Embodiment Construction

[0021] The present invention will be further described in detail below.

[0022] In the present embodiment, when machining the glass workpiece of the 3C product, a torque feed feed-by-feed compensation resolution is used in the servo driver, the main method is to perform TFF torque feed-feed compensation debugging in the manual interface of the controller.

[0023] Before performing TFF torque feedback compensation, it is necessary to adjust the axial gain of the machine on the controller to ensure that the axial motor inertia is correct, and does not vibrate when moving can smoothly perform TFF torque feedforward compensation debugging.

[0024] In order to ensure the axial motor inertia ratio is correct, the axial motor inertia estimate is required on the controller, and the operation method of the axial motor inertia estimate is the first access parameter setting interface set parameters, and then turn on the debugging function to debug, Finally, start the automatic mover funct...

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 ...
