Shortly after caliper became necessary for processing 'Compatible manufacturing system'. When the company Colt used caliper, it was said that they had to readjust design basis for tolerance of fitness.
When it comes to design, how much tolerance is needed, it tells the fact that it can not be decided if it is not capable of real measurement.

Checkup for sample of good item
Is it well expressed, decision criterion is detailed?
It has to be finished identically whoever works on it.
Are the number of the parts attached and location same as sample?

Translation / English

It shows that well-timed product development that meets the demands of the present age is important. Soon afterward, vernier calipers became essential in accomplishing "the compatible production method". It is said that when they started using vernier calipers at Colt Firearms, they had to review the design criteria for fitting tolerance. The fact shows that it is impossible to determine how much tolerance is required in designing if you can't take an accurate measurement.

Comparison with fine goods sample

Are the standards of judgement clearly expressed and specific?

Make sure that any worker can achieve the same result.

Do the number of the fitting parts and their positions correspond with the sample?
