| Abstract: | This paper classifies the five coordinate CNC machine tools according to the structure,analyses the non-linear error in the movement of to the axis of rotation and the straight axis.In view of the existing two-dimensional cutting tool compensation principle,the paper derives the kinematics transform algorithm tool radius compensation formula of three-dimensional space,and the results have been carried out to verify the algorithm formula error range,which better realizes the function,and provides a new means for the study of space tool radius compensation technology. |
