YouTube- Matsuura Maxia: V8 Engine Block Machined From Solid


A couple Qs...


how many hours would it take to design the program to do something like this?

How much actually machining time would something like this take?

[Racey]

If I had to guess it could take at least a couple solid days to determine tooling for each feature and a plan of attack for each feature, maybe a week total between that and tool pathing to make everything just right...

as for machine time i'd guess 15 hours maybe?? there are 2 operations for sure, the part has to be flipped and refixtured halfway through to machine the opposite side..... it's aluminum so it machines pretty easily, and they can take big fat cuts.....

This would just be my guess, i'd like to see what an expert in multi axis CNC thinks about it.

Out of curiosity what would a block of aluminum that size cost raw?

A LOT :D I think it gets exponentially more expensive when you start getting into the odd and very thick plate stock sizes like that...

a block of 6061 24"x18"x15" calcs out to weigh about 630lbs, so even at the normal $3 per pound price it would still cost almost $2,000 for the block.... very expensive motor right there :p

Like watching PORN!!!

RD could whip out a few of those a day no prob. He just has to buck up and buy the machine.

I'm workin on it.. Things are a little rough right now. :(

I assume you mean after you have a drawing of the item in a design program like SolidWorks or similar? I personally know I've put WEEKS into the design of much smaller projects.

Absolutely, there are countless, hundreds of hours put into initially modeling that thing, not to mention whatever R&D went into designing it initially over the course of time :thumbsup I was referring strictly to the tool pathing and plan of attack for machining. :cool:

Exactly,

I have 300-400 hours in the design and prototype in each of my Banshee and SuperJet cases and a much simpler part than the engine block.

I will say, when I see the "Matsuura" machining being done, I see a ton of wasted cutting time. This is the 4th or 5th part I have seen being made and I assume it must be the same programmer because it seems the same MO.

IE: Small cuts, slow feed, 4th or 5th axis being used when only 3 axis is necessary.

It is definitely cool to watch, but there is alot of room for improvement.

See to untrained eye like mine i'm thinking "holy shit that thing is hogging out some serious material" :D but i'm used to running a bridgeport :skull

I'd love to dive into some serious cnc milling and lathing, anyone out there looking for an ambitious intern?:D

Ya know, you might just give a call to Kevin at R&R Prop Shop in Henderson. He's got a big Fedal 30x60x30 and just not enough time to run it...he's a prop shop primarily. I guess he might be interested in an intern to run it. 702-564-7502. Worth a call or a drive by. :)

[brendellajet]

Man, thats just cool. That makes my job as an accountant seem so phucking boring. I picked the wrong career.:skull

If you are making money, I doubt that.

I'm actually having Kevin build me a custom forged cnc'd 2 blade v-drive prop right now. :thumbsup

[STV_Keith]

Yeah, he told me about that...and I told him about this post. Hit him up!

[motormonkey]

Has to be one expensive motor. Cool to watch.

What a good CNC Machinist and a Good Accountant make are night and day. I think your ok in your career choice.

I would probably agree with that statement....but if you WANT to be a machinist and you are an accountant....that is a different story.
