CNC Turning G Code List For Beginners
Download and print this nice large print CNC Turning G Code List
I always begin my training sessions by telling my students not to remember anything I say.
This sounds completely stupid and my excuse is it wasn’t my idea to say it.
About ten years ago I worked in France. After about a year and it seemed obvious that I would need to speak to people to order “Fish n Chips” and stuff like that.
Anyway I got these CD’s to teach me French and the bloke (can’t remember his name) started off by telling you not to remember anything he told you.
I think there is a bit of reverse psychology going on but the main idea is that you understand not remember. It didn’t work for me because I still managed to completely fuck up the language. Not realizing French Canadians speak differently to native Frenchmen (I was working for Bombardier) . Anyway I asked this bloke, in French, to “come with me”. I can’t remember what it is in French and after all the bloke on the CD had specifically told me not to remember.
Anyway turns out this had a sexual connotation and made me the complete laughing stock everywhere I went from then on. (I’ll let you do the maths on that one.)
Now I know what your thinking, “that is the gnats cock of CNC Turning G Code Lists”. Honestly size isn’t everything.
Learn these first and just by seeing um every day they will just sink into your brain.
When it comes to CNC Programming it is important to enjoy your self and not get bogged down trying to remember loads of G Codes.
The truth is you only need to remember a few and it’s all about understanding what they do.
For Example This is in your Program.
You watch in amazement as it cuts your part.
So you look up what G71 means on your list of G Codes printed in large letters on the side of your machine.
“Oh yea it’s that’s roughing shit” you say.
As You Watch it Run It All Makes Sense
You understand how the cycle works already.
So as it runs, it all makes sense.
Type up or print this list in nice big letters and stick it to the side of your machine
