Abstract

A control system for automatically setting the positions of a plurality of tool holders of a wood working machine in accordance with instructions in a memory M has associated with each tool holder a servo motor SM1-SMn and a position detector S1-Sn selectively connectable by a pair of switches A, B to a central computing and processing apparatus CP. On initiation the central processor places switches A & B in a first position and selects the appropriate desired position from memory M to drive the tool holder until the feedback signals from the position detector indicate that the work tool holder has reached the preset position stored in the memory. Thereupon the central processor changes the switches to a subsequent position and adjusts the position of the next work tool holder and so on until all are positioned correctly. The memory may contain a number of different setting schedules for setting the machine to perform different operations. <IMAGE>
