From the TNC155B manual we have:
"Before machining, the program can be subjected to a test for geometrical errors, without machine movement. The control calculates the program sequence as per a normal program run." (and also, just like a graphics run, it stops at every STOP and every tool change as well).
As we understand it, all this does is check that the machine doesn't think it has gone outside limits. Machine builders often set MP to their max, so this is only of any use if you manually set the MOD limits for XYZ each time - and it can't take any account of fixtures etc., nor does it know the whereabouts of the uncontrolled axis (e.g. knee). All we do is check it in PartMaster before we send it to the machine, then run it in graphics - but in both cases it is the human ("mark 1 eyeball" !) that is doing the real checking - I would never rely on the Program Test button to be definite that the program was safe (although if you're using Parametric programming, it could be a useful extra check).
