Hi TP
 Thanks for the input.
I like the simple code ,and the idea of a linear x axis  makes the math way easier.
not sure how the Wizards work but I will check it out.
Thanks again for the input.

Hi Craig
thanks for the quick reply
I understand I could do this with a regular burning table ,but the torch or tip not square or perpendicular to the material  for some reason you end up with a hole that is oval or trapezoidal. I need to have the holes perfectly round. the hole can be tapered or beveled but it has to be centered and round.

I have been thinking maybe the angular arm should be made as a linear axis , this would make the machine foot print larger, but less math.

Chad

General Mach Discussion / New burning machine idea

Hi all .
I am new to the Mach forum and am looking for input on a new machine idea.
 I would like to build a machine for flame cutting circles in round steel plate. the plate is up to 3" thick and usually has an ID hole.
the machine would look something like a record player. With the plate being the record and the needle being the torch.
this would mean the axis would be the rotation of the plate and the angular movement of the arm carrying the torch.
this way the rotation of the plate should make a very round and accurate cut.

So I guess my first question is can Mach be configured to work in this way? there really isn't a x axis or y axis, they would both have to move if you were to try and make a straight line. The axis would have to be calibrated in pulses per degree. and if I wanted to cut a hole from 3" to 6" could a macro be written in Mach to do the trig to figure out the angular movements, and  maintain a constant surface feed of the torch as it moved from the small diameter to the larger diameter?
wow I can see a lot of math !
Regards
Chad
