Using macros for varying stock height or other method?

[JB7280]

Not really Mastercam related, but I have a part that I'm working on, where the stock has been varying anywhere from 1.5" to 1.75" and everywhere in between.   At the moment we are forced to take what we can get, as we can't wait for these parts.  For the first side, I am probing Z, facing the part, and qualifying the outside.  For the second side, I am using a highfeed mill to face of the excess material.  Dynamic pass from the outside, spiraling in towards the inside, stepping down in Z with each pass.  I'd like to probe Z to add extra passes when necessary, and remove air cutting when it's not necessary.  I believe this could be done with a macro, but I'm not quite sure how, and time is of the essence at the moment.  Would any of you be able to steer my in the right direction about the simplest way to get this done without having to manually adjust every time?

Here's a quickly created Macro that you can look at.

Note: Use this at your own risk. This was quickly made and not proven out.

 

O???? = Facing subprogram

#699 = ? (Z top of stock)

#700 = ? (variable Z top of stock)

#701 = ? (Z bottom pass)

#702 = ? (depth of cut)

(PROGRAM)

#700=#699

G00 X Y G54.1

Z[#700+.1] H1

WHILE[#700GT#701]DO1

IF[#700-#702]LT#701 GOTO1

G00 Z[#699-#702]

M98 P????

G00 Z[#699+.1]

#700=[#700-#702]

END1

N1

G00 Z#701

M98 P????

G00 Z[#699+.1]

Awesome, thanks.  I'll try laying that out and applying a probing routine to it and see if i can make it work for what I need when I'm back at the shop.
