I'm a technical writer who uses Solidworks to work with client models, ultimately to produce graphics from Composer. So that I can support my clients when the need arises, I am working on creating blocks that will act as "gear cutters" when I need to model gears using the following youtube video as a guide:
https://www.youtube.com/watch?v=uj7BnldaOSc
Note that there is a problem with this method when creating gears with over 105 teeth as the angle determined by 360/(4*"N")-"alpha" goes negative at 106 teeth. I have a work around that produces gears with greater number of teeth, but am not sure of its accuracy.
My question is, does anyone have a suggestion for information in creating gear cutters, such as their cutting profiles?
I searched the Internet and get a lot of results for gears, but not the cutters. I understand that the gear cutters come in sets and each individual gear cutter can cut teeth for a specific tooth number range. I would like to know whether my output reflects actual cutter profile. When I produce gears, using the method shown it the video linked to above, the teeth don't appear to mesh as neatly as I expected. Ivan Law explains this in his book "Gears and Gear Cutting" as the portion of the involute used changes as the tooth number changes. I want to be as accurate as possible.
Thanks, Jeff
