ABSTRACT:
At least one workpiece is rotated synchronously with a model in a contour-copying lathe. A feeler engages the model and is linked to a tool similarly engageable with the workpiece so that as the feeler rides up and down and travels along the model the synchronously displaced tool similarly shapes the workpiece. Those preshaped regions on the model corresponding to the surfaces on the workpiece which are not to be shaped are provided with extensions so that the tool is lifted from the workpiece at these preshaped surfaces.
