This is EXACTLY what I have been looking for. I toasted 3 1/4" bits by going too slow thinking I was helping the bit out.

The best explanation on chip load I've encountered to date.

Mate, I ripped straight in after watching this video and it felt like my machine has transformed. Thanks from Australia!

Down to earth and still gets the nuance/importance of everything across. I built my own hobbyist machine, and this plus your other videos have been so helpful on determining limits in how to run it and consider upgrades. So glad I found your channel, thanks!

@@cutting-it-close Hi! Could I ask you, do you utilize the chipload .004-0.06" with, designated in the chipload chart, for a 1/8 bit to cut plywood or other wood material? It's look for me too aggressive, because referensing to this chipload chart I have broken two 1/8 bits (one straigh and another spiral upcut one, both with two flutes) using .003" chip load which even less then the lowest border of the chipload range (the cutting paramets I have used for this where 16000 rpm, chipload = .003" and respectivly Cutting feed rate = 96", DOC=0.125").

This was great. I have ask many of CNC operaters about feed and speed. This has answered many of my questions. Thanks for the information. Keep the videos coming.

Man this is exactly what I have been looking for!!! Power is truth and knowledge!!! You saved the day!!!! Thank you!!! Chris

I already feel more confident to try different settings after this. That chart is super super handy thank you for the time put for this video it really stands out from anything else out there on YT.

Awesome video. This actually made a lot of sense to me. I'm looking into my first CNC so I have taken a screen shot of your chart and will definitely take it into account.

I have spent a lot of time today watching videos to help me understand this only to still be confused. Thanks for making it simple to get. I wish I just started and ended with your video!

Just watched four of your videos. Best down to earth, nuts and bolts information in an easy to understand format. Great job.

Exactly what I have been looking for, simple explanation based in the reality of working with wood on a small CNC! Thanks for sharing the spreadsheet too.

I couldn't thank you more for this video. I own a shapeoko 3 XXL with an 800W water-cooled spindle and since I follow your advices on wood/mdf I "see the light" and understand how to work properly. Seriously KZread is full of incorrect advice on machining, you and others convinced me that so-called "aggressive" feed-rates are not agressive, but actually the correct way to go for the tool and the material. You've changed my perspective, thanks!

Thanks for a great video. Finailly understand Chip Load, Feed Rate etc. I have an X-Carve 750 that I bought in 2016 and havn't used for awhile. I did download your spreadsheet and modified it for my situation. I never use bits over 1/4" and go as small as 1/32". I did a calibration test carve yesterday and finally have it dialed in. Definatly making chips not dust now. PS I fided the spelling error in the spreadsheet too. Thanks again and I am now a subscriber

Nice work!! A few years ago I rebuilt an old 1962 Shopsmith lathe. When I turned it on at the lowest speed I thought it was going crazy fast. I chucked a 8" diameter small log into it and when it spun up all the bark flew straight off. I just stood back and watched it for a few minutes. Over time I gained confidence in the ability of the machine to take the vibration and ended up running it faster and faster. I just built a CNC and playing with the different ways to create and feed it g-code. Like any other hobby the internet is mostly full of bullshit sales pitches or Pinterest, Etsy garbage. I know exactly what I am going to do. I made screen shots of the information you presented. I will make a spreadsheet that works and put it on google drive. In fact all of the information I am gathering is going there once I parse it all out and sort through the good vs bad. It makes sense to run a machine slow at first. You want to be sure it is mechanically sound. After that.... I want to know how fast I can push it. Why waste time if you don't have to!! Thanks for making the video!!

I definitely left this video with more knowledge than when I started. Thank you very much, I think you have just helped me save a small fortune in broken bits and damaged materials 👍

This is what I've been trying to find. Found a bunch of internet gurus on forums being dicks and all they had to say is what you just did. Thanks for being helpful.

Welcome!

Wow... seriously i read a lot on that.. And you make it very clear ! Congrats !!

Terrific explanation - this is helpful and exposed a fundamental flaw in my thinking. I have a Laguna IQ because several people recognized this as a strong entry level CNC and claimed it could do everything the larger footprint CNCs could do, just couldn't handle large sheets of plywood. After two of your videos in the last two days, the one on different types of CNCs I realize I have been sadly mistaken. Key lessons I learned from your videos: 1. I mostly use 1/4 inch bits, but when I had an option I would buy 1/2 inch bits because I read somewhere these were better to use in routers and CNCs (opps) 2. When my Laguna would make lot's of noise while cutting, I was slowing down the feedrate. whenever i was concerned about overheating the bit (1/4 ' mostly) i would slow down the feedrate - not increase it. Need to rethink my approach - I wonder how much damage I am doing to the Amana Bits i have been buying. Thanks still catching up with your information - very helpful. Double thumbs up from me. i realize how long this video production takes - I sure hope it starts paying back for you. With your other business this has got to be tough to manage.

Best ever beginner intro to feeds and speeds - PLEASE give us a metric version of this. Many thanks.

Nice. Thanks for that! Looking forward to more videos in the future!👍😁 Oh, and don't forget single flute bits for the small routers that can't move fast enough for the feed speeds required for a twin flute!

Quite an informational video! Thanks to this i was able to do my very first PVC cut perfectly

OMG, this is the best explain in whole youtube, so simply explain so sophisticated and suptile thing in CNC machining. Thank you very much.

i just got my cnc yesterday. this was opposite of what I thought I was supposed to do. Thanks so much. luckily I haven't cut anything yet.

Nice simple explanation with real world production examples. Awesome!

Finally found a video that explains this confusing part of it all. Thanks my friend!

Terrific, thanks for the education. Couple of follow-up questions. Thanks again for you concise, hi-energy, and efficient effort...much appreciated.

Thank you so much I'm new to CNC and this explains why it smells like burning wood in my shop :) I was doing everything opposite to what I'm supposed to be running at for my machine.

I have a laguna IQ and this video is just what i needed to set my speeds and feeds. I like the part about reading the chip that is super helpful. A video about how to hold down the wood and various fixturing would be a video i would like to see. Thanks your channel is always helpful and you are a great teacher

Thanks for the, easy to follow, explanation. This has explained a lot as to why I’m using up 1/4” bits on my hobby CNC machine.

I have a great video coming out tomorrow explaining this more, you’re going to love it!

It's been a while but this video is still very useful today. congratulations, my cnc is small 1000mm x 800mm with 315oz motors 1605 spindle, I did a test flattening the sacrifice table at 6000mm/min really when the machine can cut within those parameters mentioned by you, it's another level although 6000mm/min was the maximum I could at the moment. here in Brazil homemade machines make a lot of dust 🤭 today I managed to make some grains, and it gets a lot less dirty.

Thanks, very useful. I am new to CNC, and your guide is what I need.

Thanks for the video. This is the info I have been looking for!

By far the best explanation of chip load that I have heard! Well done

Excellent display of chip load....well done sir and thank you for the explanation.

Great video! Thanks for taking the time to explain it in the manner that you did.

Thank you so much, Just what ive been looking for.

Wow that was an amazing video!!!!!!!! I wish I could sit down with you and just talk about this topic. I work for a company as an router operator. I consistently get into discussions about this with upper management. They insist on using 3 flute cutters so we can run faster. Only issue with this is the feed rate for that cutter far exceeds machine capability. Not unless I am figuring things out wrong.

Cuttin' It Close my feed rate max is 1,000 ipm. The maximum feed rate the machine can reach when cutting my parts is 500 ipm due to the short distance it needs to move. I just can’t see spending the money on a 3 flute compression bit when that is overkill for what we are doing. A 2 flute compression bit will be good for the parameters my machine can achieve. Thanks for the insight.

Amazing, saw on many other videos and sources to slow down the cutting for a better finish. Didn't think to go faster! Guess its kind of like flying, better to be moving fast or you stall out!

Awesome buddy, many thanks for all the explanation and the excel! Cheers

I learn a lot from you man:) Thanks you!

Thank you so much!

Thank you for this information, so freaking cool!

Thank you for the video. May I suggest in your excel sheet to colour code your answers based on ranges of input. If the 1/8 bit is used, hardwood is used, enter feed rate, rpm, number of flutes. If the answer is below the range, show the number and colour the box into pink. If within range, it is green. If above the range it becomes red. This way you can see if parameters are checking out or not. In the current setup, the answer requires referencing, that can create an error.

Your the man. Thanks!

Been watching your videos and they have helped more than you would imagine. Really like the chip load chart you provided. Do you know if there is one for smaller bits or do you use the same chip load for 1/8? I would think that would be too much for a 1mm or even 1.5mm. If you could help. Thanks.

Thanks for a great video, much appreciated!

great video. thank you

Great video, thanks for sharing. Being unfamiliar with excel just need to work out how to add formulas to get the required chip loads, speeds and feeds.

Thanks. That really helped. I have a Onefinity so 1/4 inch is my biggest except for the one inch surfacing bit. Some speeds seem fast but good to hear it from a pro. 😊

Great job thank you

The hand and sawdust presentation is a perfect way to explain proper cutting. Haha

Amen. I understand now that playing with the rpm and feed rates as variables you arrive at the recommended average chip load... took a min and serveral beers, but thank you :)

Same here!

This is a great video. Very helpful and informative. I recently bought a 30"x30" Longmill MK2. I noticed you set your depth per pass at 1x-2x the diameter of the bit. But I recently saw on Xcarve's recommendations that you should only set your depth per pass at 1/2x the diameter of the bit. Do you think this is just a way to try and keep the rates conservative? And would that potentially heat up the bit more like you said and actually make things worse later on? Thanks again for making this content.

Great video,, thanks for making this. !

Good info. I have a large 48 by 96 CNC but who ever built it thought it was a good idea to but a 400 watt Spindle in it. I run 1/8" bit at little over 1/4" and speed of 72 which seems to work well. My stepper are a little small and are direct drive, not sure i could even get 100 IPM. I will have to do some tests to see what it is capable today.

Thank you, very useful for a beginner

Hey ... excellent video ... but a question ... specifically for cutting with a hobbyist level cnc, into hardwood, with a Vcarve bit (2 flutes, 1/4" shaft) ... you mention to use an 80 IPM feed rate, BUT ... what RPM would I set my spindle to? Does it matter if the bit is 60 vs 90 degrees? Do Vcarve bits have a 'diameter' (that could then be used to calculate chip load)? Thanks! Gary

This is a great explanation of chip load but working with partial board laminated with Formica ads another equation to situation. We run coated 2 flute compression bits on a Felder H10 CNC at 18.5 meters a minute at 18,000 rpm and might get 25-30 sheets cut sometimes less on a bit. Plain old melamine on a coated bit will last 60+ sheets. If you have any suggestions that would help for longer bit life I'm open ears.

Hey this is Saharsh from India. Your videos have really helped me figure out CNC machines and the basics of starting a woodworking company here, specially since this kind of information is not as easily available and you cant always trust machine suppliers. P.S Anyway and I can reach out to you for queries? If it's not too much of an ask?

Could you clarify the V-bits feed rate. Your chart has simply two V-bit feed rates based on number of flutes. How is this used to calculate considering tool diameter and material? Thanks. Love your straight forward explanations.
