AI Technical Summary

Technical Problem

In the existing technology, machine tools cannot effectively suppress the occurrence of machining defects when abnormal conditions occur during the machining process, especially when the tool is damaged, the machining quality of the workpiece cannot be guaranteed.

Method used

By introducing trajectory generation, program generation, motion control, feedback control, and anomaly detection components into the machine tool machining system, correction instructions are generated to correct the tool path and feed rate. Anomalies are identified using a simulation device, and correction instructions are generated to correct the machining program.

Benefits of technology

It effectively suppresses machine tool malfunctions, improves processing quality, reduces processing defect rate, and ensures the processing quality of workpieces.

Abstract

A machining system includes a CAM device that generates a machining program including a motion code based on three-dimensional shape data, and a numerical control device that controls a motor of a machine tool. The machining system includes a monitoring device that detects an abnormality of the machine tool based on a driving state of the motor. The machining system includes a correction device that generates a correction instruction that corrects a parameter at the time when the CAM device generates the machining program. The correction device transmits the correction instruction to the CAM device so that at least one of a curvature of a tool path at the time when the abnormality occurs and a feed rate of a tool is corrected.
