Hi Dave, as RC mentioned, we also generate our sprocket details in MasterCam. MasterCam has a bunch of user applications (.dll) called chooks that you can use to make sprockets, gears, and other things that I don't know much about. The sprocket profile generated is ANSI standard but is only a 2D profile. Because we have to use a 1/8" endmill to cut 25 tooth spockets, we either have to make several 0.000 clearance passes or one really slow clearance pass. The endmill flexes too much and it makes a difference in fitting the chain.

RC, really? There is a sprocket generator for Solidworks? My biggest complaint is that I have never found one. Where is it located, or is there some sort of add in? We would love to be able to generate sprockets in Solidworks. I know that Inventor has something.
