Hi, I would like to be able to cut arcs with my CNC, I have a few wizards that can cut arcs but they always ask for the radius of a circle and that is not exactly what I need.
What I need to do is to cut an arc out of boards of different size:
Ex. Let’s say that I have a board of 72" long by 6"wide and would like to cut an arc of 2" to be able to reach both ends, the radius for this setting would be 325" radius, my table is to small :confused:
Am I missing something with the wizards that I have or is there other ways or wizard to do this?
To mention a few of the wizards that I have: The wizards that comes with Mach3 and a registered version of Newfangled solution and a few others.
Thank you for your help

do you have a MechMate? Cad software? Cam?
Here's a free cam software that works well for simple things...

Mars,

Give us a better idea of what you are trying to do.

You can still draw what you need in a cad program but only cut the 72" board.

I have made some radius that are 15' and 25' but I cut them out of a 12" and 24" board. It is a very shallow concave dish.

I'm building an entertainment cabinet and the top rails have a slight curve in it (shallow concave dish).
Is it possible to do, If I use a standard arc wizard or do I have to use a cad program to do this, I only have Corel Draw.
Thank you for the reply

I don't use the wizards... Nut the cam process is where the greatest challenge for me is...

I dont know much about the ability of Corel, but if you can get hold of a cad package you will be able to create your section of an arc easily. If you cant come right, send me the requirements of the panel and I will draw it up for you and send you a dxf, you should be able to take that into corel and work from there. I know Kobus uses Corel, maybe he can chime in here?
