To ensure the machining accuracy, the original numerical control program should be compensated if the cutter is worn out due to machining. The lower-hand controller has the basic G code function to obtain the compensated cutter location for planar contour machining. However, the advanced controller with cutter compensation vector function should be employed in order to process the three dimensional compensated tool path. The purpose of this thesis is to establish the multi-axis cutter compensation algorithm and develop the window’s interface of the universal postprocessor that can convert various formats of cutter location file into the associated multi-axis numerical control program. Through the verification by the solid cutting simulation software, it confirms the effectiveness of the proposed cutter compensation vector algorithm.
