CNC Work Offsets G54 to G59 How to Use Them

As part of the basics of CNC Programming you need to have a good grasp of Work Offsets. This article explains how they work on various controls. Bridgeport using Heidenhain to Matsuura using Matsuura G-Tech 31i control.

Haas below.

Make sure you read to the end to see how good use of Work Offsets can dramatically increase production on your CNC Machine.

G02 G03 Circular Interpolation

On a Fanuc or Haas control G02 G03 are the two G codes we use to move around clockwise and counterclockwise circles. You don’t need the leading zeros so from now on I will call them G2 and G3.

If you want to know how to do this on your Heidenhain control you need to read this article.

Oh and please don’t call it interpolation as it annoys me.

Linear interpolation is…

G Code Programming Made Easy

When I first started training people at The CNC Training Centre many many years ago in the fine art of G Code Programming. I soon noticed that people were getting really confused with all the different G Codes.

The first basic thing you need to know is the concept of X Y Z.

I’ll talk about this in another post.

Anyway………

After a day’s training.

Students would make comments like “I have all these…

Learn CNC Canned Cycles G81 G84 G73

Learn CNC Programming (Canned Cycles) A Canned Cycle What is It?

If you want to learn CNC programming then you need to know what a canned cycle is.

I’m going to have to be honest here it is a funny choice of words “Canned Cycle”. But a wild guess would be that all the information to drill a hole would be kept together in a “Can” ready to use.

In a Can…….

So let’s learn CNC Programming….

G76 Threading Cycle How Many Passes

G76 Threading Cycle you must agree that it’s not easy to use.

Read this article, no more sleepless nights worrying about G76 Threading Cycle. Myth busting information that simplifies and demystified. Applies to Haas, Fanuc and Mazak ISO

Be sure to read the end of this article to see a simple way to calculate the number of passes needed.

I noticed quite a few people posting problems on Machining…

Rigid Tapping G84 Canned Cycle

Rigid Tapping G84 Canned Cycle, let’s face it tapping on a CNC Machine can be a “right pain in the arse” as we say in the North of England. But help is at hand. All you need is a bit of knowledge and the right equipment and it’s a dream, an absolute pleasure.

What is Rigid Tapping?

You mean you didn’t know? Well the first step is admitting you didn’t know.

Rigid tapping means the tap can remain…

Avoid CNC Crashes Don't Reinvent the Wheel

Avoid CNC Crashes Don’t Reinvent the Wheel

This is an article designed to help you avoid CNC crashes.

I listened to a fantastic documentary on Radio 4 the other day about Airline Crashes. The programme explained how the hierarchy (cabin crew, flight crew) caused wrong decisions to be made.

In the Kegworth air Crash,cabin crew knew that the pilot had shut down the wrong engine. Unbelievably no one felt empowered to tell the pilot. The…

CNC Programming Safely Using Decimal Point

CNC Programming Safely (Decimal Points) CNC Programming Safely is very important so this post explains about the decimal point. Decimal points who needs em eh. On Fanuc controls and Haas controls depending on how you set a parameter number input can be taken in two ways. X20 is taken as a movement in X of 20mm this is like a calculator and some controls will convert this to 20.000 for you. Or X20…

Haas Spindle Warm Up Macro

Warm up Programme

This Haas Spindle Warm Up Macro is something I created recently for the Macro training course that we offer at the CNC Training Centre. The course covers Macro Programming suitable for Mazak, Haas and Fanuc.

I must admit I often think that where Macro programming is concerned, a little knowledge is a dangerous thing. I just think it’s more about a programmer’s ego than really…

Checking CNC Programmes

Checking CNC Programmes (Prove-Out) Without Tears

I am always amazed when I watch people Checking CNC Programmes or proving out as it is sometimes known. Even experienced machinists with years of experience often do this completely wrong. It really can be done without crashing the machine.

What You MUST NOT DO When Checking CNC Programmes

Don’t allow anyone to stand over you especially if it…

CNC Crashes ** Think The Unthinkable

Every CNC Setter, every CNC Operator, every CNC Programmer they all have a story about their worst CNC Crashes. I’ll tell you about mine in a minute. That’s not what this post is all about. Today I want to give you something to think about next time the unthinkable happens.

It all happened on a machine not unlike the one above, good old Mori Seikiwork horse.…

CNC Lathe Tool Nose Radius Compensation

This video “CNC Lathe Tool Nose Radius Compensation” is a follow up from my previous video “Tool Nose Radius Compensation on a CNC lathe”.

When you use tool nose radius compensation on a CNC Lathe (that means we are using G41 and G42) you have to tell the machine where the cutting point of the turning tool is so that the correct tool path is produced.
