[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 collision avoidance system 100 includes a memory 104 and a processing circuit 106 . Machine tool 102 is, for example, a milling machine tool. 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 One or more knives may be included 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 thereto. The machine tool anti-collision method and its system proposed by the invention can be applied to the anti-collision control of any multi-system machine tool.
[0035] In one embodiment, the anti-collision system 100 may be implemented in the controller of the machine tool 102 itself (closed system). In yet another embodiment, the anti-coll...

The invention discloses a machine tool anti-collision method and a system applying the same. The method includes: loading multiple processing codes; simulating multiple path trajectories corresponding to these processing codes; estimating multiple execution periods of running these path trajectories; Select the shortest execution period among the execution periods; determine whether the distance between the trajectory position points of any two of these path trajectories is less than a safe distance within the shortest execution period; when the first trajectory location point in the first path trajectory is When the distance between the second trajectory position point in the trajectory is less than the safety distance, estimate the first time point when the first turret moves to the first trajectory position point and the second time point when the second turret moves to the second trajectory position point; When the time gap value between the first time point and the second time point is lower than the tolerance value, a collision warning is generated.
Description
technical field [0001] The invention relates to a machine tool anti-collision method and a system applying the same. Background technique [0002] Due to the advancement of technology, the application of machine tools has become more and more diverse, and the number of multi-system machine tools has also begun to grow. A multi-system machine tool is, for example, a machine tool that uses a plurality of 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 performed when the machine tool is actually performing interpolation processing or idling, but this method takes a lot of time and cost. Contents of the invention [0004] The present invention relates to a machine tool anti-collision method and a system using the same. It can firstly detect whether the distance between t...
