摘要： PURPOSE:To perform correction so that the start position of next operation is securely kept by commanding feeding operation in two stages wherein a feed speed is switched from high to low so that a return to the start position of following operation is made after reverse fast forwarding. CONSTITUTION:A feed mechanism D is forwarded fast by a reverse fast forwarding means E to a 1st command position P1 in the opposite direction from next operation before the next operation when it is confirmed that current operation reaches a target position X1. Then a return correcting means F returns the feed mechanism D at an intermediate speed from the 1st command position P1 to a 2nd command position P2 in the same direction as the feed direction of the next operation and then sends it at a low speed to the start position of the next operation matching the target position X1 of the current position. Namely, a uniaxial feed mechanism D, for example, is overfed to beyond the start position X2 of the next operation to the position P1 which deviates by a feed quantity x1 larger than a backlash error DELTAL, and then makes an approach at the intermediate speed in the next feed direction and further approaches the start position P2 of the next operation at the low speed, so the feed mechanism D can be stopped accurately at the target position.
