Group,

A typical CNC controller operates on Gcode programs in what would be
called an interpretive mode. As opposed to having an already
compiled CNC program to work from
My question is, why don't controls have an option to pre-scan a
program and by accessing the tool and part offset tables pre-calulate
all the cutter paths so that when actually cutting all the controller
has to do is deal with interrupts and motion control? Or do some
controls have that ability
Any thoughts?

Thanks,

Doug,

I was looking at how the Aerotech guys had their CNC
set up and found they use an "engine" that requires the code to be compiled first. They could use a high level language sorta like C? G code or one more. You could mix the different languages in the same program. Compile this and run the finished code. Supposed to be real flexible. I was concerned with having to recompile everytime I needed to tweak a program. I guess it is OK for a production run but for one offs, it'd be too much work.
