Hi.
Can anyone tell me if it is possible to machine an oval, outside dimensions 125.4mm x 94mm on a heidenhain TNC145c? Cheers.

Can you scale inividual axes ?

program a 94mm circle
scale the X axis up by 1.33404 (125.4/94 ), leave the others as 1.0

PS---program the circle seperately, and around X0Y0 to make it easier

Oooh thats cunning! I see what you are doing there.
Er... i dont know. I will have a look at the parameter list and see if i can do anything in there.
Thank you.

Cant find anything in the parameters that i can adjust. Any other ideas? I have a feeling it could be done with "rnd" function but i am not sure.
Cheers

Pity, would have been easy if you could

CAD-CAM avialable ?
If it is, you could do a circle and scale the X-axis to get an oval and then apply a toolpath to machine it
