Say you have a 100 orders for shaped punches on your desk each for 1 or 2
parts with cycle times of around 5 minutes, the only difference between
them is the shape (obround, rectangle, hex, octagon, etc.) the sizes, and
the orientation of the shape on the punch.
It is a lot faster to have a person stand at the mill, edit a few variables
and run the program then it is to go the CAD/CAM send program to the
machine route. And it is a lot easier to train the machine operator to set
variable
X1 to the shape number
X2 to the width
X3 to the length
X4 to the angle
then it is to train them to efficiently run CAD and CAM programs. Then if
the CNC program does just a little sanity checking on the values entered
you can all but eliminate crashes, a simple tool length touch off switch
will stop most of the rest.
Plus you do not need to have all those licenses for the CAD and CAM
programs along with the yearly maintenance contracts and a fast enough
computers all sitting by each mill which if you have 20 or 30 mills adds up
to a lot of $$$ even if 2 or 3 mills can share a computer.
Is the reason for macro B and parametric programming on CNC machines.
And since I am used to that type of programming at work that is the way I
will do it at home. :)

I guess it depends on the type of work you are doing.
I see these types of tranforms being handled in the relm of the cad/cam
application.
But for drill circles or other canned cycles I can see the utility.
Perhaps I could have saved you some time over the weekend. I have already
written a
program the can rotate g-code. I have not tested it for all cases, but it
has worked
for the basic g-code that I do.
I'll post a link to it as soon as I get it up on my website.
