Technology of machine tools. Supplement 1. Testing of accuracy of NC machine tools
The state of the art of accuracy testing, a concept, basic explanations, definitions, methods, and a list of tests are presented here as a general proposal for a standard test that corresponds to the present state of the art of metrology of numerically controlled machine tools. The three main basic features of this system are: it is a non-machining system of tests which could be called tracing of a universal master part; it is an essentially non-statistical test which assumes that the individual sources of errors and their motions can be, to a reasonable extent, isolated and systematically combined; andmore »
