    摘要: An arrangement for machining surfaces with a numerically controlled tool in which the tool is provided with a parabolic profile to obtain a substantially smooth surface finish. The workpiece to be machined is moved relative to the cutting tool in substantially a plane of the workpiece. After milling a contour along that plane, the workpiece or the tool is incremented to an adjacent parallel plane for the purpose of milling another contour on the workpiece. The slope of the surface element on the workpiece between the adjacent planes is computed, and the cutting tool is oriented so that the portion of the tool in contact with the workpiece along that surface element, possesses the computed slope. The cutting tool may be formed with cutting edges having straight-line segments interconnected and directed substantially along a parabolic surface. The slopes on the cutting edges of the tool vary in magnitude from substantially zero to infinity.

    摘要: A STEP FEED DEVICE FOR DUPLICATING MILLING MACHINES EQUIPPED WITH A PANTOGRAPH OPERATED BY AN ADJUSTABLE STOP WHICH IS PROVIDED WITH A SPINDLE SCREWED INTO A THREADED SLEEVE AND ARRANGED FOR DISPLACEMENT IN A CASING. THE SLEEVE IS BIASED BY A SPRING AT ONE END THEREOF AND DURING DISPLACEMENT OF THE SLEEVE IN THE CASING A ROTARY CONTROL DEVICE ENGAGES THE SLEEVE SO THAT IT CAN TURN IN ONLY A SINGLE DIRECTION WITH RESPECT TO THE SPINDLE. TO OBTAIN A STEP FEED, THE PANTOGRAPH NEED ONLY BE LIFTED SO THAT THE THREADED SLEEVE CAN BE SHIFTED BY THE SPRING AND THEN LOWERED AGAIN TO THEREBY CHANGE THE WORKING PLANE OR LEVEL OF THE PANTOGRAPH.

    摘要: A device for controlling the cyclic motion of a multi-cycle profiling machine, so as to selectively actuate a cylindrical cycle, a shaping cycle, or a composite cycle, simply by adjusting the relative operative positions of two switches and the retarding stroke of a cut spool, without necessitating any change of machine parts. The two switches are related to said cut spool, a profiling slide, and a stylus.
