I have been working on a system for making multi tooth wheel and pinion cutters. My goal has been to make them quickly yet accurately. There are several ways to go about making these and I have researched many books on the subject (not all I am sure).
Even though I have had little experience making cycloidal form cutters there was always something nagging at me about the process of figuring out the exact cycloidal form and achieving that in a cutter for a specific wheel or pinion. I did stumbled across one book that has slowed my head from spinning.
The book is "The Clock and Watch Makers Guide to Gear Making" by Robert Porter
In his book he has pre-calculated gear set (wheel and pinion) cutter measurements and given quick references. Along with gear set and cutter design sheets (just plug in the #'s). These quick references provide cutter width at minor diameter, cutter radial flank angles, cutter profile length, form tool radius, cutter working depth, ect...Some ideas and designs for tooling and much more.
Another book I have thumbed thru many a time is Malcolm Wilds "Wheel and Pinion Cutting in Horology".... a fantastic book and well worth it for many reasons.
I cant say enough about anyone who spends the huge amount of time to compile these types of books for us to learn from...
At this point I am following Robert Porters methods and sprinkling in a plethora of ideas and methods from everyone else.
I have reason to believe this process can be used for making cutters for watch gear sets, ratchets, escape wheels, ect...with some imagination.
Have a great day.
William
