I made a head for the Shaper that holds the Gear cutter.
So are you:
1. Grinding a custom cutting tool to match the module of the gear and simply down-feeding to depth for each tooth, then rotate the dividing head to the next tooth? (I have heard this is very hard to do in anything but plastics and maybe aluminum due to the cutting tool acting as a form tool and the cutting forces around the entire cutting edge are huge.)
2. Grinding a custom tool to the pressure angle of the gear (i.e. 14.5 degrees) and using the table feed and a linkage to rotate the dividing head at the proper ratio to follow the involute cutting path?
(this makes the cutting tool act like a threading tool and only cut using a small section of the tool as it pivots though the involute cutting path.)
Hard to explain, but there are many YouTube videos.
Thanks, Mike -
I mounted the block that (sandwiches) holds a gear cutter and just uses one tooth of the cutter.
It (The gear) is held in place with a Dowel pin.
I made an extension table with holes centered with the slots the width of the plate.
