I'm also curious as to what tools you had to buy. That was not a requirement for us, even though I did buy some tools of my own.

>>5340866
Yeah, where I worked It was just me and two other machinists. Good shit.

I suggest you find a job with some small company/job shop rather than some big company like GE, etc. You will learn a great deal from the experienced machinists you work with.

I worked at a small tool and die shop over the summer and I was amazed at the kind shit my co-workers pulled off on a daily basis. They were so fucking fast It's almost unbelievable. Now all the tricks that I learned from them are being applied here at engineering school where I work as a lab technician. Even though I only worked for one summer I probably know more about machining than 99% of all other engineering students and faculty members on campus. I'm not trying to sound like an arrogant prick or anything, I'm just saying that based on what I've seen here so far.

If you find work at a big company, you will start off as a machine operator, not a machinist. There's a big difference. Sure, big companies pay more and you will get benefits, but at the expense of learning jack shit.

Mah nigga.

Do you plan to work as a machinist after you complete your training? Or maybe study engineering afterwards?

Pic related, a few projects I made when I was in machining school.

It doesn't matter which one you choose.

They're all the same until your third year.

Here's how to calculate the first derivative.

To get the second derivative, differentiate again.

The angle is obviously 45 degrees, or pi/4 radians.

Arc length of a circle is the angle (in radians) times the radius.

Arc Length = R(theta)

= 1(pi/4)

= pi/4

I'm able to handle it because I went to school for machining and I worked as a machinist for a while before starting engineering school.

You will get taught a few things about machining at an engineering school, but that's not even scratching the surface on what you need to know to hold your own in the shop (In other words, nothing).

I'm a lab tech at my school, mostly everyone I've seen here, except for my supervisor and coworkers, knows fuckall what to do when you put them on a lathe or a mill (This includes professors and teaching aides that allegedly teach manufacturing processes).

You will NOT learn machining at an engineering school. If you want to learn machining, go to a trade school.

>you will never be smart enough to be an engineer at nasa during the apollo missions where all calculations were done this way.

>>5209707
Trig tables and slide rules.

>>5207069
but not many people*

To me, smart means the ability to come up with your own shit and figuring things out on your own.

Anybody can learn almost anything given enough time, but not everyone can come up with their own solutions to problems.

For example, Many people can learn how to play song on a guitar, but not everyone can write a song.

>Math, as seen by machinists.

3/8 = .375 because it's common knowledge.

Yes, the vise jaws are steel.
The vise is not all that sturdy. It it's tightened too much the threaded rod's groove will strip. The purpose of the project was to show us how precision affects how well things fit together.

Mah nigga.

No, It's not a bad idea.

I got an associates degree in machining and now I'm working toward a bachelor's degree in mechanical engineering.

You'll be way ahead of the curve when you start engineering school.

>pic related, some stuff I made

>>5186011
No. It's a variable that can be any real number.

Factor and cancel OP.

You will do this when you do limits in calculus.

Alternatively...

What are you people talking about, Just plug the shit in to your calculator.
