Art has created a slick program to generate the code to cut gears on the mill. It is called Gearotic Motion......it's a slick program.
Do an internet search for the site.

Somewhere in here   I posted  a spread sheet that calculates the dimensions for drawing any gear in CAD.
So what one can do is select a gear and comparitively find the nearest matching radius to make one....great trick for making small gear cutters.

hi rich
thank you for your reply
here is a post i found to make a form cutter for the lathe, I was trying to get the fillet wizard to cut the radius's on the shaft. it cuts the right side as your facing it fine but I cannot cut a radius on the left side.

The txt doc opens in wordpad

the tool then will be milled and relieved to work like a hob but with just one row of teeth

I have just started with cnc and I know no g-code I'm using wizards to start with some really good results. I can make this by making the cut in the middle of a longer shaft doing one side then inverting it in the collet and finishing but I would like a way to cut the radius on the left side without removing the shaft from the collet I purchaced both mach and new fangled products I dont know where to update  I'm new to forums also so I get
lost easy 
thanks for any help   
ps nice job on your fly cutters that looked like it worked well too I did them by hand under a magnifyer  worked ok
this Idea I have should produce a full set of cutters for however many teeth that will last a long time

Why not do the forming as shown in the article?
You can generate the code using LazyTurn but you will need to have a dxf file with the profile.
Looking at the turn wizards, seems they only provide for turning the radius on the tail side of the piece.

the article would require a tool for every range to be made myway would be so easy i'm off to find a user wizard that will cut a radius from both directions someone else has to have had this come up.

I guess I'm going to have to learn lazyturn too   ....
good thing this is a hobby they would be cutting my pay if this was my living lol
thanks again

All the Turn wizards that i am aware are listed in the following thread:
http://www.machsupport.com/forum/index.php/topic,17103.msg116309.html#msg116309

Wizard 2 & 16 in the pic Flyout Modified HCIR would probably do the trick but they are modified wizards that need to be tested.
I didn't do the mods and not sure just how far the mods went: ie; they post comments, work in radius and diameter mode, some are new, etc.

If you find something let us know,
