O/T apptitude test

[David Czerw Triumph Gear Systems]

I'm looking to hire a couple of people, Does anyone have any pre-liminary apptitude tests made made that they would'nt mind sharing. We need help the tool-setting dept.~ day shift and the c.n.c mill dept.~ night shift.Thanks in advance.

Basically what I would do is give them like 10 DIRTY holders, tools, collets, etc... And have them put them together and see what they do and how long it takes them. That's a practical test you can give to a tool setter that will at the most, cause damage to a few collets. But Before that, have them explain to you what they are going to do. Look at the hands. If they appear all scarred up, inquire about it. May be a safety problem tipoff. Make sure you have a drill chuck in there if possible, the reason I say that is because I've seen guys put endmills in a drill chuck before.

Yeah, so?

[Guest CNC Apps Guy 1]

... and wonder why they have a concentricity problem when profiling...

[Thad]

Concentricity??? Gosh, you guys are soooo picky! The next thing you're going to tell me is that I need a flat on the tool when I use a set screw to lock it in.

What's a setscrew????

[mold100]

I glue'em in then hit'em with the burnzomatic: redneck shrinkfit

[crazy^millman]

Can give them a sample part and ask them how they would make it. They tells you alot about their thinking and experience.

Wingsfan,

 

We have a little test that is given to people who apply for jobs in our CNC milling department. If you would like to see a copy send me your fax number and I'll send it to you.

HI

I'd like to see it (the test) just to know where I'M at?!?!

The only aptitude test we do for new job applicants is they have to know how to cut threads/ and taper on a manual lathe. Now days any body can be a button pusher, even my grandma. It seems like the new guys coming out of trade skills only want to work on a cnc, they hate working on manual machines.

[robk]

First thing I do is find out if they speak, read, and write English. Lack of communication can and will be a big problem.

Robk,

 

wouh bout tiyping do dat madder? or ami outs

[robk]

Mayday, I could only wish to have somebody like you in the shop . I will overlook typing. As long as the post is good there shouldn't be all that much typing

[herbert west]

Have'm do something. Like set up a couple of tools or have them explain what these particular tools are and what they do. Do you/they use a torque wrench? Loctite? Do check for tool overhang and clamp placement. Do they reach for the Crescent wrench or the proper wrench? I have rarely seen an operator use common sense about how long a tool should stick out of the holder. Will they use brass or other material to protect a senstive surface? Do they bend the clamps or strip the studs? Do they tamp a part down in the vise? Is their preferred method of locating a part the indicator or the edge finder? Do they indicate the vise? etc.

Around my part of town speaking english has been curcumvented by bi-lingual supervisors and "helpers" so you're on your own on this one.

Have them navigtate a program at the control in edit mode and explain what the program is doing. Do they know their code? Can they stop the machine in an emergency?

Will your insurance cover you if this person hurts themselves before hiring and tries to sue?

I,m sure you, fellow forum member, would be able to slam dunk it

 

When we have an ad for a "CNC machinist with 5 years", it helps weed out the button pushers

 

Right now I only have hard copies, but if you would like to go up against the unemployed of Milwaukee send me a fax number and I'll shoot one your way.

Simple appitude stuff, math operations addition, subtraction, multiplication, division, and my facvoite - the word problems, don't forget to add one with a twist.

 

Also get some mics, and a vernier (not the real one, I can't even read those...) and have a bunch of things to measure.

 

This will give you the chance to see them use measuring tools on scrap before they hit your floor (and pocket book).

 

Ask yourself the question "Would I let this guy drive my Porsche??" If yes, then they are worthy to hire.

[Big B Sprint88]

i make sure they have a pulse and put em on a 30 day trial period... no strings attatched kinda deal.

And add to this the hammer beating on the vice handle as well; but hey, it's all good, especially when the instuctors are setting the example.

 

I almost forgot:

How about those 18" pipes that are necessary to tighten the 3/16" set screws - it's such a tempting thought to put one on the bench and watch them snap the threads.

 

I might suggest a preliminary test!

Have the machinist simply change an R8 collet in a conventional mill (Bridgeport) this view would provide an excellant opportunity to measure intelligence and common sense in one shot.

With an end mill at 1500 rpm and 3" per minute, how long will it take to move 15"? How long will it take at 2500 rpm?

 

Over half our applicants miss this question.

Harry,

 

Save your lips - Andrew doesn't have one.

Send him to the tool crib to get the aluminum magnet. If he comes back with something, Dont Hire Him!.

 

I like the idea of giving him some mic's and a verneer, and have him take some dimensions from some known parts. I also like Jame's idea of giving him "Dirty" collets and holders. See if he's smart enough to know that dirt does not make a precision fit.

 

Paul: I would like to see that test. Can you fax it to me?

Ask them how they would square a block on a manual mill.

 

Don't let them touch your machinery, (even for a test for hiring), until you've hired them. Too much risk.
