scad script for some basic cam profiles updated v0.2c adds internal cam types and fixes a minor bug in the hypo and epicyclic profiles updated v0.2d added a few more types render times much improved over version 0.1 and is a complete rewrite still a some more profiles to add before its a complete lib function NOTE you may need to set edit>preferences>advanced> turn off rendering at value to 256000 in order for them to render correctly openscad 2013.06 definable profile shape , radius, profile depth ratio, surface steps , number of lobes , height, twist ,twist slices , shaft hole size and type read script comments for instructions provides :- Cyclic_Cam(profile_type,r,phr,sa,nt,h,tw,sl,hole_type,hole_size,pd) Internal_Cyclic_Cam(profile_type,r,phr,sa,nt,h,tw,sl,pd,rim,atol) Cyclic_Cos_Cam(r,phr,sa,nt,h,tw,sl,hole_type,hole_size) pure cosine cam gear generator for use with a knife edge point of contact Cyclic_Pin_Cam(r,phr,sa,nt,h,tw,sl,hole_type,hole_size,pd) a cosine function cam for use with a roller/bearing (with a diameter of pd) as point of contact Cyclic_Hypo_Cam(r,phr,sa,nt,h,tw,sl,hole_type,hole_size) a pure hypocycloid function for use with a knife edge point of contact Cyclic_Epi_Cam(r,phr,sa,nt,h,tw,sl,hole_type,hole_size) a pure Epicycloid cam function for use with a knife edge point of contact an extra test module is included Cos_Cam_test(); draws one of each type of cam as per main picture Cyclic_Cos_Cam(red) Cyclic_Pin_Cam(green) Cyclic_Hypo_Cam(blue) Cyclic_Epi_Cam (yellow) (this may take an hour or two to render)
