摘要：
Problems of program-redundancy and speed-discontinuity can be aroused in linear interpolation, which may have an effect on machining efficiency. In order to avoid these kinds of problems, a tool path interpolation method suitable for five-axis Computer Numerical Control (CNC) machining is presented in this paper. The machining part is divided into continuous blocks and discontinuous blocks. Tool positions and tool orientations in the continuous blocks are fitted respectively. The parametric relationship between tool orientations and tool positions are analyzed, which makes real-time interpolation of tool path be possible. Results show that the method can maintain continuity of the velocity and acceleration of rotation axes and enhance machining efficiency.
