摘要： PROBLEM TO BE SOLVED: To prevent machining accuracy and moving accuracy from being reduced by the vibration of a body to be driven. SOLUTION: An acceleration detection means for detecting acceleration is mounted on the body to be driven. When the previous block is a positioning command (a3), after completion of the distribution of movement commands about the positioning command, a controller waits until a detected acceleration value detected by the acceleration detection means falls below a set value αs (a5). When the detected acceleration value falls below the set value αs, the distribution of movement commands for the next block is started (a6). After the detected acceleration value has fallen below the set value αs and vibration has stopped, cutting feed or the like is started, so that accurate machining is enabled. Moreover, no time is wasted in waiting, and processing time can be reduced. Also, an override value is varied to keep vibration from occurring during deceleration, or an acceleration/deceleration constant is varied to control vibration. COPYRIGHT: (C)2006,JPO&NCIPI
