1t is the first step to chec+ing appearance of the components means ho$ the component loo+s li+e.

Dhether its surface is smooth or notJ Dhether its sharp edges are chamfered or notJ 1n this step

component $elding) surface treatment and machining is also chec+ed.

2. 7I9ENSIONS0 :

1t is the most important step of the 3ualit' testing of the arious components. The dimensioning

means the chec+ing of the dimensions of the component) $hether these are correct or notJ The

The material of the component should be able to absorb the stresses produced in that component.

The material ma' be brittle) hard or tensile as per re3uirement. Hardness of the material is generall'

chec+ed b' oc+$ell hardness testing machine) poldi hardness tester and shore hardness tester.

7. P3OCESS0 :

1n this step of the 3ualit' control of the components the processes of the components are chec+ed.

8or ma+ing a certain component there are certain processes b' $hich a component should go

through. These processes are made in serial $ise and the component should follo$ these processes

in serial $ise. 1f the processes are serial $ise then component is made eactl' according to our

re3uirement. These processes can be chec+ed onl' at the production site i.e. $here the component is

manufactured. "o in case of our industr' the processes can onl' be chec+ed on the endor side

$here the component is manufactured. The processes can be drilling) punching) tapering) lathing)

heat treatment) machining etc.
