Description
Cam 1 rotates about fixed axis D and cam 2 rotates about fixed axis B. Slide 3 of lathe tool 6 reciprocates along fixed guide a and carries roller 5 which rolls a long the working surface of cam 2. Tool 6 is clamped in a holder which oscillates about axis A of slide 3 and carries roller 4. Roller 4 rolls a long the working surface of cam 1. Cam 2 controls the reciprocating movement of tool 6 so that it turns the required contour on the workpiece. Cam 1 controls the oscillation of tool 6 to maintain a constant cutting angle in turning contoured workpieces. Cams 1 and 2 are independently controlled by suitably programmed facilities.
