Physics Day

[Goober65]

Hey, i konw there are a lot of FIRST teams in the tri-state area, so i was just wondering if there were any people from other teams that are going to great adventure tomorrow for physics day. Just reply back and maybe we can get a group together or something, i know a couple members of team 25 will be going.

Physics day? at six flags? what is this?!? i didnt know about this! im going to Great adventure on the 17th though. too bad for me.

Our class is going to hersey on the 22 of may.

We don't get to go anywhere for biology.

My school goes to Cedar Point for Physics Day on May 15. We get to ride the new ride too... hehehehehe.... 120mph in 4 seconds... I'm there.

My Physics class gets to go to Cedar Point for Physics Day!!! YES!!!

We were supposed to go to Physics Day at Great Adventure this year but the school district didn’t have enough money

But of course they could afford to spend $30,000 on a CNC milling machine for one class(CIM)…

man...we get a lame theme park...we only get to go to michigan's adventure on may 19.

[fast frank]

a few of us from 271 went.

I went to physics day yesterday. I was wearing a blue shirt and towards the end of the day I was carrying a red stuffed animal bird. I was with 3 other guys. Sigh we only got a stop watch while other people got scales with lead weights. Then again that may have been a good thing.

A CNC machine is a much better investment then a trip to Physics Day.

We only use it for about a month in one class. All we do is cut out little designs in wax blocks and that can easily be simulated in software. As far as I know the machine can’t do much more then that with the equipment we have.

See you in line

If it's a proLIGHT 1000, I am quite familier with it. It can do just about anything you want a cnc mill to do, you just have to do it slowly.

CNC tools can do the following:

That endmill can cut more then that blue wax. Yes - you can simulate it in software - but doesn't that hold true for a lot of things? I can also tell you from experience that half the challenge is moving from the software to the mill. Even after that there is a lot to be learned. In the software endmill's dont break. In the software the order and direction of your cuts don't matter. In software you don't need to clamp the piece in place (and in software that piece doesn't fly off and hit something).

CIMs is probably the most valuable course in that sequence, exept for maybe DDP.

I’m not saying CIM isn’t useful, but as it is taught in my school the milling machine isn’t very useful to the course. As students we don’t deal with the problems you mentioned. Our instructors make us turn the clamp on manually before we even run the program so that never becomes an issue. The one time the endmill broke for us the instructor sent the students back to their computers and tried to fix it herself. Also the order and direction of cuts isn’t all that important when you’re cutting a simple design(most people did their initials), which is all we ever cut on the milling machine. We were actually supposed to cut out projects from MasterCAM, but after a student ran into problems getting the program to do what it was supposed to do the instructors decided to abandon that without even giving the student a chance to try to get it to work.

I also realize that CNC can do a lot of useful things, but I had been told that the proLIGHT couldn’t cut much more than the wax or wood without some sort of accessories.
