multiple shape milling levels was created by Segitarius

Hello

I contend with following problem:
I try to write a program that mills some shape around with few passes. Each passage makes my mill work deeper in "Z" axis.
Now I am doing it this way (unprofessional in my opinion):

...
N4.... G41 etc...
N5... Shape
N6... Shape

z-1

shape

z-2

shape

z-3

etc...

Is there some more professional way to write a program for milling in multiple passes? Like sort of canned cycle or some g code... ?

Any help will be appreciated

Konrad

Hi

Have a look at JT's gcode tutorial
www.gnipsel.com/linuxcnc/g-code/index.html

Such a thing is easily done in a conditional loop
eg

#<_cut_depth> = 10
#<_current_depth> = 1

	o100 DO
		G0 Z-#<_current_depth>
 		shape
 		#<_current_depth> = [#<_current_depth> + 1]
	o100 WHILE[#<_current_depth> LE #<_cut_depth>]

regards
