Abstract: Aiming at the five axis stone cutting machine tool′s saw blade installation center point and machine tool control point existed bias and blade itself size resulting from the problem of cutting, the spatial pose relations of cutting point relative to the control point were analyzed, and the various working conditions of processing line primitives were carried on the detailed research. A kind of offset compensation algorithm based on the 3 S of open system (ServoWorks S 140M) was put forward and the contact between the tool path and numerical control path was established. The correctness of the algorithm was verified by system simulation function, and through the actual processing test. Research results show that the processing of parts meet the requirement of processing technology and precision, and improves the machining efficiency and accuracy, reduces the production cost.

 

Key words: five axis stone cutting machine; offset compensation; NC machining; blade overcut
