Hi back in 1979 I was a Forman for Celmar a very large moving shop we made things for the government some I wasn't allowed to even talk about. But we had a giant lathe about 60" x 80' came from their navy shop that made propeller shafts . Well I had her spitting 3/4" chips with high speed tooling. Start one cut and run a ten hour shift to be close to the end of cut. I had the set ups for the men then they operated them. Your big chip cuts reminded me . Great company to work for too. Six months there and I became a quadraperectic ROM a dont r cutting exploring my spine. They waned me back but I couldn't do my job. We had planer mills a vbm with 12' table and sunk to floor level and its own extra high roof cut in. Abot 35' tall columns my specialty the big jobs. Used forklift and sledge hammers to set up parts. Oh I was big and super strong not bragging ..

@@TopperMachineLLC Still curious about the total time to hog that much off. Similar to welding where you take and make all the right fit ups for the thickness involve then have to feed three hundred 1/8 rods into the vee. I did this as a novice and always wondered how much time it should be taking. I noticed you let it cool off when approaching final dims. Then used a trial finish cut then measure it to closely match your dimension. I also like the fact that you did not make a center but used a center plate and relied on it to not shift thru out the process. I would have made a center hole and ran the live center into it and reef down on tailstock so it would not move. Good job.

[@alanm3438]

I love the introduction; very creative. I do not know a good chip from a bad one. That crane sure has made lifting easier. Holy smokes.............filled the entire shop. That was a lot of material to remove but you did it. I am sure that it took a lot of time. I am surprised that your cutter held up. Thanks for the video. You did a nice job on the video and the part.

[@camillosteuss]

The good chips should be yellow or blue in colour, as it means that they are taking the heat away from the part(in steel that is), and the shape should be 6`s or 9`s or C`s and S`s, as his were, if they are coming off in those small diced curly bits, its great... Of course, if you dont have coloured chips, it just means that the tool and the lathe arent working at optimal efficiency that carbide can allow for, which means shorter work time for you... The chips in most other materials have their own properties, and the colour should not be considered as an indicator of how effectively you are using the machine... The most important part is the size or better yet, the shape... As long as chips break off in bits of 2-12mm or so, you are having a good chip control... If the chips arent breaking but are curling or making whatever other shape, then you have a potential for surface finish ruination, for jamming, for cutter damage, for injuries to yourself, as that mess can just ``explode`` if caught by the chuck jaw and launch a razor necklace at your body, or it can catch and whip about and shred you like butter or pull you in if it catches you, and then you are done for, or in the best scenario, it can just spit out a mess of sharp ``wire`` at you which will land on your clothes harmlessly... You have seen how the chips here look, the size is less relevant and dependent on the cut depth, it just matters that they look somewhat like these ones here in form... All other factors are case dependent.... And some metals dont even allow the chips to carry the heat away, so even that part of the stated above is case dependent, but such metals and alloys are rare... Generally speaking... Even those curly 3-5cm chips are fine, as they break off rather quickly and arent a hazard generally speaking... One could even say that they are preferable, as they are heavier and fall closer to the lathe, making less mess overall... As long as they break off into nice manageable bits, its a good chip...

I do too, but skill-wise, nah, im no master, im a lover of machines, and was learning all i could about machinery and adjacent fields and topics for last 15 years, on my own... Sure, i enrolled a mechatronics school to get some related diploma, but i was a gymnasium-agronomy college student when i was learning about machines... I never expected to own a single machine, but i do now, 12 of them... Skill is not learned, its acquired via practice, and while the theory is a great tool, its mostly what i have... I picked up mostly used machines in need of restoration, and that is what im doing atm... Sure, i have a few machines that work, so i am gaining skill, but i am mostly an apprentice in skill level, despite maybe being able to teach manual machining theory in school... I am great at tig welding for a self taught ``artist``, but my approach to machining is slow and steady, not only because machines should be used with care and love, but because i lack the skill to assume the deflection and all other factors that happen during machining, at least accurately to a toolmaker`s level... Dont demean yourself, and dont lament the loss of business... Restart it slowly, find things you can make and market online with love and surety of quality... Even if its a side job and something that merely drips in here and again... It will get better over time, and you will refine your catalog of products in accordance with your tools and with what is sought after by the public and is in your work range at the moment... Speaking of God given blessings, the good book teaches that God has only one son, which means that all of his creation is his one son, endowed with same attributes, as otherwise they would not be describable as a singular perfect extension of the will of God... If you love this field as much as i do, all the talents that i have are yours aswell, you just need be open to them and willing to learn how to reveal them... I was amazed at robin renz and people like that, but now i see that i can do the same, even if at a slower pace at the moment... If all is spirit, or as scientists would call it energy, then all has the identical potential and source with which all is one, and if you know of the dual nature of matter, which renders it apparently a particle, while its in fact a wave, you know that there is almost no difference in what science and religions teach, so dont ever falter and be downcast...

Heya! First timer and new sub here! Short introduction: The last 5 years i was doing mostly lathe work and deep hole drilling. maunal and NC/CNC and most parts the size of what you had on the machine or bigger. The piece you used to push the part into the 3 jaw chuck (yes it's good enough and i don't get the people moaning about that either, it's perfectly accurate and no hassle to setup whatsoever...) with the center already in it... Makes perfect sense now that i see it the first time and im impressed that one can even take a healthy cut with it. Great idea! I wouldn't try your approch on a 1,8 ton chonker but ima have such a contraption around for the next time i have a piece in that dimensions. lol Really nice work on the part and the vid and nice to see some healthy cuts on a manual.

While that might be feasible for a larger series production, I don' think it'd be worth the effort for a one-off or low number of items.

I've always used the baseline info for cutting, but was taught to tweek and produce better results. It's amazing how much you can push some inserts and have to baby others. I was nowhere near what I've pushed these inserts to, but I also know what gives me the best chip, tool life and surface finish.

[@ramanshah7627]

Great video! Every time I watch a “shafty flangey” turning job where typically 90% of the starting round bar has to turn to chips, I think about the business opportunity in the steel industry to supply shafty-flangey blanks. It would not be trivial - there are four parameters needed to specify a shafty-flangey blank, so you can’t just brute force it. But the potential reduction of waste is so big that I feel there must be an opportunity there.

I looked at the manual, and assuming you are using the "DJI Mic", it has an option called "Mono with Safety Track" that will avoid distortion with varying volume. And you generally want to reduce the "Transmitter Gain" via the screen of the microphone. Depending on which video software you are using, I can provide some settings to then normalize and compress the audio back to normal volume so that people won't complain about the audio being too quiet.

Get a tool cataloge, usually they have lists with all the cutting parameters, some even have a "how to use them" manual. Every operator has its own preferences on wich inserts he uses, i prefer WNMG for rough cutting and DCMT for finish cuts, others use CNMG for both. And the cutting parameter depends highly on your machine and setup, the machine i used at work i could cut C45 with WNMG inserts Vc180m/s, Ap 6mm and feedrate 1,2mm/U, if i would try that on my lathe at home, she would laugh at me and jump out the window.

The taper is what they specified. I suggested a radius, but it was quickly shot down. Not going to push the argument and potentially lose the job or customer. It's hard enough finding work in this region.

Why do you not treepan and then you have a piece to use not just chips

Still risk damaging the accuracy of the three jaw internal scroll when chucking up on rough stock? Still enjoy the video.
