Messing With Parameters Can Be Fatal!!!!!

Offset Keylock Fanuc Parameter, before you change this you will need to go to the setting screen in MDI.

From here you can allow yourself to alter parameters.

Put a 1 in the parameter write box.

Today we are going to change the parameter that stops operators from altering wear offsets.

Apprentices should be inquisitive it’s normal. We want them to experiment and learn by making mistakes.

Mmmm sounds great but and there is a big but. By a big but I don’t mean a big arse I mean but with one t.

I once trained an apprentice on a Haas VF1. He picked it all up really fast. When I revisited he was really excited to show me how  he’d learned to alter parameters all over the place.

It was real scary stuff he thought it was fuckin space invaders or some computer game.

Game Over

Game over on a CNC machine means you just buried a tool in a part and caused £5000 worth of damaged or somebody just died for real.

The key switch is now needed.

Parameter 3291 will stop operators from changing the tool wear offsets. It requires use of a physical key to unlock them.

So you just pull the key out and depending how the machine is setup It’s like you just made him wear boxing gloves.

So in Parameter 3291 you can set bit 0# (WPT) to a 0 and you will need to use the key to edit offsets.

Isn’t it just great to sort out those annoying problems?

By the way it wouldn’t have stopped my rogue apprentice I think he’s the MD now.

That’s it away you go, Offset Keylock Fanuc Parameter

Oh just one other thing before you go off and cripple your machine forever.

Do yourself a favor take a picture of the screen before you change a parameter. If you aint got a camera then you must have a piece of paper.

Even better back everything up.
