INSPECTION

 

INSPECTION

 

 

Inspection gives the measurement of the quality of the product or its utility in terms of the prescribed standards .in tool making the quality of each part of tool is reflected on the quality of the component .the quality must be specified in terms of strength, surface texture and dimensional accuracy.

 

  Inspection of the core & cavity should be thoroughly done after the final machining because any slight dimensional variations will affect the accuracy of the product.

 

OBJECTIVES OF THE INSPECTION:

1)    Inspection traces defects in raw materials and flows in process.

2)    It reduces further work on semi finished items thereby avoiding further wastage of time & recovery.

3)    It improves the quality of the product.

 

TYPES OF INSPECTION:

1)FLOOR INSPECTION :

Inspection taking place in the shop floor while the work is under progress on the machines .

 

2) CENTRALIZED INSPECTION:

          This kind of inspection is carried in a separate room where high accuracy measuring and comparing devices are available all the items are brought here only for inspection .the above two types are incorporated for this tool

 

Normally in inspection we used measuring instruments like:

 

1)    Vernier

2)    Micrometer

3)    Bore dial gauge

4)    Dials

5)    Trimos

6)    Profile projector
