Need help with programming a spanner wrench - CNCzone.com-The Largest Machinist Community on the net!

I have a bridgeport interact II with a Heidenhain controller. I dont have a spanner wrench for the kwik switch collet. I dont have the money to buy a wrench either so I thought I would carve one out of some metal I have laying around.
Can anyone help me out with the programming?
The diameter of the kwik switch collet is 2.55"
I need help with the arcs or circular interplation.
I can weld a little rectangle piece to fit in the groove of the collet so that part doesn't need to be programmed.

Can you give me some more information? I have a lot of CAD software and can create programming code for lots of different machines. If you give me all the Dims I can probably help you out.

Here is what I came up with. There is a little piece missing from the drawing. I'm going to TIG weld it on later.
Thanks for the help.

I figured it out.
You have to tell the controller where the circle center is then program the arc end coordinates relative to the circle center.
AND! this had me stuck for a while, you can't have radius compensation on, meaning you can't have RL selected, at the begining of the arc movement.

Sounds like you have it under control. Do you need anymore help? Sorry I didn't get back top you sooner.

Cutter comp won't work on an arc? I know most machines need cutter comp engagement/disengagement to be on a straight line, but going from a straight line to arc wont work?

Can you incert a command at the end of the line before the are to trun off the radius compensation or deselect the RL in the program?

What is the model number of the heidenhain control?

The control is a TNC 151 I think.
