Haas Decimal Point Default to Float Setting 162

Haas decimal point setting, this  is really important on a CNC Machine.

When set to on when you type in X20 it adds the decimal point for you.

If this is off when you enter X-2 then you would get X-.002

If you had the setting on then you would get X-2.

The following letters would be affected.

X, Y, Z, A, B, C, E, I, J, K, U, W

It doesn’t really matter how you set this but It’s really important. You might think it’s much easier to have it on so you can just type in X2 and you get X2.

Now this is a really bad habit to get into. The reason is that if you ever work on another machine where it needs the decimal point.

So you type in X2. and you get X.002

Now you are going to be in very deep shit. If this is a CNC lathe then you will probably have a collision and you might shit yourself too which can be unpleasant.

Haas Decimal Point

This is a setting on all Haas and Fanuc machines and you can never be sure how the machine is set up.

This is how you set it on a Fanuc control.

We really love you but honestly we don’t really care if you break your machine. However if you do, make sure you youtube it. Then you could make a shit load of money from the video.

Oh yea we do CNC Training too, not to mention Classroom Training.

Haas Jog Spindle Speed Setting 98

Haas Jog Spindle Speed

This article tells you how to control your Haas Jog Spindle Speed

Are You Jogging Too Fast

OK so this is not some fitness weight loss type blog

“Lose 3 stone in one day”

We all know that’s not possible unless you’re at the zoo and a lion bites both your fuckin legs off.

The CNC Training Centre Diet

Anyway I am one of these blokes that loves tinkering with things. I’ve never actually killed myself (otherwise I would be posthumously writing this article) but I have come pretty close on numerous occasions.

The other day I realized you could control the jog speed of a Haas Machine by setting parameter 98

I was so excited I just had to play with it (no sexual innuendo intended).

Normally I don’t bother using SPINDLE JOG because it spins the part too fast.

Here’s how you change setting 98.

Press this button………

Sorry it’s a dirty grubby button but it’s the only one I have (welcome to the real world)

Anyway I’ve no doubt yours is probably dirtier than mine.

Type into setting 98 the speed you want when you press the SPINDLE JOG button

Set it to 10rpm, it’s nice and gentle if you want to rotate your part and see what’s going on.

Enjoy

All you need do now is enjoy it.

First press MDI then press SPINDLE JOG

Caution

You can do it with the door open too so be careful.

How to Limit Wear Offset Input on Haas Machines

Haas Limit Wear Offset Input

This article tells you how to limit wear offset input on your Haas Machine.

Collisions should be avoided at all costs on a CNC machine, so anything you can do to prevent them has got to be a good thing.

There are many things you can do, like paying careful attention to the way you prove out your program.

When run a programme that has already been proven, you know the actual CNC code is fine.

So you have two things to worry about.

1. Is the WORK SHIFT or WORK OFFSET correct?
2. Are the TOOL OFFSETS correct?

These are the two things that you control and they link the programme to the machine.

It would make sense therefore to check each tool change. Check the point where it first approaches the workpiece.

Once a programme is running we only need to go into our prove out mentality when we change the programme or the tool wear offset.

When we adjust the tool offset we can either adjust the Geometry or the Wear. Now it’s always best not to touch the Geometry. That’s because it’s a big number and big numbers can hurt you.

Lets say this number was 200.986 and you wanted to move it by 0.116

Not too difficult but it would be quite easy to alter it by  a large amount and not even notice.

Then you could be in trouble.

Now if you always use the WEAR you know it’s always going to be a small amount. So if you see a large amount in the wear column you can go into a mad panic.

What’s The Point of All This Where’s He Going?

So if you always use the WEAR and not the GEOMETRY you’ll be ok. Unless of course you were stupid enough to put a big number in the WEAR

or…….

Against my advice you alter the GEOMETRY.

Help Is At Hand (limit wear offset)

On a Haas Machine you can limit wear offset amount in a your settings.

It still lets you do it but gives you a sarcastic little warning.

Press this button

Sorry it’s a dirty grubby button but it’s the only one I have (welcome to the real world)

Type into setting 142 the maximum amount you want to limit wear offset input by.

Now if you try n exceed the dose, this is what you get.

Note

This limits the amount you can add to your offset not the total amount of the offset.
