Model a plate cam as ONE solid. Frame: cam axis parallel to Z through (X=10, Y=5); the polar angle phi is measured about that axis in the XY plane from +X toward +Y, in the cam's own (fixed) frame as modelled. Pitch curve (path of the centre of an in-line roller follower of radius 8): r(phi) = 38 + s(phi), with s in mm and phi in degrees: - 0 <= phi < 120: cycloidal rise, s = 14·(phi/120 - sin(2·pi·phi/120)/(2·pi)). - 120 <= phi < 180: dwell, s = 14. - 180 <= phi < 300: simple-harmonic return, s = 7·(1 + cos(pi·(phi-180)/120)). - 300 <= phi < 360: dwell, s = 0. Cam profile: the inner envelope of the roller circle (radius 8) moving along the pitch curve, i.e. the pitch curve offset inward by 8 along its normal (base circle radius 30, maximum radius 44). The profile is extruded from Z=0 to Z=15. Hub: Ø34 from Z=15 to Z=25 on the cam axis. Bore Ø16 through Z=0..25 with a 5 wide keyway on the 270° side (phi = 270°), full length, floor 10.3 from the axis.
