Problem- What 3 Questions Would You Ask To Establish Fanuc Skill?

[CNCJobs.Org.UK]

Hi

I recruit specifically for the CNC sector in the UK

Some of my clients take it on face value when a candidate arrives for an interview and claim they can Programme using Fanuc controls.

If you're an experienced Fanuc CNC Programmer I'd be interested to know what key questions I could ask a candidate to really establish their Programming skills

For instance I'm looking for a CNC Turner at the moment. What 1 Question could I ask them so that I knew they're going to use the correct offsets to get the right finish on some F51 and F55 Super Duplex rather than create scrap?

Any help much appreciated

1. where did you worked and with what Fanuc controls?
2. how to check information provided by you?
3. can you start to work with Super Duper F11 and F15 machine tools controled by Fanuc without making crap?

Have the client give you a very simple turning program. Face, radius, od turn, maybe a step. Then a simple canned drill cycle. Give you the cheat sheet, give the applicant just the program. Make him/her go step by step through the program and explain what each one does.

Get a piece of material thats been turned, and a Micrometer. Have him measure it and give you the results.

Simple math test, as well as decimal point test

None of this will guarantee anything, but will at least prove they have been in a shop.

Thanks underthetire

Do you know any questions I can ask over the phone?

Because of the distances involved it's not always possible to meet my candidates

we used to give our candidates a small test. it was a fairly simple sample program but contained errors like a curve/rad but the G0x was the wrong one (G02/G03) or the I sign (I, I-) was wrong, and a G0 instead of G1 etc. If they are any good with programming they will pick up the errors. Also a simple trigonometry test where there's a shape that contains several triangles and they have to first find the triangles then solve them. Again any real programmer knows how to solve this kind of problem.
You could email the info to them and they can complete it while on the phone......

I say we 'used to' do this kind of test. since our company was taken over by a larger multi-national multi-cultural corporation we employ any old dog that comes in off the street to shelter from the weather. 99% of the people who work here don't know jack about programming. I call them 'button-pushers' :/

That sounds like an idea I could use!!

My next challenge would be to get someone to write the tests for me

Thank you very much

I have a copy of our 'find the program errors' test somewhere. I'll try to find it.
For the other stuff, just give a simple drawing with a couple of tangents and some triangles that fit and ask them to solve the tangents. I could give you some example details here but googling would find the answer here easily

Or even easier just say you have a right-angle triangle with angle 'b' at the bottom (something degrees) and longer side B (something length) and ask for the shorter side length (side A). You need to provide the 'something degrees' and 'something length' of course and you need to know the answer prior to asking

i.e.

 |\
 |a\
B|  \
 |   \
 |  b \
 |-----\
   A

also ask for a program to make a simple stepped shaft.
Give them material diameter and length.
Say one step is 25mm long x 25mm dia.
next step is 35mm long x 35mm dia.
dont worry about chamfers etc.
just a simple stepped shaft.
write the program with G71/G70

|                 |------|

etc.

That would be great

Thanks very much

My client just paid £4k to repair the lathe danaged as a result of a Button Pusher forgetting a Y Axis (I think)

Took 3 - 4 Days to rebuild 5 Days to get the Material again and now they need to find someone to do the job properly (which is where I come in

[fordav11]

I gather you have no CNC / Programming experience or you could write these tests yourself?

[CNCJobs.Org.UK]

This is true

I've worked in Engineering (Pierce and Blank Tooling Manufacturer and Sub Contract Machining) and in then in Technical Recruitment for over 20 years but I'm not a trained engineer or a CNC Programmer

[fordav11]

hmmm, that makes it a little difficult for you to properly evaluate people. You will need local access to someone who is a CNC programmer to check the answers because subtle differences can be ok sometimes.

I found our test on an external backup hard drive. I has been a while since I have seen it and I remember now what it was for. It was to stop machinists whinging that they should be paid more (the machinist with programmer skills rate) when they claim they are doing programming on the job. We say do this test and if you pass we'll pay you the rate.
This gets them every time because they fail miserably then they (reluctantly) shut up

However I can't give it to you as-is because it's an in-house patented part with associated copyrighted drawing.

But fear not. I have made a new test for you. I won't post it here because it can be found with Google and you really need to keep this private, especially since it contains the answers also!
Send me a PM with your email address and I'll send it to you.
