multiple shape milling levels

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

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

Thank you
