Heidenhain Programming Examples

  • The control has been around for a long time and is fitted on many machines.
  • It has improved with age as more and more useful features get added.
  • This is a control that can be learnt quickly and easily.
  • It is a control that can be used on many levels and has some very sophisticated features.

The problem with learning something quickly and easily is that lots of good features are missed.

I often say to my customers “I get paid to read the manuals you can’t be arsed to read”

Obviously I wouldn’t say “arsed” to my customers. I’d say something more sophisticated like  “the manuals you don’t give a flying fuck about”

I hate to see things underused we are The Wombles of CNC Programming. Check out this article.

You know, like when you find a piece of cheese behind the fridge. My mother taught me that so long as you cut all the mould off it’s fine to eat.

Most of the buttons will look familiar if you worked on older controls and you come to the newer models. Don’t be fooled by this there is loads of new stuff lurking under the bonnet.
It has a parametric programming function using Q defs.

“Bloody hell what are they” I hear you say.

It’s ok it’s just me trying to be posh again. It means that you can control a programme externally. The sizes, feeds and speeds, all sorts of stuff can be changed each time the programme runs.

(1) Here is an example of how to use the various arc commands on a Heidenhain control.

You can programme circular arc moves in four different ways on this control.

“Why would I want to do that sounds complicated”

Actually it ain’t. The idea is you programme the same as your drawing.

  • The drawing gives me sharp corners. Use this button Heidenhain Programming Examples
  • The drawing gives me the centre of the radius. Use these two button.Heidenhain Programming Examples
  • My line is tangent to the circle. Use this. Heidenhain Programming Examples
  • End point and radius?  This buttons for you .Heidenhain Programming Examples

How To Format a Data Card on a Fanuc Control

Format a Data Card on a Fanuc Control yes that’s what were going to do. Now first of all I have a confession to make.

People often say to me how nice it is of me to write all these articles helping people with the shit they can’t do. Well sorry it’s not true actually I’m just a selfish bastard just like all the rest of you.

My only reason is that I have and always have had the memory of a goldfish. If you have ever had a goldfish and tried to train it (which I once did). I read books on it like “How to Train Your Goldfish in 3 Easy Steps”, for which I got a refund.

 

 

Anyway I digress. The reason you can’t train them is, not least of all because you can’t keep them out of the water too long, but they don’t remember a word you say. Fuck all, Jack shit.

So the minute they learn a nice trick they immediately forget it. It doesn’t bother them because they just forget that it bothered them.

Sorry no more about Goldfish.

Anyway its really easy to Format a Data Card on a Fanuc Control. You just hold in these two babies while switching it on.

Oh and make sure you have data card selected in your parameters.

This is me doing it. Yes that’s my gnarled up old hand.

Overtravel Axis Fanuc Parameter 1300

Messing With Parameters Can Be Fatal!!!!!

Over-travel alarm, make this a thing of the past with this parameter

You first need to go to the setting screen in MDI.and put a 1 in the parameter write box.

Today we are going to change the parameter that stops the machine generating an alarm when it gets to the end of travel.

End Of Travel Alarm  Fanuc Parameter

Now I need to start by apologising to all the lovely people at Fanuc. All the years I have moaned and moaned about the fact that when you get to the end of the machine stroke on a Fanuc control you get a stupid alarm.

Actually I have been totally wrong and I offer my sincere apologies to all who have been hurt by my nasty comments about this.

If you set parameter 1300 BIT 1 (NAL) to a 1 then you do not get an alarm when you travel to the end of the machine stroke.

Fanuc Parameter 1300

This should make it work. If it doesn’t then maybe you should call the Samaritans.

Bits n Bobs

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

Other Parameters You may Want to Change

3203 Clear MDI Screen

3202 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit

3402 G Codes that are Active When The machine is Turned On

6005 Allows the Use of Local Subroutines (Newer Control)

6050-6059  Allows you to Call a 9000 series Program with a G Code

6080-6089 Allows you to Call a 9000 series Program with An M Code

5003 Retain Geometry when you Press Reset

3291 Wear Offset requires Key to Adjust

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

That’s it away you go.

This guy has more CNC Manuals than you can shake a stick at.

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.

Or take a screen shot.

Thanks

Cutting Feed-Rate 0% No Movement

When you set you feed-rate override to 0% the machine will not move. Some operators like to use this when proving out a program

All you need to do is make Bit 4 of parameter 1401 into a 1 and the machine will not move even in rapid.

Haas G150 Pocket Milling: How to Use It Like a Pro

I must admit I used to think this feature was a waste of time. But I didn’t realise that some folks don’t have a CAM sytem so long hand programming would take ages.

I got to work on a 1995 very old but brings back great memories for an old bastard like me.

Dirty old beast but then so am I and I still have my uses.

The Haas G150 pocket milling command is a versatile and powerful feature for CNC machinists looking to machine pocket shapes. By defining a pocket’s geometry in a subprogram and then using G150 to call it, you can streamline your code.


What is Haas G150 Pocket Milling?

The G150 G-code command on Haas CNC mills is designed for general-purpose pocket milling. It allows machinists to mill out complex pocket shapes by defining the geometry once in a subprogram, then calling it using a single line of code in the main program.


G150 Explained

The G150 command uses a range of parameters to control the milling operation:

  • P – Subprogram number that defines the pocket shape, can be internal or external (but not on my old machine)
  • X, Y – Starting location (usually the pre-drilled entry hole)
  • Z – Final pocket depth
  • I or J – Step-over distance in X or Y direction, make sure you only include one as you will get an alarm
  • K – Finish allowance for a final pass
  • Q – Incremental Z depth per pass
  • R – Height for pocket, depth is from here
  • F – Feed rate
  • D – Tool diameter offset register (for G41/G42)
  • L – Optional repeat count with incremental positioning

Writing the Pocket Geometry Subprogram

The subprogram specified by the P code outlines the pocket’s perimeter. Important rules:

  • Must be a closed loop (start and end at the same point)
  • Max 40 moves (linear or circular)
  • Start move should go from entry hole to the boundary
  • Final move must not go back to the entry hole
  • Use cutter comp G41 with lead-in/lead-out moves add to cycle.

This example it really simple try it out first just to make sure all is ok. You can then hit it with a much more complex shape.

On older controls you have to put the shape in an external sub program like O500 you can’t use internal sub routine.
