摘要： A dual template assembly for permitting rough and finish cuts to be made on successive passes of a tracer lathe includes separate rough and finish templates. A pneumatic cylinder selectively causes sliding movement of the rough template relative to the finish template. The rough template is initially moved to an extended position, wherein an edge thereof is exposed over an edge of the finish template. A lathe tracing stylus is moved across the rough template edge, causing the lathe to remove material from a workpiece in accordance with the rough shaped defined thereby. A sensor generates a signal when the tracing stylus completes its movement across the rough template. In response thereto, the control circuit causes the rough template to be moved to a retracted position, wherein the finish template edge is exposed over the rough template edge. The tracing stylus is then moved across the finish template edge, thereby causing the lathe to remove material from the workpiece in accordance with the final shape defined thereby. The control circuit then returns the rough template to the extended position so that the entire operation may be repeated.
