Abstract
An apparatus for automatically causing a workpiece to engage a rotary tool. A pulse signal generated by rotating a reference workpiece is stored, and then a pulse signal generated by rotating a mounted workpiece is counted. The counted pulse signal and the stored pulse signal are compared, and when they coincide with each other, the workpiece is brought into engagement with the rotary tool. When the rotary tool is shifted, the stored pulse signal information is updated, and then a pulse signal generated by rotating a mounted workpiece is counted. If the updated stored pulse signal information land the counted pulse signal information are equal to each other, then the workpiece is taken into engagement with the rotary tool.
