摘要

PROBLEM TO BE SOLVED: To provide a cutting machine which can shorten a cutting time without marring the sharpness of a cutting blade, to thereby improve the productivity thereof, and to provide a method of grinding the cutting blade of the cutting machine, a cutting blade grinding data creating device, and a method of cutting an object to be cut by the cutting machine.;SOLUTION: According to the method of grinding the cutting blade, after a continuous cutting integrated value exceeds a predetermined value from a time point at which the cutting blade 8 has been replaced and/or a time point at which the cutting blade has been ground, a virtual grinding point at which the cutting blade is ground when lifted up, is set on one component part of the object to be cut. Then if a continuous cutting quantity from the virtual grinding point to completion of the cutting of the component part is within a specified value, the cutting blade is ground by a grinding device 14 during a time from the completion of the cutting of the part to starting of cutting of another part.;COPYRIGHT: (C)2009,JPO&INPIT
