Macro variable example I programmed today.

[theemudracer]

I am still in the learning stages of this. I am interested in your opinions and suggestions.

let me explain a little before you look my prg's over.

It is for a Lathe with a subspindle. There are 3 different part prg's below that use the same sub program O9983.

The parts are 1.25 o.d. with a .750 I.D. hole (that I drill from solid stock) with varying lenghts and tolerance on the I.D. .

I am using a parts ejecter inside the subspindle that has a limited stroke of .875 . That is the reason that I had to set the G55 Z value depending on the part length Using the #500 variable.

Let me know what you guys think of it and suggestions please.

thanks
Jon

theemudracer:

I have only glanced at your code, but I might do this:

Program 1

#510 = 3.125 (length)
#505 = 0.0085 (X OFFSET FOR DRILL)

M98 P9900

M30


Program 2

#510 = 2.500
#505 = 0.010 (X OFFSET FOR DRILL)

M98 P9900

M30


Program 3

#510 = 2.630
#505 = 0.016 (X OFFSET FOR DRILL)

M98 P9900

M30

This makes the main calling programs simpler, and easier to see what the real variables are.

Then you may also be able to use

G65 P9900 Z3.125 X0.0085
or
G65 P9900 Z2.500 X0.0100
or
G65 P6600 Z2.630 X0.0160

instead of the #-variables. Where Z value is length and X is drill offset. Other address letters can be used. See HAAS manual under MACROS.
