Problems solved by technology

The numerical control systems used by most domestic machine tool manufacturers are imported external systems. Due to the closedness of foreign high-end numerical control systems, it is very difficult to fully grasp the logical relationship and operating mechanism of the numerical control system, so it is difficult to realize the numerical control system and The communication of 3D virtual machine tool is technically difficult

Abstract

The invention discloses and realizes a real-time anti-collision method weakly associated with a numerical control system for a numerically-controlled machine tool. Three-dimensional real-time processing simulation is carried out by virtue of the numerically-controlled machine tool, a signal of interest is acquired by virtue of an anti-collision system and is processed by adopting a prediction algorithm in a software system, then a virtual numerically-controlled machine tool is driven to carry out simulation, prediction simulation is carried out on wrongful collision or interference appearing in a machining process or when an operator operates the numerically-controlled machine tool and warning is carried out, and a numerical control system stopping signal is returned and the machine tool is protected.

Description

technical field [0001] The present invention relates to the field of numerical control machine tools in the equipment manufacturing industry. More specifically, the present invention relates to the simulation processing of numerical control machine tools in the working process. The guarantee and protection of numerical control machine tools are realized by simulating the working process of virtual machine tools and conducting two-way communication with the numerical control system. . Background technique [0002] With the continuous development of CNC machining technology and the increasing processing requirements of complex curved surface structures, multi-axis CNC machining solutions such as multi-axis linkage machining, turning and milling, etc. have been more and more widely used. However, complex machining objects have higher requirements for the planning and optimization of machining tool paths and the operator's technical level. Although many commercial CAM softwares...
