Optimization of Tool Path for Surface Machining Based on Accuracy

Surface machining is the key technology in numerical control (NC) machining, and the planning of tool path is the basis and key of NC programming. Based on the improvement of the precision and efficiency of surface machining, this work analyzes the approximation machining error of NC machining of multi-coordinate surface. The tool step and calculation of cutting distance for tool path are discussed. The principle of tool path planning during surface NC machining programming is proposed, and the track verification is carried out with examples.
