SL30 want to single point broach grooves

[XYZ machine]

Ok i have several large bushings made of 52100, I need to single point broach 6 longitudinal grease grooves in each one. My question is I don't want to hand crank them in on a manual lathe, can I make my SL30 do it? I know how to make the spindle index but I can seem to figure out how to get the z to feed with a stopped spindle!! Any one ever tried to do this? Sure would be a bunch easier on the old arm! These grooves are 3/16 wide x .090 deep thats serious arm pump now!!

Hook me up guys !!!

G98 = feed per minute mode - works with spindle on or off

G99 = feed per revolution mode - spindle must be on

mike i think I had tried that and it did not move maybe I am missing something. how about an example, maybe I missed something in the coding.

Thanks,

Include this code in a program..

S500
G98
G01 Z-1.0 F10.0


I tried this on an SL and it worked. It insisted on having an S value, even though the spindle wasn't turning. I don't know why.
