Quoted: I was very upfront about having no experience but mentioned how I am very eager to learn and everything in this field is completely new to me, I just don't want to walk in lost. View Quote Attitude is everything. If a person has the desire to learn, and is willing to listen, you can teach them anything. Take lots of notes. Writing stuff down helps it get in your brain, it also allows you to go back and review it to make sure you understand it. When I was a supervisor and training people, I would show them how to do something on a machine no more than two separate times. If they came back asking again they better be able to produce some notes we could go over and figure out what step they failed to write down. |

You didn't say what the company manufactures or the kind of work they do.
Since they are looking at you as a trainee, they aren't going to expect a great deal from you. Dress more or less like you would if you worked there. Wear CLEAN decent clothing. Jeans, buttoned down casual shirt ( make sure it is tucked in ), and work boots. Don't show up in shorts and sandals. Get a haircut, shave, brush your teeth..... looked groomed and neat. Don't speak like an idiot or use slang, look people in the eye, answer questions honestly, don't curse, act like you were raised to show people respect. Know how to use a scale ( ruler ) and read and give dimensions properly. I once had a kid say " one line past 9 inches" to me when I asked him for a measurement........don't do that. Take some time to look at and learn how to read a 0-1 mic and a set of dial calipers...... both easy to read. Math skills should include simple addition,subtraction, division, multiplication...... fractions and their decimal equivalents..... Trig and knowing how to calculate angles and bolt circles.... some geometry etc. All high school stuff that you should know. Print reading should be simple stuff. Again, since you told them you know nothing I wouldn't expect them to give you anything complicated. Learn what a center line looks like, what a hidden line looks like, what overall length means is, etc. Just basic stuff. Learn some basic machining terms ...... there are several good books available. |

I do a lot of sheet metal prints. We manufacture the parts in house. We are required to put the bend direction (up or down) and degree of bend on a flat layout, that we call out for our reference only because the guys making the parts wrong and bending shit the wrong way despite have front, top, rh side, and iso views on said print.

I can tell which of you actually know what you're talking about and wish I had you in my shop, others still have a ways to go but that is alright too.

He had 2 Coca-Cola crates nailed together for me to stand on so I could reach the handles on a Bridgeport mill; 48 years later and I still pick shavings out of my hair at night.

I have pretty much given up on hiring "experienced" machinists. The good ones stay put, mostly, because they are a diminishing resource. Hell, I just gave my best lathe guy and my best mill guy equity to keep 'em.
OP, your attitude, willingness to learn, and ABILITY TO SHOW UP ON TIME, EVERY DAY, will be the main thing. If you served, you'll know to "Sir" and "ma'am" everybody, but look 'em in the eye confidently. The tests/assessments are as much for you as for them. You will see what you will be expected to know if you don't already, it will give you info on if this is a good career for you. Many shops prefer machinists to own their own tools, as opposed to supplying them. I came up with a starter kit list for new hires, it might help. 0-8" Mitutoyo Absolute Digimatic Calipers (Starett or Brown & Sharpe are also acceptable) 0-1" Starrett Micrometers (think its the T436 1xfl-1) 0-3" Starrett depth mic Good set of files (Nicholson) - set of good screwdrivers, #1,2,3 phillips and flathead set of metric and standard hex keys, preferably ball end Shaviv chamfer knife with assorted bits 6" scale (this has been covered) machinist's square 123 block brass-head hammer torx-bit set Not saying you have to buy this stuff...just something to expect. Many shops will spec the particular measuring instruments they want you to use, we for sure do. Don't go to Harbor Freight. Good Luck! |

Since it appears that we have all of the arfcom machinists in one place, I'll go ahead and take this thread on another small detour.
![]() My drill press is worn out and I am looking at the Grizzly G0704 as a replacement/upgrade. I have never used a mill. Is this a really bad idea or is it possible to learn without formal training? I do have basic/intermediate metal fab skills using a plasma torch, welder etc. Quite frankly I don't have time to take a formal class. Anyone know of any online resources that I could use for the basics of operating the machine? I realize that I'll probably spend the same in tooling and measuring instruments as I am on the original piece of equipment, but I'd like to learn a new skill. ![]() |

I came up with a starter kit list for new hires, it might help. 0-8" Mitutoyo Absolute Digimatic Calipers (Starett or Brown & Sharpe are also acceptable) 0-1" Starrett Micrometers (think its the T436 1xfl-1) 0-3" Starrett depth mic Good set of files (Nicholson) - set of good screwdrivers, #1,2,3 phillips and flathead set of metric and standard hex keys, preferably ball end Shaviv chamfer knife with assorted bits 6" scale (this has been covered) machinist's square 123 block brass-head hammer torx-bit set Not saying you have to buy this stuff...just something to expect. Many shops will spec the particular measuring instruments they want you to use, we for sure do. Don't go to Harbor Freight. Good Luck! View Quote Another take: Some of this is preference. I find 0-6 calipers more handy. Starrett is over rated, nowdays. Mitutoyo is fine for mics. If you find some with a pony on 'em, those will do, too. ![]() Instead of a brass mallet, the Lixie dead blow mallets are tits and weenies. (a note on using a mallet. DON'T PUT YER FOOKIN' HAND ON THE PART YOU'RE SEATING ON PARALLELS.) ![]() 123 blocks should be in a set of 4. You should make them your self, if the shop will allow government work after hours. In addition to the burr knife, a roto-burr is handy. But, you'll see what you need once you get your feet wet. |

Since it appears that we have all of the arfcom machinists in one place, I'll go ahead and take this thread on another small detour. ![]() My drill press is worn out and I am looking at the Grizzly G0704 as a replacement/upgrade. I have never used a mill. Is this a really bad idea or is it possible to learn without formal training? I do have basic/intermediate metal fab skills using a plasma torch, welder etc. Quite frankly I don't have time to take a formal class. Anyone know of any online resources that I could use for the basics of operating the machine? I realize that I'll probably spend the same in tooling and measuring instruments as I am on the original piece of equipment, but I'd like to learn a new skill. ![]() View Quote I haven't actually looked, but I'd bet there is a lot of good machining vids on youtube. As far as paying 1200 bucks for that machine, you stand a good chance at getting a used knee mill in that price range. Take someone who knows what's what to some local machine auctions. Only down side is most of them are 3 phase. Some older/smaller ones are not. You will quickly get frustrated with that little mill would be my prediction. ETA: After glancing at ebay and craigslist, it might be harder than I thought to get a decent deal. ![]() ![]() |

Retired machinist for many years.
It's a great job. Thanks for bringing back old memories and all the laughs. Just don't forget to harden your babbitt hammer by dipping it in the lead pot. |

That would've made my day.
I have a guy who came in looking like a pro for his interview, shows up first day and pushes a beat up rusty craftsman roll-around out of his minivan. It was ON ITS BACK. He flipped it out, made a tremendous racket. Everything in it was covered in grime. He lasted two weeks. I ask about tools now. ![]() ETA: meant to quote Ridgerunner's surfer machinist genius story. |

If their math skill assessment tests are anything like the one I use for prospects it will contain basic geometry, some trigonometry, fraction to decimal conversions and metrics. Blueprint reading is different altogether and is not as standardized as it used to be and should be IMHO. If you have had any technical drawing classes you should be able to stumble through a blueprint reading assessment but that does not mean you will be proficient at their particular type of drawings until you become accustomed to their interpretation. My business is a job shop and we get drawings and models in from a lot of different customers and few of them follow the same format; commercial aviation drawing are vastly different from automotive for example. New hires, usually even experienced ones, always need supplemental training on correct drawing interpretation and geometric dimensioning. Boy that's the truth...... seems like there is ZERO standardization in prints today. I have seen some REALLY screwed up prints. One shop I worked at did not have the surface finish marked on any prints. ![]() Prints from our office require reading the notes, not all information is contained in the dimensions or notes on the face of the drawing. I worked on a big ass weldment a couple of years back designed at a different location. An assembly that would look at home out in hay field, only larger and a helluva lot heavier than you'd find there. Nothing fit when the parts in the assembly came together; the hole diameters were way too tight and none of the critical dimensions in the assembly were coordinated. But it took a few months to get to that point, the location dimensions on the weldments were carried to 4 places so it took a while to get them made; according to the designer's manager, that didn't matter, the tolerance block was controlling. I was at the shop, he wasn't, and he still wanted to argue about the shops inability to build this big ass part to print. The notes might be garbage, however. I've worked with another office that included sheet metal processing notes on drawings for machined parts "in case they are needed". |

Ever use Jap prints? They rarely call out concentricity or flatness or parallelism, etc. even when I KNOW it needs to be there. Their culture is such that you make the part to the best of your ability. It's assumed. View Quote View All Quotes View All Quotes Quoted:

Cuts down on the number of drawing notes, but results in some real trash parts and assemblies, too. View Quote We do a good bit of aerospace work and a ton of commercial aviation. Even prints from the same parent company, just different divisions, construct their prints differently. It keeps me on my toes and requires several cross checks to be sure we have all the processes accounted for and documented. Several of our customers require DFARS flow down charts with in-process and final inspection reports with all the "i's" dotted and the "t's" crossed, full accountability all the way back to where the ore was mined in some cases; if the document contains an error the parts are assumed to be in error as well. Some days I long for simpler times, maybe I'll be a blacksmith in my next life. |
