Re: [CAD_CAM_EDM_DRO] Cool Worm Gear

Bill, I think you misinterpreted my question. Calculating a gear diameter
is easy...I wouldn't even need to look at a book or a formula for that.

From what I've seen explained (or explained improperly, just plain poorly or
not at all) so far' it would appear only one size of gear blank could be
cut.

No one has yet even tried explaining what position (plane) the gear blanks
are mounted in, how they are rotated to cut the teeth if the spindle
holding the tap is rotating, or anything else that is REALLY CLEAR. So I'll
ask again:

1. In what position do you mount the gear blanks?
2. Is the bore mounted parallel or perpendicular to the long axis of the
lathe?
3. Are the flat sides of the gears mounted parallel or perpendicular to the
horizontal surface of the crossslide?
4. Since the tap has been indicated as being mounted in the spindle and
supported on the opposite end by the tail stock, is the tap actually turning
while the teeth are being cut?
5. I assume you are somehow cutting only one tooth at a time here? What
prevents a rotating tap from destroying adjacent areas where the following
teeth would be cut?
