ABSTRACT:
A worm is rotated while a cutting torch trims the edge of the worm. The torch is mounted on an arm along with a wheel which bears against the thrust surface of the worm. The arm is mounted on one part of a carriage, the carriage moving along a guide rail under the motive influence of the worm. A pattern corresponding to the desired contour of the worm acts as a cam for the part of the carriage which carries the torch.
