Abstract
A positioning control method (80) has a setting section (81) for setting a comparison reference value in accordance with a machine tool in advance, a detecting section (82) for detecting a command value by the rapid traverse command G00, a comparing section (83) for comparing the comparison reference value and the command value, and a determining section (84) for changing the rapid traverse command G00 to a linear interpolation command G01 when the command value is smaller than the comparison reference value, executing the rapid traverse value G00 when the command value is larger than the comparison reference value, and selecting either one of the rapid traverse command G00 or the linear interpolation command G01 when the comparison reference value is equal to the command value. Less effective short-distance rapid traverse command is converted to the linear interpolation command, thus speeding up positioning control to make an entire processing of the workpiece faster.
