When shaft 17 rotates about axis A-A, motion is transmitted simultaneously to cam blank 1 and to template 2. Blank 1 is rotated through worm 3, worm wheel 4, and links 5 and 6. Template 2 is traversed in the crosswise direction by worm 3, worm wheel 4, gear 7 and rack 8 which is secured to slide 9, carrying template 2. As slide 9 is traversed, template 2 engages stylus 10, imparting longitudinal displacement to slide 11. Slide 13 with end milling cutter 14 travels together with slide 11. Slide 9 is adjusted in the longitudinal direction when the template is changed by screw 16. The minimum distance from the end face of the blank to the cam slot is set up by an adjustment made with screw 15. The depth of the cam slot is set up by adjusting cross slide 13 with screw 12.
