Abstract: A machining path modification method includes the following steps: analyzing the machining path of a machining program to decide whether any point of the machining path is an avoidant point; obtaining an abnormal point of the machining path; and if the abnormal point exists, modifying the machining program to add an abnormality avoidant path on the avoidant point of the machining path.

Abstract: A processing method for automatically generating machining features is provided. A workpiece CAD file is obtained to perform a CAD numerical analysis on a blank body. With the workpiece CAD file being used as a target, a workpiece CAD appearance is compared with the blank body to obtain a feature identification result of a first to-be-processed blank body, which includes identifying data of a to-be-removed blank body and a feature of a first processing surface. A geometric analysis is performed on the first processing surface feature and a tool selection range is determined. A virtual cutting simulation is performed on the first processing surface to generate a processed area data and an unprocessed area data. A spatial coordinate mapping comparison between the unprocessed area data and a surface data of the workpiece CAD file is performed to obtain a feature identification result of a second to-be-processed blank body.
