Notes
- Disc cam (6 mm, Ø5 bore) for a radial roller 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 roller-centre (pitch) curve offset inward by the 5 mm roller radius.
- Xem Studio design following Brown's figure; true size, no printing allowance (apply your own to the mating features).
