CNC Programming G43 G44 G49 CNC Milling Lesson 8

In this lesson I will explain how to use the code for setting and cancelling the the Tool Length in your program. Try and memorize these codes while you wait for the next video.
Whether you are a manual machinist, a hobbyist or just interested in learning how CNC programming code is structured, then this video series is for you. This series will teach you all about programming language so that you can manufacture parts without the aid of CAM software.
Upcoming videos will cover dozens of codes and their proper usage including troubleshooting common code problems.
Learning how to program with CNC code will open up many opportunities for you in machining and manufacturing.
Please feel free to message me if you have any questions or would like any further help in CNC machining. I am a machinist by trade and worked as a CNC machinist for a decade before beginning my teaching career in machining and CNC programming.

I use the g49 function like parmesan on pasta but I can't understand the usefulness of recalling the g43 function.. If I insert the T1 tool into the spindle which I hear defines g43 h1. It seems obvious to me to attribute its length to that tool. I'm not stupid enough to call T1 and give it the value h2. I hope I didn't guess the use of the g49 because it's really stupid. I consider g49 useful instead because it is useful for obtaining dimensional tolerances.

@stefanodeberardinis Thank you for your thoughts. G49 is mostly useful in the safety line. This is just in case a machine was shut down or the power went out while a tool was not homed after use. G49 just cancels the last tool length that was compensated for. Remember that if you use G43, it stays active until you use G49. So if use use G49 "like parmesan" then you will have to call up G43 for the next tool you call up. Only G43, G44 or G49 is active at any time.
Thanks again for reaching out.

Hi Adam have you had time to put the speeds and feeds up for the bridge port mill

[@adamtaylor999]

Good day Santo, sorry I haven't posted yet. I have been working on a new video series and this ended up taking a back seat. I will record a feed and speed video this week and post it. Thanks for the reminder. If you have subscribed to my channel and turned on notifications then you will see when the video goes up. Have a great day making chips!

Adam thank you buddy I can’t wait to get out in my shop and try it. Again thanks

Yes I put up the Mill Feed and Speed video and messaged you a month ago. I think you may have watched it already.
