Influence of Main Factors in Industry Measurement on Measure Accuracy

In the process of machining, it is very important to measure the machining spare parts accurately. It is very necessary to analyze every element that influences the measure results completely, induding the changing temperature, the size of measure force, the contact area of measure, measure principle, etc. The paper analyses the effects of measure accuracy on them and points out the methods of decreasing measure error to get qualified products in practice.
