Abstract: A programmable system employs a driver computer control programmed via a personal computer having a keyboard input. The controller sends programmed signals via the keyboard input to a three-dimensional coordinator circuit which generates X, Y and Z drive signals representing left, right and height positions of a scribe which is in alignment with the surface of a workpiece. Positioned between the three-dimensional coordinate circuit and the scribe is an electronic-to-mechanical conversion means in the form of a machine piston which converts the electrical X, Y and Z programmed instructions to a servo and trigger network interfaced with the scribe. An angle position driver directly couples, in parallel, the driver computer control and the three-dimensional coordinating circuit with the servo and trigger network. By programming the instructions into the system, the scribe can follow or coordinate with the workpiece surface whether it is flat, curved or irregular.
