Problems solved by technology

[0003] However, most of the old anti-collision mechanisms are designed for a single system (such as a single turret), without considering the situation of multiple systems
In addition, the old anti-collision mechanism is often performed when the machine tool is actually performing interpolation processing or idling, but this method takes a lot of time and cost

Embodiment Construction

[0034] figure 1 A block diagram of an anti-collision system 100 according to an embodiment of the present invention is shown. The anti-collision system 100 includes a memory 104 and a processing circuit 106. The machine tool 102 is, for example, a milling machine tool. The machine tool 102 may include M turrets TR 1 ~TR M , Where M is a positive integer greater than 1. Each turret TR 1 ~TR M Can include one or more tools respectively. It should be noted that although the present invention uses a turret as an example to illustrate the machine tool anti-collision method and its system, the present invention is not limited to this. The machine tool anti-collision method and system provided by the present invention can be applied to the anti-collision control of any multi-system machine tool.

[0035] In an embodiment, the collision avoidance system 100 may be implemented in the controller of the machine tool 102 (closed system). In another embodiment, the anti-collision system 1...

Abstract

The invention discloses a machine tool collision avoidance method and a system applying the same. The machine tool collision avoidance method includes: loading multiple processing codes; simulating multiple path traces corresponding to the processing codes; estimating multiple execution periods for running the path traces; selecting the shortest execution period from the execution periods; determines whether the distance between the trace point points on any two of the path traces is less than a safety distance within the shortest execution period; if the distance between a first trace point on a first path trace and a second trace point on a second path trace is less than the safety distance, estimating a first time point at which a first turret runs to the first trace point and a secondtime point at which the second turret runs to the second trace point; generating a collision warning if the difference between the first time point and the second time point is lower than a tolerancevalue.

Description

Technical field [0001] The invention relates to a machine tool anti-collision method and a system using the same. Background technique [0002] Due to the advancement of technology, the application of machine tools has become more and more diversified, and the number of machine tools with multiple systems has also begun to grow. A multi-system machine tool refers to, for example, a machine tool that uses multiple turrets at the same time. [0003] However, most of the old anti-collision mechanisms are designed for a single system (such as a single turret) without considering the situation of multiple systems. In addition, the old anti-collision mechanism is often carried out when the machine tool actually performs interpolation processing or empty running, but this method requires a lot of time and cost. Summary of the invention [0004] The present invention relates to an anti-collision method for machine tools and a system using the same. The method of rapid simulation can be us...
