Positive Return Cam Mechanism
grabcad
A Cornell Library model (http://kmoddl.library.cornell.edu/model.php?m=238) features a Reuleaux triangle for generating intermittent/reciprocating movement. After publication, similar models by Nevres (https://grabcad.com/nevres-1) and Ferro (Positive Return Cam) appeared. Created using Solidworks 2015, the model was rendered with Simlab Composer 6 Mechanical Edition and edited for frames in Virtualdub before being saved as AVI/X264 and BMP. MyMP4BoxGui remuxed the video to MP4 while PhotoScape generated GIFs. IrfanView was used to edit renders, and Simlab Composer 6 files are animated. ZIM files open on iOS and Android devices with the free Simlab Viewer app, and models are available in various formats including Solidworks 2015, Simlab Composer 6, DAE, STEP, IGES, Parasolid, OBJ, 3D-PDF, SketchUp, 3DS, and ZIM.
