Abstract:
1. An interference preventing device for a machining machine, comprising: a parameter database module, providing protection information corresponding to a target component of the machining machine in response to a control command; and a control module, providing the control command in response to an operation event, the control module further obtaining a basic envelope of the target component by executing envelop calculation for the target component according to the protection information, and the control module further obtaining a multi-hierarchical area by having the basic envelope segmented into a plurality of sub-areas according to a multi-hierarchical protection parameter and removing a part of the plurality of sub-areas not interlaced with the target component, wherein, the control module determines whether an interference event has occurred between the multi-hierarchical area and a correlated object, so as to determine whether an interference event occurs on the target component and provide a control signal to control the operation of the machine when the interference event is detected; the control module further determines a size of the basic envelope according to a dynamic protection parameter corresponds to distance information indicating a distance between the target component and the correlated object, so as to provide the multi-hierarchical area, which is dynamic adjustable, for the target component according to the dynamic protection parameter; wherein the greater the distance between the target component and the correlated object is, the higher a value of the dynamic protection parameter is, and a larger size of the basic envelope corresponds to, while the smaller the distance between the target component and the correlated object is, the smaller the value of the dynamic protection parameter is, and a smaller size of the basic envelop corresponds to.
