You would probably have foundation issues being it's one and a 1/2 tons approximately. Somewhere...not going back to check. OK it's 1.3 ton something or tuther lacking now the waste. Still it's a lot for a foundation to deal with in such a small footprint. Not to mention the damage caused to the threshold moving it into your abode.
@@krrrruptidsolessyour concern is well warranted, but you're worrying about the wrong thing. I'm gonna assume the hypothetical house we're discussing here has the stereotypical north american base design (foundation poured, joists fixed to the parameter with possible central support depending on span). If you literally ment set this up in the basement directly on the foundation then holmie would be fine. A houses foundation isn't technically all that strong, humanity is just really good at being clever. The foundation is more like an interface, kinda like the fabric of an airbag: on its own it's got limp-dick levels of strength but we found a way to use it anyways. The important number is the soil bearing value which is usually around 1'500 lb/ft², as that's what keeps your foundation up. Technically, if buddy REALLY wanted to he could stand it on end without much worry. Start dimensions were 430×430×1530mm, with 8mm removed per face. So first we get the volume 41.4² × 151.4 = 259'493.544cm³ Multiply it by the density of titanium and covert to pounds. (259'493.544 × 4.5) / 1'000 × (1000 / 454) = 2'572lbs Then divide its weight by the surface area (the "/ 929" is to convert cm² to ft²) Long wise: 2'572 / (151.4 × 41.4 / 929) = 381 lb/ft² Oboist style: 2'572 / (41.4² / 929) = 1'394 lb/ft² So most likely the foundation would be solid... if you'll pardon the pun. Putting it on the ground floor wouldn't exactly be wise, but I'd be lying if I said I wouldn't just go ahead and do it. Yeah it grossly violates code but so long as you're not a moron about it your good. Which basically translates to don't do it 🤣🤣🤣. I'm a redneck who knows some calculus, my structural engineering advice ranks right alongside drunk hobos and used car salesman. That said the reason I'd still go ahead and do it is because I'd have it set on its side, perpendicular to the joists. Assuming 16 inch spacing you can get 3 under it for sure. These joists also couldn't be long (like a 30' span or something), nor could they have a deadload. Also you'd have to be right along side an exterior wall. Having it by the wall reduces deflection and should keep it under 1/360°. As for overloading them... well if you had let's say a 20' spaning joists, the interface between the foundation and the floor would have to be able to support 3'200 lbs of force across 4'... and usually the safety factor is ridiculously generous cuz of idiots like me! (ie. I recently had to use so aircraft cable for a hanging bed. The stuff I got had a rated strength of 180lbs. It had a safty factor of 4, and had a maximum overloaded working limit of 860lbs. But the kicker was it's breaking limit... that was just over 2 tons to reliably break it. Oh ya, and thanks for the excuse to bust out a notepad! I'm not joking, I love little puzzles like these and you made my evening. Cheers man, taker easy
Not to nitpick your work, which otherwise I see no problem with, but I would highly recommend getting four, one foot long sections of old nylon strap or something like a piece of 1mm sheet metal bent into an L shape and slightly wider than the strap to stick between the cut sharp edges of the billet and your lifting strap, I've worked in a large scale industrial machine shop for years where work like this is considered a small piece and I've seen guys drop everything from 40,000 pound finished parts to billet blanks this size after their cut edges sheared through the nylon lift strap. People would actually get written up for not putting protectors between straps and sharp edges, our company took it very seriously. Otherwise this is great, it looks like you've come up with a good (and from what I've read in your other comments very economical at $3.10 per insert) cutter body and insert combo and dialed in your feed rates really nicely, good smooth cutting without overheating the swarf, great job. Cutting high volumes of rough titanium is no easy task, the oxide surface is hell on cutters and the irregular surface thickness doesn't help either. What is this billet supposed to be for?
When lifting 1.3 tonnes of freshly machined billet with a razor sharp edge ... always ue some form of edge protection for the sling, as if it cuts through, it will fall and damage the machine, the block and possibly you.
I just posted the same thing before I saw this, I've seen too many gigantic parts approaching values of supercars get dropped on their nuts from 4 feet up and scrapped because some Deedle-dumb rigger was too lazy or forgetful to throw a couple sections of old cut strap (we kept all our old frayed lifting straps and cut them into sections on a bandsaw, they work great for protecting edges) between a sharp edge and the strap. I once saw a 40,000 pound rock crusher body fresh off the last operation on the lathe and turned upside down get dropped from just under 4 feet, it gouged the cement it landed on but even worse warped the entire top end out of round by about four times the accepted tolerance and destoyed a critical surface, tossed about 400 man hours into the garbage can. The boss was displeased. All preventable with an extra 2 minutes of work.
The single worn strap around the sharp edge was the sketchiest bit. Don't save on them, they cost a miniscule fraction of the revenue of the work :) At my work, we have straps with protective PU-covered sheaths around them, similar to anti-cut gloves.
Synthetic slings are much more durable than people are lead to believe. Not using them on corners less than 3 times thickness of the sling is a strict safety regulation because of the idea that they will be used on loads in the air, in such case there can be absolutely zero room for error. It’s not that they are likely to break when used on a sharp corner, it’s more so that there is zero tolerance for the possibility of it happening. As long as you inspect them before and after use, this is little harm in using them to move loads like this around a shop
@@eggshapedisraelioperative6317 I've never heard this or know if anyone that would condone this as "safe." Not to mention you can literally see the burr as he's picking it up. Unprotected edges will ALWAYS be a no in my book even with slings with abrasion/wear protectors, it takes such a miniscule amount of time to put some cardboard or other protection there. My favorite thing to use is old welding gloves that are discarded, stuff like that would usually cut through one layer of the leather.
That's an expensive bit of metal! I couldn't help but imagine those chips coming off your initial cut as sounding like a cascade of pennies hitting the floor.
Cool, most expensive piece of titanium I've machined was worth $25,000 in the mid 90s. It was a little smaller. But I squared it up on a big horizontal CNC mill very similar to that one. The final part program we ran on a piece of aluminum. One company before us had already scrapped the material and there was no room to scrap anymore material. It would have been months to get another piece. We normally just ran the parts, it's was very common to only have one piece of material to make a part, but the owner said let's not take any chances. I was confident to just make it, but I didn't own the company and I think he told the customer we would run a test piece to prove the process and programming. I'm sure the customer paid for it.
So you had to make the parts out of a comparable chunk of aluminum to prove it could be done before processing the titanium? Makes sense, especially if it was the customer’s second try.
Hey JamesPark_85 Machining TV! That's the biggest titanium machining I have seen on RU-vid! Beautiful horizontal boring machine work! Thanks for posting this cool video! Ride ride ride!
I don't understand why people after watching feel the need to critique this man. He did all this. AND took the time to record. Edit, upload it to the internet. There is 10 ways to skin a cat. Love this!
I personally would have used a katana 3.0 milling tool at a 467 degree angel. Doushing is a must as well! also protractors work far better for checking 90°. Great vid!
I'm in the tree industry but this work always fascinated me, it seems to be endless what one can learn in the maching and tool die industry. I love when people share knowledge and projects like this.
@@jamespark_85machiningtvI believe someone have been misleading you, as some sort of joke. I never never seen a chunk like this anywhere near chip production, I assume it's meant for further processing.
@@_Everyone__ why not? the smaller the things get, the bigger the tools have to be. For absolute precision, you need extremely massive and stable baseplates and so on. I have no idea if this thing is really used for something like this
@@PoisonNuke Yeah but why use titanium with its huge price for some large part of manufacturing equipment. Titanium is good for its light weight which is important in things like aircraft but I can't see the point of using it in a manufacturing machine. (The chemical resistance of titanium is sometimes the motivation but that can't be the case either for such a large piece. I thought of using ball valves in titanium for a chemical process recently but was discouraged when the price was 100 times higher than for 316 stainless steel which isn't cheap either.) It would be fun to know more in detail what it should be used for.
@@skunkjobb hydrofluoric acid and all kinds of other nasty chemicals get used in semiconductor fab. Purity is also an issue. Even thought something like stainless steel may not corrode away quickly, even a few chromium or vanadium ions may wreck their entire process. I honestly don't know enough to know that they do or don't use/need titanium, but I certainly think it's plausible. They also do processes like spin-coating, so this being a very large moving part is also possible.
Big machining energy. Those chips each make a different note as they fall so far and hit a surface which is lovely. Send my regards to your forge that is some choice metal to be cutting into.
I don't know anything about machining but i would love to own a small CNC mill for my projects. You video is awesome and highly educational and also entertaining for me. Don't let other people get you. Quality content and i bet most here haven't even tried to process something that huge who are rantin at the comments.
I have a Titanium Powerbook, it stopped working due to a failure of the screen. Some day I am going to get it fixed, what a beauty that machine is. It feels wonderful, it looks great.
My first intro to titanium was with the triple bomb ejection racks (TERs) we used on my Navy squadron's aircraft in the mid 1960s. The ejector rods, about a quarter inch in diameter, were made of Ti. and they transfered the energy from an explosive charge to the bomb, pushing the weapon away from the slipstream of the airplane. Occasionally we received replacement rods made from steel other than titanium and these would bend and become useless after only a few firings and we would have to cannibal good rods from other aircraft which became a pain in the butt for sure. Made a believer out of me. Titanium is really tough stuff. Almost impossible to damage or even scuff.
That sounds really interesting. What type/how much of propellant did they use? Could they be used at any air speed? I believe the SR-71’s were hogging up a lot of Ti at that time.
Great de- barking job, spent many years doing this for my father,a fantastic guy and teacher for many years (47), what a fantastic daily life with a father and friend,🤓🤔❤️🇬🇧
What will this giant chunk be used for? Breaking it up into smaller bars or one giant CNC-Masterpiece? You could try contacting the Client and ask what they will do with it. Would bei dope, maybe you could even film their processing.
It's a huge piece of metal. What do you do with the titanium? It's funny it looks like stone still you start milling it then you can see the shine of the metal. Do you sell the shavings. I'm in a few Hobbyist Fireworking groups and titanium is often used for a white glitter effect. Although Even those shavings would have to be milled down to a powder like consistency and a little larger to be used in the fireworks process
Thanks for the video, Do you have any info about tool life? With dia.100 tool, that much milimeters per cuttin edge etc. etc. or maybe minutes per edge? Have a nice day.
Nice thing about this material is it's strong enough to go to space and lighter than anything else. All stealth planes have this as the airframe and choppers use it for rotor blades. The shavings are probably worth at least 5k alone.
I would put softners on the sling corner's just incase...my opinon of course...its amazing really how the billets are arc welded in an ammonium vacuum....like how did they come up with this process of manufacturing these alloys...
Wouldn't it make more sense to face the first side like you did and then put that side down on the table so the next side is parallel to the first? How are you keeping the second side square to the first did you indicate it in?
I love how you have this massive block of Ti and expensive machinery, yet have a huge hole in the window, with an existing hole which has been glued back lol
Should never pick up material without corner protectors on those woven straps, you can cut through them in a second on the sharp edges of that material, would have my head if I picked that up that way
I was sure hoping I wasn't the only one that saw that. I've seen those straps cut in two from that exact thing. Those burrs cut them like a razor and that part falls to the floor. Luckily the ones I witnessed no one got hurt and were all only a few inches from the floor
What good brand for drill bits drilling through 5mm stainless steel A2 or sometimes A4 at my workplace? We use dormer jobber here in the UK and seems to do fine but maybe u know a different one, And if a good brand, can they be resharpened and with what tool would suit best? Thank you
Just curious, are the metal shavings ever collected for recycling? Especially with the volume produced in general as well as the value of this specific metal I would think that might be worth it?
Pretty much all metal shavings are collected for recycling because just throwing them out costs money. Stuff like stainless and aluminum or titanium are worth seperating but if it is regular steel most recyclers charge you money for the use of thier bin if you don't fill it frequently enough. Solid chunks of steel are worth more.
I dream of someone just letting me use their workshop with every machine possible so I can just make a bunch of impractical but awesome things. Like who wouldn’t want a full suit of titanium body armor? A full suit of titanium chain mail? A captain america shield. Would be so fun. Pointless, but fun.
