I'm not a machinist but I can appreciate the skill level demonstrated. Always a pleasure to watch craftsmen (persons) at work from any trade. Intelligence and ability is a wonderful gift.
The trickest setup i ever did was milling a 2 step internal keyseat. The part was setup in a 48" lathe with a 12 ft. bed using a Bridgeport head mounted on a huge boring bar that was mounted to the toolpost. Wish i had pictures of the setup, but this was 30 years ago. I made 5 of these parts for Virginia class submarines.
Can you provide an explanation for the fixturing practices in the first sequence? Those pins that are being hammered into the part and then the assembly of the fixture. If this is a precision fixture, then just hammering in the pins without a guide could cock them in their holes. Additionally I see that you have to hammer the top piece of that fixture in at 0:16. Looks like you are using two pin holes to constrain that piece. This is an over constraint, where a pin hole and pin slot should be used to exactly constrain the system.
Two dowel Pins press fit is a common way to locate mates.. Sure the dowel pins enter at an angle but quickly find the centerline of the mating hole. You are free to slot your mates.
Brilliant workholding trick! Very creative! However, when i make a plastic workpiece (i work mill for plastic company). I pass over to operator to run job, he didn't listen when i told do not overtighten, and he did overtighten too much and ruin workholder and thread. I redo explain him over again. I wonder if any you have experience often that damaged workpiece and have to rework again? Thanks
I´ve once had the problem with a very fragile aluminium piece. On some older machines at my workplace the vices dont have an indicator how strong it pushes together so you do it by feeling. Well the part was warped after i put it out. But hey everybody needs to get some failures like this to learn from them.
Run Production parts for Allison, have mastered every operation in the Aisle but I feel as if my employer is neglecting my potential for growth. How can I over come this? Started straight out of high school after 2 years of trade school, thanks
Find a new employer. I'm going through this now. Do it now before you end up like me. 20 years/$20. hr... yet I'm the production manager and programmer. Do it before they break your body too.
I understand drilling holes in the work piece but, if the holes need removed? Do you make the base larger for the mounting holes then remove that part of the piece? I ask because I see a few issues or concerns cost wise here. Customer is paying for wasted material, machinist is paying for wasted material plus extra time on said piece. Or is all of that already figured into the overall cost of the "part"? Hope I'm making sense with these questions. Love the video's. Cheers :)
My former shop was one of the most accurate job shops that have ever been. We were known for being micron accurate. We'd hold less than .0001 true position and half a micron flatness with Sip jig boring and standard Matsuura CNC machines. We were bought by Corning. Yeah, that Corning. .0001 is a mile.
Corning Inc. #277 on the Fortune 500 list. The diamond turning division bought our business. They wanted all of it in house instead of having to buy our parts that they would then finish with Precitech Diamond Turning machines. We were the only company in the US that could give them the quality, but more importantly the consistency of quality, that they needed. I really wish Titans was closer to me because I would fit in very well there. Everything starts with a clean shop, period.
As a tool maker, there's something about an aluminum fixture, or what I'm guessing is aluminum by the color, for a tight tolerance application like wire EDM that just rubs me the wrong way. Maybe I'm just set in my ways, but that fact that 6061 and 7075 aluminum has 1.44-2.17 times the thermal expansion of stainless steel just doesn't sit well with me. That and mounting dissimilar metals together in a corrosive environment usually isn't good long term. However, if this is a prototype fixture, I can understand using aluminum. Edit: Erowa and 3R are probably using stainless for a reason for their wire edm work holding products.
I'd love to see a video showing how you clean the machine and all the vises/workholders etc. Everything you are setting up looks spotlessly clean.
Wipe everything down when it comes off the machine every time, wipe down the machine every shift
Look how many likes you have on this request.
And do they have a manicurist on staff?

A Bridgeport head mounted to a "boring bar" mounted to a tool post would be a sight to behold. Wow.
Awesome video for people just getting into the trade thru experienced machinist. Love every video you put out!
Some of those jig fixtures are worthy of a machine shop
Keep it coming love you guys!!!
Thanks… Love you too.
One day, I'm gonna move to Texas and work for Titan. I need to be involved in what you guys are doing.
Does Stuart still work at titan or did he head back to cali?
I'm always impressed by your videos
Barry, since you joined the team I've watched every single video. Love the energy 🤗

Who it beating on the empty coolant drums, tell them to knock it off!

how do you machine the pitbull clamps?

The only work holding I know of is using hard jaws directly or a set of soft jaws custom milled to hold a part.
Awesome video. I'm liking the retention pin style fixture. Never saw one like that but it looks super repeatable. How do you fix the pins to the part?
i have seen you use Solidworks. Is there a possibility that you may use Solidcam?
How do you keep everything so clean?

That's just amazing.
大佬 有有没cnc编程的交流论坛推荐一下
Nice compilation, but the music could be removed and I wouldn't complain.
YOu guys rock.
Looking for a shop plan for a 130000 sq ft building any help?????????????
Well thats five minutes ill never get back

It would be great to go into more communication as to what's going on. And turn that beating sound way down...thanks.
Чудесно видео, браво!
Grip it and rip it! Whack ‘em and stack ‘em! And various other things I’ve heard over the years...
Thanks for the information, but could do without the background audio.
4:19 O_O
Boom
I don’t understand what it’s about
Different work holding techniques.
It’s a fancy ad for Schunk and Mitee Bite
Noice!
Yeah ok... But who pay for this? UA-cam i guess :)
Boom
