<p>PROBLEM TO BE SOLVED: To shorten a process and to reduce die production cost by position- controlling a feed shaft motor based on obtained command position output and a present feed shaft position which is fed back. SOLUTION: A shape calculation quantity correction part 11 operates shape correction quantity in respective edge position command positions and vector- distributes shape correction quantity to respective feed shaft direction components from respective shape correction directions calculated in a correction direction calculation part 10. A shape correction range judgment part 13 blocks a gate by using an AND gate 14 so that shape correction quantity is taken out to an addition part 3 from the shape correction quantity calculation part 11 only when the respective edge position command positions are contained in a shape correction range which is set and stored in a shape correction range setting/storage part 12. The addition part 3 vector-adds respective shape correction quantities to the respective edge position command positions, obtains the edge position command positions after shape correction, sends the obtained edge position command position after shape correction as command position output and sends it to a feed shaft motor driving part 4.</p> |
