JustGav Posted May 21, 2007 Share Posted May 21, 2007 There was a similar vid which did a W12 VAG lump, just as impressive... I could sit for hours watching a milling machine. Quote Link to comment Share on other sites More sharing options...

steb9780 Posted May 21, 2007 Share Posted May 21, 2007 Hard way? That looks like the easy way to me! Yep definitely looks a slider. Saying that on some of the 5-axis hard metal machines at work they are making some big titanium JSF frames, they take 155 hours to machine each apparently.

JustGav Posted May 21, 2007 Share Posted May 21, 2007 Bizarre open-ended question, what is the cost calculations for machining? Just thinking out the box, for example, if I provided a CAM diagram for a valve for an a-series, what would machining them cost? Quote Link to comment Share on other sites More sharing options...

TLicense Posted May 21, 2007 Share Posted May 21, 2007 We've got a Matsuuri 5 axis machine at work. It just doesn't get used as it's not all that accurate. I think it's because the bed is moving, it loses it's datum's. Probably an issue with the encoders. You can buy a good 5 axis machine centre for about £40k. How's it programmed? Well it more or less programmes itself. A design engineer would send the 3D model to a cnc programmer who would set up different cuts. Each different cut needs to be "programmed" if you like, but really it's just a case of clicking on a tool that you want to use to cut, and then picking faces off of the 3D model to tell it to cut those surfaces. We get LOTS of metalwork done in this particular way (in fact I've got to send out £120K worth of metalwork tomorrow, that will done exactly like this) It looks cool, but isn't particularly trick. Rapid prototyping, now that's REALLY cool. http://www.alphaprototypes.com/videos/FDM-Video.wmv Quote Link to comment Share on other sites More sharing options...

danny_silva Posted May 21, 2007 Share Posted May 21, 2007 i work with fanuc sistems!! matsuuras milling and turners!! and its not that easy!! but good money!! just visit Perfectbore.com racing pistons and liners!! Quote Link to comment Share on other sites More sharing options...

danny_silva Posted May 21, 2007 Share Posted May 21, 2007 to set a cnc its not that easy!! 1st you have to see if you have enough material to do want u want!! 2nd you have to see all your tools and correct inserts!! 3rd you have to do a prog, starting by finding your zero positions!! Z0 and X0!!(in a turner cnc) on a 5 axis cns you have... X;Y;Z and A;B( on matsuura) 4th you and to "tell the cnc" were your tools are!! by setting them!! to set the tools, you have and touch on the surface of the material!! them just have to know want u are doing e just make sure that the tools dont crash on the material, or you can put the machine out of working order!! do the prog and run it!! once the 1st piece is done, save prog and ist ready more!! its easy!!

Chris Wilson Posted May 21, 2007 Author Share Posted May 21, 2007 The 1st one is the BIG DEAL, if that works out fine, the 2nd to the 10,00th is dead easy, just throw tools, material, machine service and a bit of operator time at it. but the 1st one is the expensive *ugger Looks like a mega expansive sales pitch jobbie to me! Ultra cool nonetheless. Quote Link to comment Share on other sites More sharing options...

Aye, it's not like the old days programming on tape reels and the like, is it? Trying to remember all the machine codes. We bought our Matsuura to machine gearbox maincases. We then did a deal to get them made elsewhere. (If only purchasing/production would talk to marketing eh?) When the guys in the full size machine shop heard that we were going to buy a 5 axis cnc machine centre to be able to machine bits for our wind tunnel in house, they tried to palm this off onto us. When we explained we would want an off machine surface finish of less than 0.4Um Ra, and profile error less than 0.05mm over a 700mm long profiled component, they told us not to even bother trying it. I'm not sure what we're getting instead. I'm sure I'll be the last to know. As far as I'm aware, the Matsuura just sits empty and unused taking up space. No doubt we'll end up flogging it for next to feck all just to get the space back Quote Link to comment Share on other sites More sharing options...

Ultra cool nonetheless. It's not the machining the first one that's expensive. It's re-machining it because it's been up-issued by the designer as a hole needed to be 2mm to the left! No right, No left, Actually probably be alright where it was. Quote Link to comment Share on other sites More sharing options...
