Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0028] Such as figure 1 As shown, it is a schematic diagram of a dual-controller synchronous contour control method in the present invention. Before the dual-controller synchronization starts, the first controller and the second controller will save the same graphic contour map, and the same contour map defines the same Starting point marker information. The method of the invention can be appl...

Abstract

The invention discloses a dual-controller synchronization contour control method. The method comprises the steps that a given pattern contour is loaded into first and second controllers; the first controller carries out motion trajectory control according to the given pattern contour; a track position point is coded based on a travel, and a synchronization control signal with coding information based on the travel is transmitted to the second controller; the second controller receives the synchronization control signal and carries out parsing to acquire a track position point, so as to synchronize with the first controller; and the shape of a light spot is controlled according to the pattern contour of the track position point. The method can be applied to laser glass cutting of a crack control method, so that a numerical control system controller (the first controller) synchronizes with a variable light spot controller (the second controller) based on the pattern contour. Compared with other synchronization control methods, the dual-controller synchronization contour control method has the advantages that for any complex pattern, a coding method is always simple and effective; less data are transmitted; and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of industrial motion control, and more specifically relates to a dual-controller synchronous contour control method. Background technique [0002] In special processing, the processing tools are not limited to ordinary tools, and EDM, electron beam, ion beam, ultrasonic, water jet, laser light knife, etc. are often used. In conventional machining methods, the shape of the tool is constant, but in special machining, the shape of the tool is flexible and variable, and it is also time-varying. In the laser processing glass based on the control crack method, since the shape of the laser spot needs to always coincide with the given graphic outline, it is required that the laser spot shape changes with the change of the path while the laser is moving, so as to achieve high-precision processing of the glass cover. Therefore, it is required that the shape of the laser spot must follow the path to be processed. At ...
