Abstract
A machine tool which is a template tracing attachment which significantly reduces the slack or hysteresis in the operation of a machinist's lathe. Optical or magnetic scales and respective sensors assist in the accuracy of producing workpieces from a template. The accurate reproduction of a workpiece can be manual or computer assisted. The attachment can be retrofitted or included in the production of a lathe.
Claims20
A template tracing attachment assembly for a machinist's lathe comprising:
- a cross slide containing a ball screw for cooperating with a ball screw nut fixed in said cross slide;
- a motor means for driving the ball screw;
- a first tracer encoder device and stylus assembly proximate to a template;
- a second encoder device located inside the motor means;
- and
- a computer system connected for receiving parameter signals transmitted from the first tracer encoder device, recording said parameter signals and transmitting said parameter signals to said second encoder device to drive said ball screw and said cross slide to a position whereby a lathe cutter can duplicate a configuration of a template in an x-direction.

A template tracing attachment assembly for a lathe comprising:
- a cross slide containing a retrofitted ball screw for cooperating with a ball screw nut fixed in said cross slide;
- wherein the ball screw nut has recirculating ball bearings within for cooperation with the ball screw, whereby slack in the x-direction is substantially eliminated;
- a motor means for driving the ball screw;
- a carriage for supporting said cross slide and a cutter;
- a first tracer encoder device and stylus assembly proximate to a template;
- a second encoder device located inside a tracer motor;
- a scale element positioned parallel to the template between holders of the template, whereby a lathe operator can visually view linear measurements involved in the movement of the carriage for various portions of the template;
- and
- a computer system connected for receiving parameter signals transmitted from the first tracer encoder device, recording said parameter signals and transmitting said parameter signals to said second encoder device to drive said ball screw and said cross slide to a position whereby the lathe cutter can duplicate the configuration of the template in an x-direction.
