Intro to CNC: Axes and Offsets

In this video, I talk about coordinate systems, types of CNC machines, tool offsets, and how to understand the axes on a CNC machine.

Excelent video!! Very acessible. Thank you! Was exactly what i was looking for .

[@dfkirby87]

Great video man!! A very clear explanation of the root elements of CNC machining.

[@huynguyen-gn3nc]

Thanks Robert Cowan the way you teach very easy understand by making X , Y , Z on the block . i love It 👍🎁

[@HunterNugent1]

You should be rewarded a golden KZbin reward. I want to watch more...you rock!! I'm a 46 year old sr. mech designer that wants to do some side work and I can't wait to get my 440! Thanks man!

[@genek1341]

excellent video , very easy to understand the way you described axes and offsets .

[@MaxEkman]

Very nice videos on starting out with a Tormach, and CNC in general. I like your format, clear and right to the point. Keep up the good work!

[@RobertCowanDIY]

Thank you! These videos are much harder to put together because of the planning and organization, it's nice when it comes together!

[@MaxEkman]

+Robert Cowan (Rowen Hobbies) I can appreciate that, but totally worth it IMO. Thanks again!

[@orlandosanchez520]

Thank you so much for this video I'm just starting with milling and dint have a clue as to what the process was to start cutting in the right spot according to the software. man you make it so clear. after watching this it's like a lightbulb went off. i just cut my first part thanks to you.

[@EZ_shop]

Very well produced and informative Rob.

[@michaelthompson525]

Ive got a tormach 770m and have had it for 7-8 months now and ive used the conversational part of pathpilot. I have milled a couple of simple things but fusion, wcs, offsets its such vast thing to learn let alone master. Ive been having trouble with work offsets especially and making fusion and my machine communicate but your video explained it better than tormach, ny cnc and many others. You should continue with these i will be watching them to hopefully master machining.

[@vrva3138]

You are the best. The x y axis movement made me scratch my head for a few days until i watched this. thank you!

[@dannyk847]

Same here. He could not have made it easier....

[@mamdouhnoshy9620]

Thank you kindly for your great efforts, and for your time

[@bluehandsvideo]

Great video Robert! Very clear. Looking forward to more along this line. :) Mike

[@internationalprecisionengi1737]

The table moves opposite, because its "aligning the tool tip to the desired coordinate on the part". The coordinate system is relative to where the machine thinks is the part, and the coordinate solution (the number you see on the screen), is the relation of where it thinks the tool tip is relative to that part. Im sure its been said, just wanted to bump it to the top. The production on these videos is a perfect balance of quality vs quantity, keep it up!

[@cllamasful]

Can i just say I've been watching the videos so far up to this point. I have a very very vague idea of CNC machining. But your videos are extremely simple, yet informative. Excellent work! Thank you!

[@RobertCowanDIY]

Thanks so much!

[@cllamasful]

Would you recommend the 15L slant lathe for spinning molds?

[@RobertCowanDIY]

I don't have any personal experience with it, but most people that have the 15L absolutely love it. I'd like to have one in my shop someday. Sorry I can't be of more help, I just haven't ever used it.

[@RIGHTEOUSMARKETING]

Bro you are awesome! You explained it very well.

[@MrMarcosviloria]

Hermano Robert lo felicito por tan exp`licito conciso y veraz video muy claro, excelente trabajo, saludos a su persona.

[@RobertCowanDIY]

gracias!

[@fufatem6733]

what a great presentation

[@1bulldog998]

VERY NICE DEMO THANK YOU FOR YOUR TIME

[@halgburi]

In 20 minutes you did explain things that I couldn’t understand in days, sometimes the way of telling is really make difference

[@westerngodzilla]

Nice video. Keep up your good work! I like this very much .

[@RobertCowanDIY]

Thanks!

[@VLAHECO]

awesome explanation about cnc One day I will have my own Tormach

[@markdion9932]

great job. wish everyone kept it that simple

[@fredfarnackle5455]

Thanks for the video, I never really understood offsets - now I know.

[@gursimarsingh2358]

very beautifully explained

[@BighomieCdawg]

thanks. you're a good instructor

[@buzga1987]

Excellent video as always. Nice explanations, easy for beginners. What camera do you use for your videos? It looks really good.

[@RobertCowanDIY]

Thanks! I just switched over to a Sony A7RII. So far I really like it.

[@TheFixxxer11]

thanks for the info,, it solve my puzzle .. I get confused between gantry router with bed mill,, about x,y axis position ,, which way is +, which way is -,,

[@aakashdevadiga1785]

Helpful

[@jf.knivesfrederick3657]

very helpful and super well put together, what is your opinion on a G0704 converted cnc as a first machine? While I would love to get a Tormach its a little over budget.

[@RobertCowanDIY]

A converted G0704 or similar is a good first mill. Just keep in mind that if you're 100% new to CNC and machining, it might be a bit overwhelming dealing with the conversion along with learning CNC at the same time. It obviously can be done, but it gets very frustrating. For people just starting out, I'd recommend getting a kit for the mounts and such, just to save yourself a lot of time and hassle.

[@jf.knivesfrederick3657]

what do you mean by mounts and such? This is me being new to cnc lol I was also told by someone in cnc that a 440 would be better.

[@al-hasanwasim6459]

Can you give us a detailed explanation of the G code?? Regards

[@levinrio7685]

Robert. after all this years do you have any regrets owning the 440 or do you wish you just stepped up to a bigger more capable machine if you can turn back time?

[@JonathanRansom]

Are you planning on doing any videos on all your K40 mods?

[@RobertCowanDIY]

I might do a short video outlining everything I did. I did an upgraded exhaust (12V bilge blower), air assist (using an aquarium air pump), honeycomb table, and LED lighting.

[@JonathanRansom]

It looks great. I've been eying the K40 for a while but reading about a lot of people having trouble with them when they come in. Where did you get yours from?

[@RobertCowanDIY]

I've used Epilogs before and this is definitely not an Epilog, but it cuts alright. I got it for very little on craigslist. The new ones on eBay have a lot of the mods that I did already done to them and people have had good luck with them. Just don't buy the cheapest one you can find. I think for the money, they are good, as long as you understand the limitations. I used mine just the other day to cut some acrylic parts for a prototyping jig I was working on. It's MUCH easier than machining the parts and makes rapid prototyping a lot easier.

[@nolver53]

Very helpful video, thank you. Just one question; as you're swapping tools, does the computer have a way of remembering the offsets when you are changing tools? Maybe I missed that part of the video. Your videos are very well made. I am getting ready to enroll in school in January to learn CNC Machining. For a absolute beginner like me who knows nothing about CNC Machining, your videos are very helpful. Again, thank you!

How to align work piece with machine coordinate system?

[@sylvainforget2174]

I am so glad I did not learn anything new. I would hate to learn anything from an intro video after spending over twenty years programming, setting up, and operating cnc turning and machining centres(or cnc lathes and mills if you prefer). This video is done well. Nothing wrong except that I prefer to use a 1 2 3 block for the Z offset, raising the column until the block slides under the tool. I just find that it is a safer way to do it for me.

[@manishchauhan9495]

How do i find center of round workpiece

[@RobertCowanDIY]

Find the center in the x direction, then the center in the y.

Love the continuous learning the machining trade gives us. So glad I chose this career path. I'm in my mid 20s and hope to eventually open my own business doing what I love to do. But for now I'm growing within a great company called Cloeren Incorporated. My hats off to all of you in this trade.💯

[@RobertCowanDIY]

That's good to hear. I am not even remotely in the industry, but it's good to hear people are having positive experiences with it.
