Operator interface issues...

[REVCAM_Bob]

Fadal machines have the macro capability of asking for user input such as
Please enter the size of the hole:

Then based upon that input, adjust a cutter diameter and re-run a program.

It is my understanding that Fanuc controls do not have this capability to request user input, and I am wondering 1. Why not and 2. Does anyone have
experience with alternative interfaces i.e. exporting interface out to a p.c.
etc.?

The only way I can suggest is to use the macro variables.

Pre enter the variables in the 100 or 500 ranges before starting the program
or
MDI a macro call that supplies the parameters on the MDI line
or
put a program stop in the program with a comment/instructions to edit the macro variable before restarting

In all cases I would suggest as much error checking as you can manage to program in it.
