Welcome to my videos on hopefully being able to teach beginners who have never programmed a CNC machine. I myself programmed HAAS CNC Lathes for over 15 years and I started from scratch not knowing anything about writing codes!! (Aggghhh!!) I had to manually write new programs at the machine controller and that’s kind of what these videos are about. Most places now probably have a dedicated person for writing programs and drawing blueprints…but, If you are just starting out and need to learn how to program by hand, I hope these videos will help 🙂
In this video, I explain how to program a G71 canned cycle. A G71 is a stock removal canned cycle that I used all the time in programming. I know this video is kind of long, but I wanted to make sure I explained it clearly 🙂 Hopefully it will make sense after you watch me ramble on….ha!!
I realize this may be a more advanced video for beginners….but, I still figured it could help out.
Please be sure to check out my playlist of my other CNC videos!!

Thank you
I’ve been trying to run a g71 cycle on a haas st10 but I keep getting an alarm that says (370 canned cycle geometry error) and I went through the user’s manual and still couldn’t figure out why I’m getting this message
If you are using a different tool for the finish pass do you rapid the tool into the starting position and then apply the the g70 code?
Why would you not go into a g70 cycle to have a nice clean up pass?
Amazing, thanks for the awesome video!
First off, THANK YOU for taking the time to explaine all this! You make it so simple for someone starting off without any experience in tool and die!
I have been working more and more with our CNC machines, but I am burning through carbide inserts on my boring bar. The culprit is a backside chamfer on an ID (or so I think). The program has the boring bar plunge into the DOM after it finishes removing the inside material, and it causes the tips to break often. Do you have any suggestions on what could help extend the life of my tips?
will the canned cycle also repeat m code if its in the code like for opening and closing a steadyrest or clamp type follow rest on a shaft?
