Abstract: In order to achieve accurate positioning of drilling and milling, the movement of drill bit is monitored and corrected in real time with the help of frequency converter, servo driver and the use of grating ruler. At the same time, the continuous trajectory interpolation movement can be realized through the DMCS control system, so as to drill and remove chips for large area of materials. That can realize the automatic drilling and tapping of a large number of small holes in soft materials.

Key words: frequency converter, servo drive, grating ruler, DMCS, drilling machine
