A cutter head follow-up control method and control device of a glass cutting machine

Abstract

The invention discloses a cutter head servo control method and a cutter head servo control device for a glass cutting machine. The method is used to control a cutter head servo controller in order to drive a cutter head servo shaft to drive a cutter head to rotate. The method comprises the following steps: providing a cutter head servo parameter as a target cutter head servo parameter; acquiring a target cutter head servo angle; and performing angle interpolation motion. Angle calculation is performed according to the target cutter head servo parameter to get the target cutter head servo angle, and interpolation is performed according to the target cutter head servo angle to get the output control pulse of the cutter head servo shaft. The cutter head servo controller receives the output control pulse, and makes the cutter head servo shaft rotate, so as to achieve a cutter head servo function. By using the method and the device, the cutter head of a numerical control glass cutting machine can be driven to rotate, the cutter head is driven to rotate according to the processing track in glass processing, and the problem that the processing requirements cannot be met for processing of special-shaped glass as the cutting edge direction of the cutter head is inconsistent with the tangential direction of the track is solved.

Description

technical field [0001] The invention relates to a control method and a control device thereof, in particular to a cutter head follow-up control method of a glass cutting machine and a control device thereof. Background technique [0002] Glass cutting machine refers to a kind of processing machinery dedicated to glass processing and blanking. At present, low-grade glass cutting machines are generally operated manually, and medium and high-end glass cutting machines are generally realized by CNC system for automatic or semi-automatic processing of glass cutting. Due to the particularity of glass processing, diamond is generally selected as the material of glass cutter head. The cutting edge of the diamond tool is linear. When processing special-shaped (such as arc) glass, if the direction of the cutting edge of the cutter head is inconsistent with the tangent direction of the trajectory, the processing effect will be poor, and the tool will be damaged in severe cases.

AI Technical Summary

Problems solved by technology

[0004] In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides a cutter head follow-up control method and its control device for a glass cutting machine, so that in the numerically controlled glass cutting machine, the cutter head can follow up. During glass processing, the cutter head follows the processing track, which solves the defect that the cutting edge direction of the cutter head is inconsistent with the tangent direction of the track when processing special-shaped glass, which cannot meet the processing requirements
