Measurement methods in precision parts machining and milling

The classification and application of measurement methods in precision parts machining and milling: There are many types of measurement methods, including direct measurement, indirect measurement, absolute measurement, relative measurement, contact measurement, non-contact measurement, comprehensive measurement, single measurement, active measurement, passive measurement, static measurement, dynamic measurement, and other measurement methods.

The application of measurement technology in the field of precision parts processing should clarify the definition and application scope of various measurement methods. Dynamic measurement refers to the method of measuring the relative motion between the measuring head and the measured object during the continuous movement of the measured object. For example, using an indicator and a indexing head to measure the rise of the disc cam is considered dynamic measurement. Comprehensive measurement refers to a measurement method in which various parameters related to the measured object are combined into a comprehensive parameter for measurement. If a rectangular spline formed by milling is measured using a comprehensive environment, it is considered a comprehensive measurement when considering the parameters of symmetry and equal division.
