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.

Most of the math (Should be) basic math with algebra and geometry. Understanding units (Inch/Metric conversion) and scale. Blueprint reading is exactly that, someone should show you some basics, but who knows how much they expect. Understanding a orthographic layout I'm sure is a must, along with understanding view call-outs, like detail and section views.
I'm sure you could Google and learn some of this online on your own. Understanding the difference between a distance versus an offset versus scale would be of some help. Since dealing with offsets is basically what you will be dealing with all the time. Just a fyi that they would expect you to understand is "machinists" lingo is everything is based on a "Thou" or thousandths of an inch 1 thou = 0.001 10 thou = 0.010 100 thou = 0.100 1 tenth = 0.0001 Just about the opposite of what you learned in regular math classes from a lingo standpoint. |

Hello,
Wear closed toe shoes (steel toe boots preferably) and clean jeans with a button down collared shirt. Bring your own eye protection and put it on without being prompted if you go in to the shop. Don't wear any jewelry or a watch. Don't check your phone during the formal interview or informal shop tour. Don't have long hair or baggy sleeves. Math: previous poster covered the basics. Know your inch fractions and their corresponding decimal values to an eighth if you can. Perhaps go by a pawn shop and buy an inexpensive dial caliper and an 0-1 mic and familiarize yourself with their use. Good luck. A lot of it is just showing up on time, peeing clean, and demonstrating an ability and drive to learn. |

A math and print test could run the gamut.
Could be as simple as knowing decimal/fractions and reading a scale, mics, calipers. Could be applied trig so you have to figure a dimension over rolls given a sharp corner dimension of a tapered part. Or, finding tangent points of intersecting arcs. Print reading could be as simple as "find the OAL of this part". It could be "Explain the difference between first and third projections", "Explain geometric tolerance" Basically (and it sounds like you have done it right) Don't try to bull shit your way through a machine shop. You won't. An assessment could be just a tool for them to know where/how to place you. |

Sneak up on a dimension or you killed the part.
How to hold a part so you don't have a, " Oh Shit when you flop or do the other end." Shimming a part on the surface grinder so its flat when your done. The list goes on and on. You wont never learn it all. If you think you have, load your roll away on your truck and go home. Your done and wont be much help to anyone else. |

I have yet to see someone use it for a good short cut my little old English mentor showed me. Place scale on mag chuck. Place angle plate "upside down" next to scale and turn on magnet. Place workpiece on plate and let it slide down to rest on scale, making sure one end is shy of edge of plate. C-clamp in place. Undo chuck. You now have a workpiece that is about .02 proud of the angle plate and true, ready to grind the first edge. (Side against and side parallel the plate are already ground). When they get to "finger nail cleaner and coffee stirrer", you know you have a seasoned veteran of a tool maker.

Show a keen interest to learn on your own if certain prior-knowledge requirements are missing from your repetorie. Yup. Knowing more will help, but a LOT of machine shops will hire without any knowledge. They can find a spot for you. It might be shipping, cleaning machines, and sweeping until the other machinists have a couple minutes to show you something. |

I started off running a manual lathe, rotary broaching parts in 1000 piece lots.

Quote HistoryQuoted: That's a good one. Another is to hand them a 1" mic and piece of round bar. See if they hold the mic properly or if they act like they wish they had three hands. I'm currently teaching machine shop. After observing some of the students, I confiscated everyone's digital calipers. It was pretty obvious no one was going to actually learn how to read a mic as long as they could use a digital caliper. |

Make everything +.001 -.000 and let them measure with whatever their little hearts desire

We damn near had to confiscate them from the Industrial Engineer the company hired as an inspector (Owners son). He was rejecting parts because he did not zero the damn things correctly. 
When I left he was still trying to implement that lean manufacturing black belt shit. He said we were wasting time by finishing all shafts on one side, then finishing them on the other side. He said we needed to completely finish each shaft, one at a time.
This was for manual AND CNC. |
