Surface Speed and Finish

[@jimsvideos7201]

We'll be here, Peter; your content is compelling. Take care of the family first.

[@Sicktrickintuner]

Won’t ever loose track of you. You always teach us all more then we could ever have. Let yourself go and do what you need to. We will be here. And very interesting seeing the difference in speeds from slow to fast.can really see the tearing of the base metal instead of shearing.

[@garrettweaver2184]

Peter I would love to see you make a “turning tips and tricks” type video where you go over all different quality of life things you do on every part. For example I always chamfer the raw stock that is left on op1 slugs so there is no burr when the operator is loading it for op 2. I imagine you have lots of different tricks! Great video as always.

[@boulder795]

This would be a great idea. It's certainly something I was looking for and couldn't find when I started turning a year ago. Stuff like turning outwards from the chuck for better chip management on finish passes, reading what the chips are telling you, definitely anything on dealing with chatter on turning long spindly parts.

[@christianedelmann6880]

I am an engineer who designs components for machine tools. Ever since college, your videos have helped me design for manufacturability and really get a better idea of how thinking about parts holistically from concept to manufacturing can make everything more efficient and cost effective! Thank you for being an incredible resource!

[@paulmace7910]

Thanks for taking time to put this together for us. You do what you can when you can. Your fans understand and will be here.

[@Steve_Just_Steve]

Peter really appreciate what you do on this channel. You're tight there little to no content like this. It's all just clips with no info or the same ol' YT machinist showing how to dial in a 4 jaw for the 746th time. So thank you!

[@jimsvideos7201]

Also I propose we call this the Stanton method; simple, elegant, effective.

[@dougcook1176]

Thanks for taking the time to shoot the difference so clearly. The macro photo's were great!

[@levitated-pit]

you are an excellent teacher! ive been in the industry since i was 16 yrs old. im 61 yrs old now . i still learn ..everyday! thank you Peter.

[@tedsaylor6016]

Peter. you are a Pro's Pro. Don't worry we will never mistake you for your new "titanic" neighbors in Dallas. Steady as she goes, Sir.

[@danielwcrompton]

As a layperson with only secondhand machining knowledge I love you in-depth detail oriented videos. All content is much appreciated. I hope all goes well with you family. I know hospice situations can be difficult to deal with and need a lot of attention. 🧡

[@brantonbeall9061]

We will be right here, continuing to follow and looking forward to your superior content. Family first!

[@BruceBoschek]

When your life needs you don't worry about making videos. We will not forget or abandon you or your channel. Your content is unique, as exemplified by this extremely interesting and useful discussion of surface speed. Thanks very much and best wishes to you and your family at this difficult time.

[@joshmonroe2562]

Cool video Peter! Thanks for taking the time to make it for us all to enjoy.

[@stevelush9994]

Peter you are an amazing educator and very humble at the same time I think it unlikely that any of your followers will go away regardless of how much or how little you post. Your priority must always be your own needs and that of your family I treasure every video you have done for us especially your own personal insights keep up your wonderful journey. Regards from Australia

[@warrenjones744]

We won't loose track of you Peter. Gotta deal with what life brings you as it comes. I like what you bring us when you bring it. Your projects are very cool and for the most part pretty unique.

[@cooley2379]

I have to say, I have been following your channel for over a year now and your content is the most educational content I’ve seen. I agree that videos that show high speed machining and such are neat but your content gives an educational take on machining. Keep up the great work and looking forward to more videos!

[@bazookamoose7224]

My condolences, things like that are very difficult and emotionally jarring. Your content is always a great addition to the community! My prayers for your family, and thank you for everything you do!

[@HuskyMachining]

this channel has been like a father to me. please don't change! I learn best by watching and your content gives a lot of knowledge for free

[@tdg911]

Always appreciate your videos. Very informative. Many prayers for your mother in-law and your family. Much love

[@fredflintstone8048]

Just wanted to let you know that youtube always presents your new videos to me within a day or two of you making them. I never miss one of them. I always appreciate your videos and learn something from them even though I don't work in your industry. I'm a hobby shop machinist with a manual mill and a lathe. The take away for me from your videos are solid principals in precision machining which are always of interest to me since I consider myself a perpetual student of the craft. I have a long career of automation programming in various fields. I have training in electrical and mechanical engineering and I apply those. Back in the 90s as a sort of side job I did a lot of G-code type of programming to support a cnc machine shop that built models for IBM systems, as well as software to automate work done in a cnc pcb manufacturing shop at the same IBM facility. I also enjoy that topic very much as an automation engineer, and think that I may some day get into some cnc if my life takes me in that direction. It's all good, and I hope things go well with you in your home situation. I'm always happy to see one of your videos pop up and to let you know that no matter how long between your videos, you have a loyal fan who watches and learns from them.

[@toolbox-gua]

I'm a little late to "class". The least you have to give apologies, your family and your self goes first and second and third. Thank you for your time and effort to share your knowledge.

[@tomazbeg1999]

Great video. This information is exactly what I’ve been looking for. Thanks for sharing!

[@772tsweet77]

Not in the industry but I can appreciate the whys and hows. Really this machining is a fascinating world. I learn little bits that I can apply to my life. Stay curious everyone.

[@owievisie]

Great short video Peter thank you very much

[@kevlar_87]

That's cool, I really appreciate the macro lens shots. Thanks for the video ☺️

[@WilliamPayneNZ]

Best wishes to your family Peter. I looked after my Dad when he was sick with cancer before he passed I know what it is like to juggle that kind of thing and work. Take care.

[@bhavarkumavat3202]

Hmm , so Higher Cutting Speeds == To Better Surface Finish , but more heat , Lower Cutting Speeds == Dull Surface Finish but more stability , and less heat 🌸🌸 thanks ! For showing great video 🌸🌸

[@Chris-kk8xg]

I will always try and watch your videos the second they are uploaded

[@rexmundi8154]

Thanks for the upload. I’m sorry to hear your in-law is sick

[@tomsemo8186]

Excellent. Great visual. I'll pay more attention from now on.

[@brianbures4478]

Great video as always Peter!!!

[@Grazy1967]

this is purely a matter of experience, if you are experienced you will always find the right speed for the respective diameter and the respective material, it just takes time to learn that, that's not so important anymore but I had to/was allowed to learn with HSS and too high a cutting speed was deadly for the chisel, and you just had to grind it down, which is also what you learned ;-p thanks for the video, and sorry for the English, its from google^^

[@gilbertotejeda4167]

What's your finish doc? / Nevermind, saw you answered this in another comment. Also it's amazing how similar I would judge to run the lathe in soft steel :) Did a conversion to metric, and all the numbers are super close, all from roughing+finishing speeds and feeds to finish doc.

He sold his stuff and closed

[@thingstoknow]

Hy, i would like to appriciate the way you make things clear. i want to ask a question if you do and. 1. Steel Roughing SFM, and finish SFM. 2. can we use same feed speed for bigger diameter workpiece and for smaller diameter?

[@cristinelpricop]

If you post hourly I'll watch all day long your channel :)

[@hk-bp5ku]

I love your channel. I have been working on CNC machine for years and still don't understand why the finish is so bad at lower speeds and I have never seen one either. i think the key is the fact we don't cut the material, we push a shear point along the part. What is your opinion?

[@CorndogBrownie]

Family first, above anything else. The videos always turn out great in my opinion anyways. And it's not as of I don't get a video every month, hell even months on end, I would cave in our misti shrivel up and fade away. Always here

[@MrKingdavis13]

Sorry to hear about the issue your family is going through right now.

[@Dr_Petey_Wheatstraw]

Do you have any idea what the mechanism is for this drastic difference in surface finish? Is there a certain heat generation threshold? (eg does this rule change with flood coolant vs dry?). Super fascinating, should help with my hobby work.

[@EdgePrecision]

It still apples with coolant to a lesser degree. I ran it dry for the purpose of the video. I also selected a soft mild steel. Because it is more pronounced in soft steels. If the material has a heat treat it is less sensitive to surface speed and finish. It has to do with how the tool cuts the material. A carbide insert will be different than a HSS tool. Every material and tool combination has a sweet spot.

[@bcbloc02]

Usually the fastest sfm without burning up the tool gives the best finish with the fastest material removal rate. Win win!!!

[@robosilo]

Surface speed is important but so is DOC. You may get tearing and terrible finishes if the tool is barely engaging the material, but see a dramatic improvement once the DOC matches or surpasses the nose radius.

[@EdgePrecision]

I'm going to post a video today on this exact subject. Watch that video when it comes out. You are partially correct. But not completely. Watch the video than tell me what you think.

[@erikslagter3231]

[@danieltong9592]

Videos are still good Peter. Do you still have the garage shop from a few years back when you did a series of videos? My wife is Colombian and I have tried Spanish classes on two occasions, but with no success.

[@EdgePrecision]

Yes I still have the garage shop. But I haven't really done anything in there in a long time. As to Spanish classes. I'm not sure what kind of class you are referring to. I kind of think you are in a similar situation as I am. You hear Spanish, probably every day because of your wife's family. I don't know but if your wife speaks English also like mine. When you are in a situation where you need to use Spanish and you are both together she probably translates for you. My wife has always done this for her mother from English to Spanish. So she does it without thinking for me from Spanish to English. In a way I appreciate that, but it makes me lazy and dependent on her for a complete conversation myself. It would be better if she forced me to use Spanish. For the past 2-3 week I have been studying by myself, watching KZbin videos and using a vocabulary phone app. I have made more progress in my Spanish this way than just listening to it. It takes dedicated study of the structure and as for Spanish the continuations, of witch we don't have in English. This has made a difference for me.

[@danieltong9592]

We live here in Australia, so her family is still in Colombia. She translates to English when the situation comes about. Like you said though, it makes you feel lazy. I was referring to Spanish language classes. That garage shop is pretty cool. I wish your EDM was still there, be great to see a video on it. Understandable though, if it wasn't doing any work to sell it.

[@ryanbaker6059]

Great video, get the fundamentals right and you will normally get good results! Take care of yourself and your family.

[@danwei41]

Very interesting! I wonder what happens when using a different kind of steel.

[@loukola5353]

2:25-2:40 a nice little dig at Titans of CNC 🤣

[@spikeypineapple552]

Hi Peter, I really appriciate your in depth videos, but don't feel like you have to bring out a banger every time. Just a video of you talking about how you do think about doing a job with some video is still better than nothing! Something I always ask tool reps, and they never seem to be able to answer, is why a higher sfm gives a better finish. I understand at low foottage there being some recutting or something, but the actual why I have no idea. Do you know?

[@EdgePrecision]

I can’t give you the exact science behind it. But every tool and material combination has a ideal speed that the tool cuts. I think it has to do with the way the shaving flows over the tool and how the tool shears it off. This will change with material, it’s heat treat and alloy. With carbide you are not cutting with a sharp edge like HSS. Your doing a combination of pushing/shearing plus burnishing at the cutting edge. (Look at the edge of an insert under a micro scope. It’s rounded. Some even have a mico bevel.) So the speed has to be correct to get this burnishing at the cutting edge correct for the material. This is more pronounced in softer mild steels (that’s why I chose that material for this video) than say heat treated or alloy steel. You will also notice in this video how the color of the shavings change as the speed gets correct.

[@peterconnan5631]

Thanks for this. What material is this?

[@EdgePrecision]

I don't know for sure, it came from the scrap pile. Some kind of mild steel. From its look I would say 1018.

[@peterconnan5631]

@@EdgePrecision thank you very much.

[@dopihead]

You should do the same but with an endmill to test for floor finishes. I always get a shit ton of lines (unless the endmill is brand new).. I've resorted to finishing the floor with an indexable face mill. Then coming in and finishing the shoulder with an endmill. I always figured maybe it had something to do with the endmills having sharp corners instead of radiuses like with the inserts on face mills. But I'm not sure.. Great video!

[@EdgePrecision]

What I usually do if I need a good finish on bottom faces is. I will finish the bottom face with a bull nose endmill at a higher speed. Then finish the walls with a sharp corner endmill to establish a sharp corner and the walls. A sharp corner endmill will usually leave the swirls in the finish. Especially in soft steels.

[@dopihead]

@@EdgePrecision That is very interesting, I personally don't think I have ever seen that been done. Ill have to try it next time I need a good finish. You would think that would take forever but if you need a good finish, it is what it is. Definitely would be interesting to see the time taken at different speeds and the kind of finishes it leaves. Hey would make for a great video! Oh and the different step overs too!
