2. GROUP TECHNOLOGY
Group technology is an approach in which similar parts are identified
and grouped together in order to take advantage of the similarities in
design and production. Similarities among parts permit them to be
classified into part families.

3. Benifits of Group technology
• Standardization of tooling, fixtures, and setups is encouraged
• Material handling is reduced
• Parts are moved within a machine cell rather than entire factory
• Process planning and production scheduling are simplified

4. Over view of group technology
• Parts in the medium production quantity range are usually made in
batches
• Disadvantages of batch production:
• Downtime for changeovers
• High inventory carrying costs

5. Group technology Defined
• An approach to manufacturing in which similar parts are identified
and grouped together in order to take advantage of their similarities
in design and production
• Similarities among parts permit them to be classified into part
families
• In each part family, processing steps are similar

6. Advantages of group technology
• Better lead times result in fast response and more reliable delivery.
• Material handling is reduced considerably.
• Robots can be easily used for material handling.
• Better space utilisation.

7. Ways to identify part families
• Visual inspection – using best judgment to group parts into
appropriate families, based on the parts or photos of the parts
• Production flow analysis using information contained on route
sheets to classify parts
• Parts classification and coding – identifying similarities and
differences among parts and relating them by means of a coding
scheme
