I'm about to complete my first year at niagara college, and am wondering what software you use in the field. I was using Autocad from 2000 to 2004, and now am using Mechanical desktop, and will enter inventor and 3d studio max some time soon. Also, Does anyone get to use a rapid prototype machine? I tryed to to a rotor with some custom text, but it didnt work out too well https://www.nopistons.com/forums/pub..._DIR#>/sad.png , i think the resolution was fucked with, or it could be the massive amount of glue stuck to the tip.

BBBBBBBBBBBBBBAAAAAAAAAAAAAAAAAAAAAMMMMMMMMMMMMMMM M!!!!!!!!!!!!!!!!!!!!!!!









had to get that out.

Anisys FEA

Fluent

Matlab

Catia (industry standard)

Solidworks

Adams/Car

Mastercam Mill/Lathe9

I was talking to my physic teacher, and he says catia was what he used almost solely. I think i may have to get a disk ripped..........as for the R.P. machine, aparently the rotary was too powerful an idea to grasp, so the software colapsed(thats what the machanic said, i told him i now quite a bit about computers, and he repeated his answer https://www.nopistons.com/forums/pub...IR ) Reminds me of the bmw guys in my class, they cant get over a car that has now true redline.

Physics teacher as in Jim Eden?



If so great guy to learn a lot from...As far as software goes I believe Autocad is a good foundation to start from.



Not every company has the funds to use Catia, knor Unigraphics. If you know your way around solids in autocad, it won't take much to know everything else. Granted someone is mentoring you.

No, this guy's name is neil walker. He works for a company called goodridge landing gear. The guy is a genius though truely. He graduated from waterloo with a 80's average. I would imagine thats freakin smart.



Autocad i have a pretty deep understanding, with a decient understanding of mechanical desktop, and it looks like inventor is easier to use.



Hey, why aren't you teaching here richard. you could make a decient buck.

I don't like putting up with some KIDS!!!that goes there or any college/university.



KIDS = people who do not realize that they/parents are paying a **** load of cash to have someone to help them get a better career.

= people that don't have any respect for other people in the class who are paying a **** load of cash to have someone help them afford a better life and wasting the teacher's time by telling them they should shut the **** up!

Ya thats my physics class......................................









the whole top row of the class plays games all class, when the teacher isn't talking you can hear "clickclick".













grrrrrrrrrr

I've used inventor and alibre. Alibre has good peer to peer networking capabilities, but lacks in capabilities, and functionality. I still prefer inventor over alibre. I've used rapid prototyping machines, and in fact am trying to convince one of our deans to buy a metal rapid prototyping machine. Which is supposed to make really durable strong parts.



- Hand

I use Inventor, it's quite powerful, and very easy to learn. Makes Mechanical Desktop look like the nightmarish pile of patches on top of vanilla 2D autocad that it is.

so true. As for the rp machine, it is toast, so we may get one, maybe not, but if we do it will have the capibilities to make castings .









woowoo! cast aluminum rotors!

screw casting it, Mill it out from a solid billet.



casting is not easy to do, and is very delicate process. Impurities, the rate at which it cools and such begins to be a headache.



It becomes a bigger headache when your part goes boing! and you are left wondering if you fucked up because you went through the wrong parts of the phase diagrams or you got an impiruty in the sample.



CNC milling is the way to go if you are doing small scale runs.

Very much agreed.

Damn I cant wait until I get going with that stuff.



Starting college this fall at Rose-Hulman IT , should be some good stuff.



What kind of cool stuff have you guys made in those programs anyways?

I CNC'd a 3D surface. That was the dumbest thing i've ever done.



That was a waste of CNC machine time, which is big bucks

hhhhhhhhhhmmmmmmmmm...................





cnc eh...............





Sounds good.



Wonder how high you could rev a 13b with the aluminum rotors?

wait im posting as dave



the above post was actually -=drift=-

DRIFT,





Why don't you try to reverse eng housings for the wankel.



I wanted to do this before but the equipment was just being installed when I was there.



I got some housings if you want them...

I forgot, start it off with plastic on a smaller scale



I'm sure you've thought of that

Because if you were to ever to try and sell them you would have to deal with laws and mazda, and royaltys if they would even let you.

I know that



but who's to say that they will ever know knor drift selling it...

I wouldn't have to reverse engineer the housings, just as piston makers don't have to reverse engineer the pistons they use for other cars. really, if you think of it, to make a rotor wouldn't be that hard. the only thing is the cooling that would go on due to the oil inside the rotor not warming up as fast as the rotor would on start-up. i dont think it would be big, but others think that the difference in thermal expansion would lead to cracking. Also, more clearance would be needed, as aluminum expands more per degree of heat put in that iron would. So you think this could work? We should hook up on this one time. Also, where did you go to school? It sounds like niagara.

we use Visualmill / rams gold / master cam for our cnc table mill. and for ALL our 3D work we use RHINO, 2D is a combination of RHINO and cinema 4DXl ( I came from a 3D animation backbground and nurbs/bspline are about as low as I go in the curve level.. also all these programs can interpolate pretty well between eachother using IGES/3DM or ina pinch DXF ( splines ).. just my two cents on a small run & prototype setup..

i was thrown a stick in my spokes. how do i get the bit inside the hole to make the internal shapes?for a minute, i actually toyed with a 2 piece design, with a gap-less seal design.

:note:



dave didnt get brains, its really -=drift=- posting.



you can tell cause the grammers are all wrongziors
