Operation Analysis
Operation Purpose
2-unnecessary operation
1-most important point
3-combine and eliminate and improve operation
Part Design
1-. Reduce the number of parts by simplifying the design
2-Reduce the number of operations and the length of travel in manufacturing
3-Utilize a better material
4-Liberalize tolerances and rely on key operations for accuracy
5- Design for manufacturability and assembly, and transportation
Tolerance and Specifications
2-Lot-by-lot inspection
1-Spot inspection
3-A 100 percent inspection
Materials
- Finding materials that are easier to process.
2-Finding a less expensive and lighter material
3-Using materials more economically.
4-Using salvage materials
5-Using supplies and tools more economically
6-Finding the best vendor from the standpoint of price and vendor stocking.
7-Standardizing materials
MANUFACTURE SEQUENCE AND PROCESS
1-Rearranging the operations
2-Mechanizing manual operations
3-Utilizing more efficient facilities on mechanical operations
4-Operating mechanical facilities more efficiently
5-Manufacturing near the net shape
6-Using robots
6 SETUP AND TOOLS
1-REDUCE SETUP TIME Just-in-time (JIT) techniques
2-UTILIZE THE FULL CAPACITY OF THE MACHINE
3-INTRODUCE MORE EFFICIENT TOOLING
Material handling ( motion, time, place, quantity, and space )
2-Material handling must ensure that parts
3- Material handling must ensure that materials are delivered to the correct place.
4- Material handling must ensure that materials are delivered at each location without damage and in the proper quantity
5- Material handling must consider storage space, both temporary and dormant
1-Material handling ensures that no production process or customer is hampered by either the early or late arrival of materials, since each operation requires materials and supplies at a particular time
PLANT LAYOUT
to develop a production system that permits the manufacture of the desired number of products with the desired quality at the least cost.
Work Design
1- product or straight-line layouts
2-process or functional layouts
