cyclic cam scad (lib)/script

thingiverse

The updated SCAD script offers various cam profiles, including internal cam types, fixed in version 0.2c. In version 0.2d, more cam types were added with improved rendering times compared to version 0.1. However, there are still some additional profiles to be included before it becomes a complete library function. It is necessary to disable rendering at a value of 256,000 in preferences for correct rendering. The script defines cam types such as Cyclic_Cam, Internal_Cyclic_Cam, Cyclic_Cos_Cam, Cyclic_Pin_Cam, Cyclic_Hypo_Cam, and Cyclic_Epi_Cam, each with specific parameters like profile type, radius, depth ratio, surface steps, number of lobes, height, twist, twist slices, shaft hole size, and type. The script also includes a pure cosine cam gear generator for knife-edge contact, a cosine function cam for roller/bearing use, and test modules to draw various types of cams. Note that rendering the test module may take an hour or two.
