manufacture”
This Group technology approach is used for manufacturing in automobile industry, fast food chains, doctors and dentists etc.
