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

  1. 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
