ABSTRACT:
A system for generating a magnetic tape having thereon signals corresponding to movement of a co-ordinate drive carriage driven by an optical follower tracing a line drawing. The tape is used to provide signals to an encoder connected to the drive train of a co-ordinate drive positioning system used to carry a cutting device or other apparatus over a workpiece thus reproducing the line drawing on the workpiece with the cutting device or other apparatus. An improved co-ordinate drive oxy-fuel plate cutting machine can be constructed according to the disclosure.
