Problems solved by technology
For the commutation lines produced by CNC machine tools, the current debugging process starts with the electronic circle. The electronic circle only considers the motor end, and does not consider the influence of the end cutting point by the mechanism error, so the debugging space is limited.

The invention discloses a method for eliminating the machining reversing lines of a numerically-controlled machine tool by using a ball bar. The method comprises the following steps of: (a) debugginglathe axial motor parameters by using a controller to ensure correct motor gain and inertia ratio ; (b) carrying out speed sharp angle debugging by using the controller to enable the roundness of plane electronic rounding to be less than 1 micron; and (c) measuring a plane sharp corner and a back clearance by using the ball bar, and adjusting the compensation parameters of the controller to enablethe sharp corner and the back clearance of the ball bar to be less than 1 micron. Lathe axial gain is adjusted, so that vibration does not occur during movement; the sharp corner, the back clearanceand the roundness of the ball bar are all debugged so as to be smaller than 1 micron, and therefore, the problem of reversing lines caused by static friction force in numerical control machining can be effectively solved.
Description
technical field [0001] The invention belongs to the technical field of CNC machine tool processing, and relates to a method for eliminating commutation lines, in particular to a method for eliminating commutation lines in CNC machine tool processing by using a ballbar. Background technique [0002] On CNC machine tools (such as milling machines), the axial direction of the machine tool often sticks when the direction is reversed or started at zero speed, resulting in changes in light and shadow on the workpiece where the direction is reversed, resulting in commutation lines. For the commutation lines produced by CNC machine tools, the current debugging process starts from the electronic circle, which only considers the motor end, and does not consider the influence of the end cutting point by the mechanism error, so the debugging space is limited. Contents of the invention [0003] The purpose of the present invention is to provide a method for eliminating the commutation ...
