Milling an angle

I am trying to mill with a ball mill, but to avoid the line it leaves in the middle of the groove, I want to mill at an angle, 17 degrees to be exact. I made a set of parallels with my plasma cutter to set the stock at 17 degrees. According to my calculations, z needs to travel 9.934" and z needs to travel 2.904". I need the z axis to move at a slower rate than the x axis. I have been trying to do this in BobCad, but I'm just learning how to use it, and havent figured it out yet. Is this possible to write out manually?

A buddy of mine said to look into interpolation... if you guys have any info on interpolation, it would be very helpful :)

You don't say what control you have, but most CNC mills have G01 Linear Interpolation, which will "interpolate" a straight line from the current position to the commanded position. Most also have G91 Incremental Positioning mode, which specifies that any axis command that follows will be a distance rather than a position.

G00 G90 X0 Y0
G01 Z0 F20.
G91 X9.934 Z-2.904
Y0.02
X-9.934 Z2.904
Y0.02
X9.934 Z-2.904

aaaahh, ok I believe I get it now. I know my machines support linear interpolation. I figured that both axis would travel at the same feed rate with G01, so I figured wrong. Thanks :)
