(1) Add fast return to zero function. When the tool starts processing from one end to the other end along the z axis, the tool needs to return to the starting point along the z axis to restart the processing, which can increase the Z-direction rapid return to zero function to reduce the auxiliary time and improve the processing efficiency.
(2) Multiple tools can be installed on the tool holder or multiple x feed tool holder, and the spacing between the tools is a multiple of the deflection distance of the folding line groove, so that when the drum is rotated, the processing of multiple rope grooves can be completed at the same time, thereby improving the processing efficiency.
