Offset Keylock Fanuc Parameter 3291

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.

Offset Keylock Fanuc Parameter

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.

When counting the bits in parameters you count from right to left so the first one on the right is bit 0 or sometimes known as #0

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 favour 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.

Retain Geometry Fanuc Parameter 5003

Messing With Parameters Can Be Fatal!!!!!

Retain Geometry Fanuc Parameter 5003, to change this parameters first you need to go to the setting screen in MDI.

Put a 1 in the parameter write box.

Today we are going to change the parameter that stops your tool offset from being dropped when you press reset.

Retain Geometry Fanuc Parameter

Parameter 5003 will stop that annoying thing where you activate a tool offset and then press reset and it clears.

If you have a Mazak machine you will know that if you index to tool 6 the offset will be instantly activated. This means if you are on a CNC Lathe you can just move the tool to a 50mm diameter and turn away. Providing the tool has been measured the size will be correct.

Retain Geometry Fanuc Parameter 5003

You are probably used to the tool not being active if you use a Fanuc control but help is at hand.

With this parameter 5003 set to 1

You input T0101 in MDI and that activates tool number one’s offset. Your position display is now correct (allowing for tool geometry).

If you now look at the ABSOLUTE position display and press reset it will not change. If it changes then the machine is more than likely dropping the tool geometry.

#6  (LVK) Set to 1 not cleared on reset

#7 (TGC) Set to 1 not cleared on reset

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

Power Up Fanuc Parameter 3402

Messing With Parameters Can Be Fatal!!!!!

Power Up Fanuc Parameter 3402. To change parameters you need to go to the setting screen in MDI. Now put a 1 in the parameter write box.

Today we are going to change the parameter that sets all the modal G codes when you first turn on your machine. This is often known as the wake up state.

Power Up Fanuc Parameter How it works?

When you switch on your machine certain G codes will be active. But what G codes are active?

Well….  they are whatever you set in this parameter.

Imagine you just typed in X50. Y50. in MDI and pressed cycle start. Would it rapid, feed or try and go around in an arc?

In parameter 3402 the different bits set the G codes that are active when you first turn on your machine.

#0 G01 (Set to zero you wake up in G00 set to 1 you wake up in G01)

#1 G18 (Set to zero you wake up in G17 set to 1 you wake up in G18)

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

Things like the machine waking up in incremental can be a potential disaster.

Subroutines Fanuc Parameter 6005

Messing With Parameters Can Be Fatal!!!!!

Subroutines Fanuc Parameter 6005, to change this parameter you need to go to the setting screen in MDI.

Put a 1 in the parameter write box.

Today we are going to change the parameter that allows us to use local subroutines on your Fanuc control.

To call a subroutine on your fanuc control. You first need to make sure that Bit 0 (SQC) of parameter 06005 is set to 1

(See yellow square.)

Subroutines Fanuc Parameter 6005

Oh and before you get over excited this option is only on newer controls.

Doing it on a Siemens control

Local Subs Fanuc Parameter 6005

A local subroutine is where your sub-programs are included in your main program.

Programmers like to do this because it makes programs very easy to manage. Heidenhain and Siemens controls all have this facility.

Early Heidenhain controls only had this internal way of using sub-programs.

External Verses Internal

External sub-programs are separate so effectively you call one program from another.

The good thing about a separate sub-program is that you can call it from any of your main programs.

This means you could use it to send your turret on your CNC Lathe to a convenient position for tool changing. When you want a safe tool change position in any of your programs you can call this up and know it works.

Siemens controls are very versatile when it comes to sub-programs and they are really easy to manage.
