Accompanying fllmstrip $1 Shows how to set up the machine; how to set up and align workpiece on milling machine table; how to position table and workpiece In relation to the cutter; and how to rough and flnish-mill the workpiece CUTTING A TAPER WITH THE COMPOUND REST AND WITH A TAPER ATTACHMENT. Castle 1942 llmin sd $21.44 621.9 sh-c-tr-ad Guide Produced by U.S. Office of Education. Accompanying fllmstrip $1 Shows the operations necessary to cut a sharp and slight taper on a gear blank. Considerable detail and emphasis are given to the care and operation of the machine, the use of the compound rest for turning a sharp angle surface, the setting of a compound for turning any angle within its range, the setting of the tool for taper turning, the principles of the taper attachment, the correct setting of the taper attachment for the given angle, and the use of a protractor and a ring gage for checking the angle of taper CUTTING AN EXTERNAL ACME THREAD. Castle 1942 16min sd $27.88 621.9 sh-c-tr-ad Guide Produced by U.S. Office of Education. Accompanying fllmstrip $1 "The picture opens with a description of the acme thread, giving its shape and emphasizing the fact that the broad surfaces on the thread provide for the transmission of power and motion with the least amount of friction. "The operator Is shown studying a drawing and a table showing the dimensions of acme threads is used by him to get the dimensions of the thread he is to cut. "The method used when setting the crossfeed index for the roughing cut is clearly shown as is also the manner In which the operator sets the stocking tool to the work and checks this setting after a preliminary cut has been taken. A magnified closeup gives the outline of a stocking tool. Commentary is used to discuss its shape and the necessity for using such a tool. The various steps followed when taking the roughing cut are shown in detail from the beginning of the cut to the finish. "The method the operator uses for setting a finishing tool by means of a setting gage, together with the procedure followed when picking up the thread left by the stocking tool are shown in detail. Also the use of the threading dial and the method by which it is set are shown in detail. "After the cross-feed index shows that the thread has been cut to depth, a gage is tried on the thread showing that the thread is still slightly oversize. "The picture shows how this condition Is corrected and closes with a resume of the various items shown in the picture." Business screen CUTTING AN EXTERNAL NATIONAL FINE THREAD.
