Notes

  • Disc cam (6 mm, Ø5 bore) for a radial mushroom (curved-face) follower on a 20 mm base circle: rise 12 mm over 120° with cycloidal motion, dwell 60°, return over 120°, dwell 60°.
  • Profile computed point by point (720 points) from the displacement law: the pitch curve offset inward by the 25 mm face radius.
  • Xem Studio design following Brown's figure; true size, no printing allowance (apply your own to the mating features).
