Method for solving highlight quadrant fringes through driver torque feed-forward compensation

Abstract

The invention discloses a method for solving highlight quadrant fringes through driver torque feed-forward compensation. The method comprises the following steps: 1) adjusting the axial gain of a machine tool on a controller to ensure that the inertia ratio of an axial motor is correct and vibration does not occur during movement; (2) conducting torsion sharp corner debugging on a human-computer interface of the controller; 3) setting a circle following plane, and starting a parameter compensation function of the controller; 4) ensuring correct setting of a workpiece coordinate system, and performing function learning; and 5) changing the operation mode into starting compensation, and checking a debugging result. According to the method for solving the highlight quadrant veins by utilizing the driver torque feedforward compensation, when a glass part of a 3C product is processed, the torque feedforward compensation can be carried out in the servo driver, the quadrant veins during glass processing can be effectively solved, the debugging process is simple, the operation is convenient, and the practicability is relatively high.

Description

Technical field [0001] The present invention relates to the field of mechanical control processing, and more particularly to a method of solving high-efficiency restricted pattern using a drive torque feedforward compensation. Background technique [0002] In the process of the glass part (generally screen) of the 3C product, it is generally more common in 2.5d glass and 3D glass, where D refers to the radians of the screen protected glass, 2.5D glass is a plane in the center of the glass. Then, then the edges are corrected on the basis of the planar glass, and 3D glass refers to the screen that includes radians of the entire surface. 2.5D glass and 3D glass are processed and used in processing and use, and additional quadrant lines are generated, which will affect the effect of the screen. [0003] The prior art is generally in processing, speed feedforward compensation from the CNC machine controller to eliminate the viscosity generated during the quadrant or zero speed, which ...

Problems solved by technology

However, when 2.5D glass and 3D glass are processed and used, they will leave traces in the quadrant and produce additional quadrant patterns, which will affect the effect of the screen.

[0003] In the prior art, the speed feed-forward compensation is generally performed from the controller of the CNC machine tool during processing to eliminate the stickiness generated when the machine tool is started at quadrant or zero speed, thereby reducing the effect of quadrant lines and commutation lines. But there is no further solution to the problem of quadrant pattern
