oscillating z....

hi all

i need to find out an easy(hehe) way to make my cutter move up and
down slowly, 1-2 strokes every minute, while it cuts squares,
circles, ellipses or whatever, to get an even wearing of the tool
(diamond) and to get a streak-free finish with the polishing tools
(flexible resin bond) is there any code(macro?)for this purpose, i.e
turn on z-oscillation at the start of the prog and turn it of at the
end.


(i cut out and hone/polish sinkholes in granite and marble
kitchen/bathroom tops)
