ABSTRACT:
A tracing stylus assembly for controlling operation of an electrically controlled machine tool produces analog electrical signals which are representative of displacement of a stylus member from a center rest position in any direction in at least two transverse planes which correspond to planes of movement available in the machine tool during machining operations. The electrical signals from the tracing stylus are connected to standard motor control amplifiers in the machine tool to control movement of the machine tool. The electrical signals from the stylus may be easily processed to provide adjustments to operation not otherwise possible. For example, the null point of the stylus member can be adjusted electronically as can the correlation between the amount of travel of the stylus and the rate of response of the machine tool. A computer operated machine can be easily programmed using the stylus assembly of the invention, and the stylus assembly can be used as a fail-safe device to automatically halt operations of the machine when under automatic computer control if the control or computer malfunctions so that the machine tool starts to move in a manner that would ruin a part being machined.
