Abstract

FSTP (Fine Sequential-Three-Points) a new method for on-line measurement of the straightness of precision machine tools and machined workpiece is proposed in this paper. Because the sampling interval of the STP (Sequential-Two-Points) method must be equal to the distance between two adjacent sensors the sampling points can not be too close to each other. FSTP uses three sensors and chooses suitable distances between every two adjacent sensors we can obtain smaller sampling interval than before The improved algorithm of the FSTP and its flowchart are also presented in this paper. The results of computer simulation and on-line measurement experiment on a precision lathe are discussed. It can be shown that FSTP is feasible and efficient.
