The Automatic Measurement of Complex Surface Based on ZOO-Type CMM
In general, when using the three-dimensional measuring machine to test a workpiece, the measuring route should to be planned firstly. Regarding workpieces which are formed by elementary curve or surface, there are specific software installed in the Coordinate Measuring Machine which can be used to generate the measuring route. However, when there are workpieces with no mathematic model, measuring process usually has to be done by manual operation. In this paper, we concentrate on the technical problem of measuring the blade with complex surface. After analyzing the geometric characteristics of blade, we did research on the self-study function of the Coordinate Measuring Machine, and finally put forward a method to rewrite the self-study measuring program according to geometric characteristics, which will successfully realize the automatic measurement of complex curved surface.
