Space tool radius compensation for five-axis flank milling is one of importantfunction in the five-axis CNC system. It not only simplifies NC programming but alsoimprove efficiency. At present, effect of space tool radius compensation for five-axisflank milling is not ideal in the actual processing. Therefore, the space tool radiuscompensation for five-axis flank milling is not perfect that need for furtheroptimization.This paper analyzes the characteristics of five-axis flank milling and proposed theoptimization scheme to improve the space tool radius compensation of five-axis flankmilling. It mainly includes the following research contents:1. The research of approach and retraction behavior of space tool radiuscompensation. The algorithm about to select different approach or retraction behaviorbased on different contour when the function of tool radius compensation establish orcancel is proposed.2. The research of smooth approach and retraction behavior of space tool radiuscompensation. It is used to reduce cut marks left in the back surface of work piece whentool approach and retraction work piece. It is through the tool along a line, quarter circleor semi-circle to tangential approach and retraction contour to realization.3. The research of compensation at corner of space tool radius compensation. Thespecial compensation at corner is proposed in exceptional case and optimization schemeis proposed in compensation at corner.Based on VERICUT platform, the simulation of the optimization algorithm is run,the results of the simulation show that the function of space tool radius compensationfor five-axis flank milling has been improved. |
