A new type of tracer for copy milling machines has been successfully developed in order to produce the die cavity at considerably higher accuracy than that of the conventional tracer. Tracing mechanism and accuracy of this new tracer are discussed comparing with the conventional tracer. The new tracer has a special mechanism which makes the stylus always ahead of the cutting tool in the direction of tracing feed. Detecting the small displacement of the stylus caused, by the variation of inclination of the model profile, the direction of tracing feed is corrected. It has been experimentally ascertained that the new tracer gives remarkably high tracing accuracy because of small displacement of the stylus. Tracing inaccuracy of the-new tracer depends only upon the inclination of the model profile, therefore the error can be easily compensated by using a stylus slightly larger than the cutting tool.
