Displacement method(DM)is based on a very simple principle for straightness measurement, but there are few experimental examples. It requires three operations to measure straightness. Two of these are operations to scan the measuring piece like a reversal method, and the other is to displace the measuring piece in scanning direction. However, such a displacement becomes serious problems in practical application because of operability and accuracy. In order to solve these problems, authors propose an improved displacement method(IDM). In this method, three displacement sensors are mounted on a stage in the pattern of triangle. Instead of the displacement of measuring piece, the stage is turned through half a revolution between two scanning operations. In this paper the effectiveness of IDM was discussed theoretically and experimentally as compared with DM. According to the experimental results, both methods are about the same in measuring accuracy, and the measuring operability of IDM is much better than DM. IDM can be applied on machine tool.
