AI Technical Summary

Technical Problem

When the existing CNC machine tool system detects interference between paths, it cannot effectively solve the three-dimensional interference problem of non-common rail models, and only judges the distance without considering the movement speed, resulting in inaccurate deceleration stop or tight stop, resulting in damage to the machine tool vibration.

Method used

By setting the three-dimensional coordinates of the restricted area and the three-dimensional coordinate positions of the checkpoint in the CNC machine tool system, the coordinates of the detection point and the coordinates of the restricted area are calculated based on the current position, the target position and the set data, and the detection process is performed in each control cycle to determine whether it is in the restricted area or close to it, and to slow down or stop movement.

Benefits of technology

Accurate detection and slowing down of three-dimensional interference is achieved, interference is avoided, and the safety and scope of application of the machine tool are improved.

Abstract

The invention relates to a method for realizing detection processing aiming at interference between paths in a numerical control machine tool system, which comprises the following steps of: setting a three-dimensional coordinate of a forbidden zone in a path of which interference needs to be detected, and setting an influence relation of the position of the forbidden zone to the movement of a shaft controlled by other paths; setting the three-dimensional coordinate position of the check point and the influence relation of the motion of the axis of the path; calculating detection point coordinates and forbidden zone coordinates of the current position and the target position according to the current position, the target position and set data in each control period; and executing a detection process. The invention further relates to a device for detecting and processing the interference between the paths in the numerical control machine tool system, a processor and a computer readable storage medium of the processor. By the adoption of the method and device for achieving detection processing on the inter-path interference in the numerical control machine tool system, the processor and the computer readable storage medium of the processor, the problem of three-dimensional interference detection is solved, and the effects of accurate detection, deceleration stopping, interference avoiding and machine tool safety improving are achieved.
