Research on the algorithm of Post-Processing with Space Tool Compensation Vector in Five-Axis CNC machine

摘要

This paper aims at A-C axis dual rotary working table five-axis CNC system, does some research about the calculating method of space tool compensation vector in five-axis CNC machine. The algorithm of post-process of five-axis CNC machine has been analyzed. The special postprocessor based on five-axis cutter location source file(CLSF) which generated from UG NX 6.0 software has been developed and applied, and there are space tool compensation vectors in the five-axis NC code. Taking blade as machined part for example, NC code machined simulation is verified in Vericut7.0 software, and space tool compensation vector for graphic simulation is analyzed. The actual calculating results indicate that the proposed method is correct and feasible.
