Title:
METHOD FOR MACHINING WORK
Document Type and Number:
WIPO Patent Application WO/2006/016420
Kind Code:
A1
Abstract:
When machining a work W, the wear of a tool T at the time of machining is estimated, and a position command generated according to a preset machining program is corrected when required during machining according to the estimated wear of the tool T, so that the work W is machined into a desired shape in accordance with a corrected position command. On the other hand, wear of the tool T when machining is interrupted is calculated and when machining is resumed at the interrupted position, a position command generated according to the preset machining program is corrected according to the calculated wear of the tool T so that the position of the tip of the tool T when machining is interrupted coincides with the position of the tip of the tool T when machining is resumed, and then the work W is machined in accordance with a corrected position command.
