Problems solved by technology
[0002] The traditional three-dimensional anti-collision system is a relatively closed system. The system cannot be connected to the Internet, so it is difficult to realize remote state detection and fault diagnosis. Therefore, it is impossible to provide real-time early warning and eliminate the movement of workpieces, tools, tooling and machine tools during processing. Collision between parts, and prevent the loss caused by collision, while prolonging the preparation and cutting time, reducing the effective working hours of the machine tool
[0003] At the same time, in view of the fact that various CNC machine tool control system manufacturers (such as Okuma in Japan and Heidenhain in Germany) have considered or are already preparing to integrate anti-collision systems in high-end CNC control systems, but there is no solution suitable for comprehensive development goals

The invention belongs to the technical field of a machine tool, particularly relates to a three-dimensional online anti-collision method based on an HTM 40100 turn-milling machining center and realizes the online anti-collision detection of a horizontal turn-milling machining center. According to the method, a SINUMERIK 840D system is used as the development platform, the HTM 40100 horizontal turn-milling machining center is used as the research object, in a siemens standard interface, a self-developed three-dimensional anti-collision system is integrated into a digital control system by utilizing standard programming language provided by a siemens OEM (original equipment manufacturer) software development kit. According to the three-dimensional online anti-collision method, the three-dimensional online anti-collision system is developed and is integrated into a high-end digital control system, when collision or interference possibly occurs between workpieces, corresponding actions can be made in real time, namely shutdown is carried out and an early warning prompt is given, so that collision accidents are avoided, and the safety of the machining center is guaranteed. Meanwhile, the gap between the anti-collision system and the international like products is shortened, and the anti-collision method can be applied to other series high-end machining centers in an extended manner, so that the international competitiveness of high-end digital control equipment in China is improved.
