introduction： A process performance test that determines how easily a material is machined to a certain dimensional accuracy and to a certain surface quality。It is usually measured by the highest cutting speed under a certain tool life。For finishing﹐It is also necessary to increase the machining accuracy and surface quality indicators。Sometimes also to cutting power﹑The cutting force or chip breaking is measured。 The relationship between tool life and cutting speed is mainly according to the figure Tool wear curve Wear curve test method in the evaluation。 At the specified cutting depth

introduction：Whether its turning or milling，In the processing of contour，Programming can be simplified with the tool radius compensation function。When turning，If the false knife tip is used as the knife point，When machining taper or arc，Undercut or overcut will occur。As shown in the figure6-1As indicated。Only the center of the arc that controls the knife tip is used as the knife point，In order to avoid the phenomenon of undercutting and overcutting。 figure1The phenomenon of undercutting and overcutting when controlling the false tip When contour milling is done with an end mill，Because the cutter point is at the intersection of the bottom surface of the milling cutter and the center of rotation，Only when the tool point deviates from the profile by one tool radius，ability
