How To Machine A Complex Part 600% Faster Using Trick Techniques

thank you [Music] and here is my favorite part about a five axis machine [Music] recently we were contacted by a good friend of ours Josh Quintero from Total Industries out in California he just purchased a dvf 8000t exactly like the one we have on our floor [Applause] [Music] it's very hot job for that machine so while his machines getting delivered and set up we're going to help them out by creating the process programming fixturing and proving out the first part so check out how we're going to hold this part notice that we've got a massive dovetail on the bottom of this and the part is just hanging out here in the space we did that for a couple of reasons number one is clearance issue now I wanted to take this stock and seat it all the way down in the box but my problem was the table is so large and the spindle has to come down so far that the spindle was actually going to hit the top of the table because our part actually goes all the way down to right above where the Vise is so it takes up this entire bit of stock now that really only leaves us a couple options there and that's either to use really long tools or we get our Vise assembly up off the table or we just raise the material up itself which is what I did and the second reason is because only holding a small amount on the bottom is allowing us to reach 95 percent of this part so we're going to be able to finish nearly the entire part and then come back and only leave two tabs and we can break this part off with and just clean up the back side and that's going to be great because there's going to be a lot of excess stock here that we don't have to worry about Machining away and if it wasn't for this feature the part could come flying out of the Vise which is going to be a bad day for everybody thank you [Music] now this tool is sounding great now but if you watched our previous video you'll know that it didn't start out that way this just ain't working I tried to use a bigger tool which led to a whole world of problems but through a little trial and error we got to a much more stable process but that doesn't mean we're in the clear just yet because there's a lot of material coming off of this part and later on in this video we're going to be doing some full slotting with this tool so make sure you stick around because I really don't know how that's going to go [Applause] [Music] [Applause] [Music] [Applause] foreign [Laughter] [Applause] [Music] [Applause] [Music] [Applause] [Music] normally you'll hear me say to always do all the roughing passes before any finishing takes place but this is one of those rare cases that you can't do that because if you look at these two legs that stick off the bottom here if we come in and rough that pocket out in between that then they're not going to have any support they're just going to be hanging out in face and we know that if we go and try to finish that floor try to drill that hole it's just going to flex Bend chatter it's going to do all kinds of things that we don't want so we're actually going to leave all of that solid come in and do all of the finishing on the outside profile then we'll come back and rough that pocket and take care of the inside walls yes [Music] foreign now at this point everything is finished except for this inside wall we left all of that solid just for rigidity purposes now we're going to come in and Slot this out bring in our finishing tool and we can actually finish this whole wall all the way down to this Center Groove then we're going to call our roughing tool back up and make a slot right in the center now that's going to leave only these two tabs holding apart then we'll come in with our last operation and take that thickness of these two tabs down to 50 thousands now at that point that's all that's going to hold this part and all we have to do is reach in and snap it right on all right now op one is complete and here is my favorite part about a five axis machine it's that wiggle wobble I don't care if you've seen it a thousand times it never gets old I love tabbing Parts just to see this but the biggest kicker to this is we got a huge amount of material that we don't have to rough on the second side saving a ton of time but that's not really what's important here the important part is getting to see this thing move back and forth so what we're going to do now is just snap this right off build a fixture for a second op and get this part complete so stay tuned we'll show you how we're going to do that might have made my tabs just a little bit too thick [Music] [Applause] [Music] [Music] thank you [Music] well if you take a look at this part we do have some vertical walls on the side so we could technically hold this straight in our Vise for op two if this was the only part we were making but we actually got to make a lot of these parts so I don't want to have to indicate every single one every time I change the part out so that's why I decided to make a simple fixture now this is just a rectangle with some threaded holes in it because these 5 8 holes are perfect for these Mighty bot extensions not only will they hold the part securely they'll also locate it very well and I know eight is probably overkill for this but we got eight holes so why not use them and not only that if we find that these don't locate it good enough we could actually take two of these out and replace them with locator pins but now all we have to do slide this straight on get our allen wrench tighten these up and it should be good to go foreign [Music] [Music] [Music] [Applause] [Music] [Applause] [Music] foreign [Music] [Music] so now our quadrant dead in shoe clamp is complete and it is perfect at least until we send it over to Quality then I'm sure shop cop Travis will have something to say about it as he usually does every time I see Travis it's hey bud this thing's out of spec or it's not intolerance or what other made-up terminology they like to say well anyway as you can see our Op 2 cycle time is only like 10 minutes or something it was really quick because we used the tabbing method we didn't have to rough out all of this excess material now that's going to increase to a life as well as reduce cycle time and now that we've got the process proven we can go ahead and send the programs and all of the tooling over to Josh at total Industries so he can run it on his dvf8000t if you want to see more on this part I'm going to be uploading this to my profile on cnceexpert.com while you're there you can get certified on CAD Cam and CNC and check out the global Gallery where you can see Parts like this from all over the world it's a platform for Machinist by machinist so make sure that you go and check it out well I hope you guys enjoyed this video let us know in the comments what you think of the tabbing method and if you use it in your shop don't forget to like And subscribe and hit that join button we'll see y'all next time I can run my printer from my phone I don't have to be in front of it look at this bar we're making So today we're going to be going and running on our dvf 5000 I can't wait to run this far because it's going to be so cool
