Hi Phil:

  There should be absolutely no difference. One couldnt use the ball section as its not the right shape,
so youd end up having the ball interfering in the root by th etime you lowered the tool enough
to get the flat section to touch the tangent..  :)

I see that now. On my low tooth count gears the base circle is well above the root diameter, so aI guss a bullnose might work. Whereas for larger tooth counts the base circle can even be above the root diameter, so as you say not enough room for the bullnose. But can you not use a bullnose and allow the root diameter to lay where it falls?

Well you could.. but it depends again on the toothcount.. if the root is above the base
then youd create trochoids below the root.. might be nasty in some instances..

I do in some things put the bit where I have to and if the root bottom gets gouged..so be it..
but I hate to push that theory too far.

I have decided after all this to make a simulation
on screen so I can watch the damn thing cut in real time.. :)

Hi Art, is this simulation going to be made available to Gearotic users,..........pretty please. I did think about finding me a 3D simulator that I coud use but it would be very nice all in one package.

Phil:

  Hard to promise anything there, simulators for things like this are very hard which is why they tend to be very expensive. If the hardness doesnt kill me then yes, Ill include it..otherwise Ill end up using it internally for verification.
