METHOD FOR RECORDING PROCESSING TRACK WITH BITMAP AND NUMERICAL CONTROL APPARATUS

摘要

Disclosed is a method for recording a processing track with a bitmap and a numerical control apparatus. The method comprises: acquiring a recording range of a bitmap and a processing track point of a cutting tool; determining whether the acquired processing track point of the cutting tool is located within the recording range of the bitmap, and if the acquired processing track point of the cutting tool is within the recording range of the bitmap, continuing acquiring a processing track point of the cutting tool; and if the acquired processing track point of the cutting tool is not within the recording range of the bitmap, adjusting the recording range of the bitmap so as to make the acquired processing track point of the cutting tool be within the recording range of the bitmap. By means of the method for recording a processing track with a bitmap, not only can a complete processing track be recorded, the resolution of a bitmap can also be increased where the storage amount is the same.
