Need Help!- Bar Face Arbitrary Designs. X, Z, C, I, J

[sfilippo]

Hello,

This question relates to generating G-Code from BobCAD/CAM 21 set in absolute using X, Y, I, J where Y will become C after editing and Z will be added for depth of cut for each line/arc segment in Bar Face.

The machine being used is 2007 Mazak Matrix Nexus with Live Tooling CNC Lathe with X, Z, C, I, J (no R selection in Mazatrol mode) capability. (no Y axis either)

The idea here is to make Personalized Coins by engraving designs on the Bar Face, then part-off desired thickness. Using a pocket style collet, remounting the disc and engraving another design on the back side, producing a two sided custom coin.

Mazatrol Option is far too tedious for this project. ISO G-Code loaded thru USB port will be much faster, I think.

Okay, the coin will be 2" diameter.

I'm puzzled about the C axis coordinates coming from my CAM program's Y.

If there are 360 degrees in a full circle, and I'm making a design with geometry in all directions on the bar face, where would I place my design at on my CAD grid?

I have it dead center at the moment and I'm waiting for the light to come on so I can start generating G-Code.

Maybe I should shift the design to PositiveX/NegativeY Quadrant? Then change all of the -Y coords to C and move the decimal two places to the right?

Anyway, I hope I've explained myself well enough to get an answer back.

Also, I've noted above that there is no (R) Radius selection in Mazatrol mode programming, but I do have I, and J in that mode, so I assume I, and J without R will have to be part of my G-code format. (G02/G03 interpolations)

Thanks in advance.
