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 chatter avoidance method and device is provided, including steps of: providing a stable operating condition plot; partially removing a first layer of a workpiece with a predetermined first removal depth according to a safe removal depth of the stable operating condition plot and sensing a chatter caused by the removal operation; if no chatter is sensed, completing the removal operation, otherwise, continuing to partially remove the first layer with a second removal depth less than the predetermined first removal depth; and determining a minimum removal depth according to the removal operation, and removing a last layer of the workpiece with a last removal depth less than or equal to the minimum removal depth, allowing the workpiece to have a target thickness. The disclosure prevents a chatter from continuously occurring without requiring a shut-down and thereby maintains a desired production rate.
