Riassunto

Excerpt from Automatic Screw Machine Practice, Vol. 3: Circular Form and Cut-Off Tools for the Brown and Sharpe Automatic Screw Machine

It is obvious that, as the condi-tiofis'flfidér 3which the work is done and the limits allowed on it vafy be impracticable to lay down hard and fast rules in: mate; the application of circular tools, but the following suggestions will be found applicable to general conditions. At D, Fig. 3, is shown a method sometimes used to advan tage in making shouldered screws or other pieces of a similar char acter. This forming operation is not recommended when the piece to be made is required to be very accurate, as a slight eccentricity in the spring collet would cause the part f to be out of true with the part a. In cases where accuracy is required. The part a could be roughed down with the cut-off tool and a light finishing cut taken with a box-tool. At D, is shown an improved method of forming the same piece, as the form tool here removes the burr from the head.
