Referred to dimensional accuracy, you have to specify the machining tolerance for each dimension.
If a part’s dimensions, you produce, that are out of machining tolerances,
The parts will be unusable due to the main features and functions are not according to design idea.
There are many tolerances standards, for example, general tolerance standard, shaft tolerance standard, hole tolerance standard, ball tolerance standard, bearing tolerance standard, bushing tolerance standard, thread tolerance standard, etc
An experienced worker is very important for keeping tolerance.
When he operated the machine to do the machining process,
He has to keep the part specified tolerance and machine tolerance in the heart.
As long as he forgets one of the tolerances,
He cannot program the correct data in the machine,
All the parts will be finished in the wrong dimensions.
Without inspection will also cause a serious accident.
You have to do first article inspection and randomly inspection per 30 minutes,
Otherwise, all the parts are incorrect from the first article to the end.
Even if you do the first article inspection and randomly inspection per 30 minutes during production,
It still has the possibility to c&c machining wrong dimensions,
So the 100% fully final inspection is necessary very much.
The final inspection will check all the dimensions and inspect the wrong parts out.
It will make sure all the dimensions for all the parts are correct when your customer received them.
