Question

Q/ what is the system component of group technology, with the reference ?

Note : please i want the references from

(books and scientific articles) not website links,

also writing is clear.

Thanks

Answer 1

System Components of group technology

• The basic approach enables all aspects of manufacturing, from design, through estimating and planning, to production, to be rationalized. It forms the basis for the development of computer-aided procedures and flexible automation.
• Group technology is a manufacturing philosophy or principle whose basic concept is to identify and bring together related or similar parts and processes, to take advantage of the similarities which exist, during all stages of design and manufacture.
• Group Technology was invented to transfer benefits of economies of scale to job shop production during the 1960s, its underlying methodologies are still relevant for modern production, which follows the lean production paradigm.

• Group Technology is a concept that is currently attracting a lot of attention from the manufacturing community. Group Technology offers a number of ways to improve productivity in batch manufacturing. The essence of Group Technology is to capitalize on similarities in recurring tasks. Group Technology is, very simply, a philosophy to exploit similarities and achieve efficiencies grouping like problems.

• Group technology is an approach to organizing manufacture which can be applied in any industry (machining, welding, foundry, press work, forging, plastic molding, etc.) where small-batch variety production is used.

The advantages of group technology are:

1. Better lead times result in fast response and more reliable delivery.

2. Material handling is reduced considerably.

3. Robots can be easily used for material handling.

4. Better space utilisation.

5. Smaller variety of tools, jigs and fixtures.

6. Improved quality and less scrap.

7. Output is improved due to improved resource utili­sation.

8. Work in progress and finished stock levels are re­duced.

9. Simplified estimating, accounting and work man­agement.

10. Improved plant replacement decisions.

11. Improved job satisfaction, morale and communica­tion.

12. Reduced product design variety.

Disadvantages of Group Technology:

1. Additional cost of implementation of this system.
2. Rate of change in product range and mix.
3. Difficulties with out-of-cell operations.
4. Coexistence with non-cellular systems.

Uses of Group Technology:

Survey of product and use of group technology:

Group technology technique can be conveniently followed using a classification system. In any assembly, a variety of parts exist. These varieties of parts can be-segregated in three broad areas, viz.

1. Standard and proprietary parts (like nuts, bolts, screws, keys, washers, etc.)
2. Similar parts (like shafts, gears, bearings, levers, etc.)
3. Product specific parts (like gear box, bed, saddle, etc.)
