Question

Difference between selective assembly and interchangable assembly

Answer 1

Interchangeability -When one component get assembled with the other one while both are selected randomly and also satisfies the functionality of that assembly.This is known as interchangeability.

Due to this assembling cost decreases,production rate increases.

Selective Assembly- There are cases in which accuracy and uniformity is the prime importance this all the parts produced are graded into groups in the range of dimensions which are within the tolerance limits.

Like we need a assembly which requires certain amount of clearance in that like 16 mm then we will group up the component in such a way that the clearance remain same as 16 mm and also the functionality of the assembly don’t get affected.
