Optimization of cutting parameters based on surface partitioning

Abstract

With the rapid development of science and technology, five-axis CNC machine tools are widely used in the field of complex surface parts processing and manufacturing, so the part geometry model of the complex surface becomes more and more complex. Most traditional machining methods use fixed cutting parameters to calculate and generate five-axis machining toolpaths. If the fixed cutting parameters are used to generate the 5-axis machining toolpaths, the optimal cutting condition will not be obtained in some parts, and the generated machining toolpaths will be less adaptable. In this paper, the complex surface is partitioned and the cutting parameters are optimally adjusted to different parts of the workpiece during the cutting process to respond to the change in the cutting state.
