G80 G-code Fanuc

Category : Fanuc Fanuc Mill News

I noticed a common search in google is G80 G-code Fanuc.

CNC Machines use what we call canned cycles in a nutshell G80 cancels a canned cycle.

What is a canned Cycle?

To be honest I think it is a funny choice of words “Canned Cycle”.

My guess would be that all the information to drill a hole would be kept together in a “Tin Can” to use whenever you want.

I made this…….G80 G-code Fanuc

First of all we program the cycle this is a G81:

G81 G98 Z-10. R1.5 F200. X55. Y55. F250.

The machine will move to the position X55. Y55. then it will rapid to 1.5mm above the part (this is the R1.5). It will then feed down to Z-10. at a feed-rate of 250 mm per minute F250.

Finally it will use rapid to come out of the hole.

It then sits ready for the next move.

 

All you do now is just give more positions.

G81 G98 Z-10. R1.5 F150. X56. Y56. F200.
X70.
X85.
X90.
X95. Y65.
G80

Every time it moves to a position it will do whatever you stated in the canned cycle (G81)

You don’t add anything else to these positions.

G80 G-code Fanuc

At the end use the G80 (G80 G-code Fanuc) . It means “No more holes please”

From that point onwards if you program a position the machine will just move to that position and do nothing.

G80 G-code Fanuc There is More

There are lots of these canned cycle here are a few examples:

G84 tapped holes, tell it the pitch depth usual stuff.

G84 G98  Z-10. R1. F1.75 (Tap me hole 10mm deep at a 1.75mm pitch)

 

G73 we call this peck drilling, just like a drilling cycle (G81) but it will peck the hole into small cuts.

G73 G98 Z-25. R1. Q5000 F250 the Q5000 means it will make each peck 5mm

G83 same G73 but with each peck the drill comes right out of the hole. For deep holes where the swarf clogs.

Wondering what the G98 is for?

Check this out G98 G99

All it is in a nutshell. G98 returns to the Z point you were at before you started the canned cycle.

G99 will return to the R point (R1.)

CNC Machine Training Classes now running at the CNC Training Centre

Beginners

Setter Operator Beginners Turning

Setter Operator Beginners Milling

These two courses are designed for beginners who want to learn how to set and operate a CNC machine and are for students with very little engineering experience.

 Learn to Programme

Learn To Programme Turning

Learn To Programme Milling

If you already work on a CNC Machine but you want to learn to programme then the two courses above are for you.

Absolute Beginners

I have added these courses which are for students with very little engineering experience. They cover the basics of milling and turning in preparation for learning to programme.

Beginners turning

Beginners Milling

 

They are two day courses but pack a lot in, covering tooling and measuring instruments. I am drawing from my vast experience in industry, on the coal face as it were, and knowing the very basics skills that are needed by a CNC operator before he begins to learn about programming.

The New CNC Training Classes and Courses focus very much on the basics giving a solid understanding of the nuts and bolts of CNC programming on an ISO Fanuc Haas type control.

The Story

I am going to ramble on, because I always do, but it made me think of when I worked with my dad many years ago. My dad was a brilliant old school engineer and he worked for Alfred Herberts from boy to man, apart from a brief period in the RAF.

New CNC Training ClassesHe got made redundant and had his pension robbed when AH finally went bust. I was running an engineering company so it seemed obvious to have him working for me.

I learnt so much from my dad about the basic principles of machining (this is the link to the training courses) albeit tenuous. His claim to fame was that he worked the first Cri Dan machine. This was an amazing innovative machine that could hold it’s own, until fairly recently, against a CNC lathe for high-speed threading. There are still a few about now.

New CNC Training ClassesMy dad often joked that he could offhand grind a 1/16 of an inch drill and read a steel rule to a thousandth of an inch which I am sure was bullshit although I would never dare to say. I remember we were trying to turn and bore some motor bodies on a Mori Seiki lathe and we could not get them round. Anyway he told me to weld up some jaws so that they would fully envelop the part.

CNC Machine Training ClassesCNC Machine Training Classes

Basically it had nowhere to go it was like a big collet and it worked. But there was another lesson to learn. Our inexperienced inspector was trying to measure roundness with a micrometer which I am sure you all know cannot be done.

CNC Machine Training Classes

 

An argument ensued and profanities were exchanged. We ended up buying a Talyrond roundness checker which is the correct tool for the job.

New CNC Training Classes

 

As it happens the same thing cropped up in a customer’s only a few months back. I caught them trying to measure roundness with a micrometer. Back to basics again.

These days I have a much better way to prove my point than shouting and swearing and it’s cheap 50 pence to be precise.

 

I threw them a 50p piece (UK Currency) or even a 20p for the real cheapskates. “Is that round” was my question. They laughed

.

“Here is a micrometer now check it for roundness”.

Mmm it’s dead round when you check it with a micrometer.

The smart arses amongst you will know that a 50p piece is an “equilateral curve heptagon“. And it measures the same across any two points you care to choose. It proves that you can’t measure roundness with a micrometer.

I won’t be teaching you about roundness on these courses ,that would be silly you already know, but if you are interested in learning basic CNC Programming for a Lathe or Milling Machine look no further.

The New CNC Training Classes focus very much on the basics giving a solid understanding of the nuts and bolts of CNC programming on an ISO Fanuc Haas type control.

Make sure you have the Macro option on your control, it’s a real disappointment when you get all excited about this only to find you don’t have the option. Remember if you have a touch probe you will almost definitely have Macro installed on your machine.

Good news is you can buy the option, it don’t come cheap so sit the boss down and make him a cup of tea before you ask.

What Use Will it Be?

This is where CNC Programming gets really exciting, welcome to the turbo charged world of Macro Programming for Haas and Fanuc type controls. There is so much exciting shit you can do with this I really don’t know where to start.

Write your own canned cycle

Yes you always dreamed of having your own personal G code, you can’t call it like Bill’s G code or something but you may have G271 or something which is personal to you.

Say you wanted a drilling cycle that changed speed half way down a hole or some daft thing well now you can do it.

Make A Set of Similar Parts

Imagine you had a bunch of parts that were similar, maybe the same holes but in different positions or a similar shape.

Haas Macro Programming

You could write a parametric (Macro) programme that would be completely adjustable and would make them all instead of having to keep writing similar programmes.

You can build these programmes and add to them as you get better and better and your ideas flood in.

I always say to students to start simple and build on your experience. Just using Macro in its simplest form will inspire you to go on to do greater things.

Interrogate Your CNC Machine

You can get almost any information you want from the machine.

  • Spindle Speed.
  • Position.
  • Datum.
  • Tool Length.
  • What tool is in the spindle.
  • Put the machine into an alarm state when things go wrong like wrong data is input.
  • And loads more.

You can even modify this information and send it back.

Do Calculations

  • Simple trigonometry.
  • Calculate feeds and speeds.
  • Simple maths.
  • Input formula and get answers.

I’m getting really excited just telling you this. It means you can add all sorts of functionality to your machine that you didn’t have before.


What Skills Will I Learn

  • Basic use of variables
  • Creating simple Macro programmes
  • How system variables work
  • How to write probing Macros
  • Creating your own G Codes
  • Create alarms to make sure your Macro users behave
  • Practical use of Macro
  • Creative use of Macro
  • and more, loads more


Canned Cycles Using G98 G99

This article is about CNC Canned Cycles Using G98 G99

Canned Cycles Using G98 G99

(G Code CNC Programming)

It’s not a competition G99 vs G98. sometimes you need G98 sometimes you need G99.

CNC Canned Cycles Using G98 G99, a canned cycle is usually one line of code for example to drill a hole. This one line of code tells the machine all it needs to know about drilling my holes.

G98 G99

  •  Depth
  •  Feedrate.
  •  Point to rapid to before drilling
  •  Point to rapid back to after drilling

Canned Cycles Using G98 G99

G Code Programming Haas Fanuc (ISO) Mazak

What happens then is each time we give the machine a new position it will drill one of these holes. Each hole will be identical unless we change one of the parameters. So if on one hole we put a different Z depth that hole and all subsequent holes will be to the new depth.

CNC Canned Cycles Using G98 G99

So all in all it’s a really easy way to drill holes. You tell it what you want and then each time you give a position you get a hole. Then when you get sick of drilling holes you type in G80.

Machine says OK he don’t want anymore holes so from now on when the machine moves to a position nothing happens.

Mitsubishi Carbide

There are loads of Canned Cycles I can’t be bothered to tell you about them all cos I’m going out tonight otherwise I would explain them. Anyway they all do different stuff like.

  • G84 Tapping
  • G73 High speed Peck Drilling
  • G83 Deep hole Drilling
  • G81 Drilling

They all work in the same way as each other but with variations.

Now the video at the bottom of the page is about CNC Canned Cycles Using G98 G99 and that’s in all the drilling and tapping type cycles.

Ok what does it do? You may well ask, G99 vs G98

I know for a fact that some of you, and I won’t mention names, put this on the line with the canned cycle but you ain’t got a clue what it does. Maybe you don’t even put it in. Maybe you don’t care.
Anyway it’s simple.

  1. You rapid to an initial point
  2. You rapid down close to the hole (this is the R point)
  3. You feed down to depth (Z Depth)
  4. Then you rapid out to either the initial point (1) or the R point (2)

Canned Cycles Using G98 G99

Now if you program G99 it returns to the R point .
If you program G98 it returns to the initial point (that means the first one)

Ok why on earth would I want that?

Well……. if you made the first point say 50mm above the job (About 2 inches) and the rapid point was 1mm above the job (.040”).
You could drill all your holes in G99 and the drill would each time return to 1mm (.040″) above the part. You get to a clamp and you put G98 and it jumps to 50mm (2”) above the part and misses the clamp. Change back to G99 and it stays down returning to 1mm (0.040) above the part.

Get it? So you eliminate wasted moves. Good init.
