Very true. Besides that, not everything is automated... Yes, a lot of difficult, and standardized parts are CNC'd now-a-days, however, there are still applications where a unique, custom, only one to be made, parts still are required. A good example is creating a jig or fixture which will be used to secure a part in a CNC. It makes zero sense to spend time drawing, reviewing, coding, optimizing, etc, if all you need is one which suffices. Furthermore, as you mention, just because you stick your CAD drawing into SurfCAM and generate some tool paths and some M and G code, doesn't mean that it will work all the time, or even at all. One funny example we used to run into in school was that we would generate our paths and M&G code in CAM simulation software without taking the jigs/fixtures into account, and NUMEROUS times rookies would run a diamond tip bit through the custom jig which we fab'd, as well as the stock fixture in the HAAS CNCs, costing several 1000$ each time it would happen. Not only do you have to replace the bit and the fixtures, you need to check the spindle bearing and alignment, as it is almost always thrown off with an unexpected side load, completely defeating the purpose of machining on a CNC--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------EDIT: even when I go back and try add paragraphs it tells me to fuck off :(. This just started happening and I hate making walls of text

What velocity do you think a tool holder flying off a turret while hitting a chuck in rapid at 5000 rpm is going to be?

Faster than bullet proof glass can stop it

I've never seen any actually fly off, but I've seen someone severely damage the internal bearings of the tool spindle, rendering the (4axis) mill completely useless. You can definitely still fuck shit up on CNCs. Too many picture someone standing there watching the mill machine the easiest part known to mankind, while only having the place a new part in, and press the red button. That does happen, don't get me wrong, but not always. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ In my experience, just the tool holder itself weighs in around 5-10lbs, and then the tool coming in around 1-5lbs. Those same objects, like you mentioned, can easily be spinning at 5k rpm. We've milled 6061-T6 aluminum at 30k rpm.

a machinist is not a welder . . . . welding is art . . . machinist is monkey work. . . . imho . .and ya welding skills are in high demand at least ones that can weld and not steal from homeless people at same time
i've actually mastered both. there is A LOT of thinking involved in programming. once the program is written and the machine is setup then yes, it is monkey work. getting there requires some engineering skills. who is stealing from homeless people? :?

Machine system fault. macro variables registering then reverting to prior job variable offset
window 2500
tool holder 450~
tool + insert 90~
Aluminum jaws 100
2 days realigning turret and loss of production

Mazak is paying for the repairs a tool holder and fixing the bug. But not the time off or the shit stain removal from operator's pants

The dirty

Would definitely not be a fun way to go. And yeah, CNCs are EXPENSIVE. We had a few 1,000,000$ at the asu aerospace fab. Everything from 3,4,5,6 axis mills and lathes, to grinders, etc. The 6 axis mill is disgustingly awesome. We use to cut boat props and turbine/turbo fans just to watch that machine do some beautiful work.

I'm getting a boner thinking about that

i used to run 4 different fadals and a bridgeport. i'm at a welding job now. i miss my machining days. it was very challenging. we have an old manual brigdeport and a lathe at the welding shop that i mess with now and then. it's some old school machinery though. i recently tore the bridgeport apart trying to fix the worm feed. for some reason it won't stay engaged. i think a set screw is lose but i can get to it.

companies are holding back their own position from being filled. Machining in America isn't what it used to be. Companies complain no one will fill their spots and then export metals to get machined. maybe if they provided on job training and gave a decent dollar, they wouldn't have empty spots in their company.

Well I say fuck unions. I'd rather go back to a one man show than fucking entertain that kind of bullshit in my shop. I'll just keep it all and say fuck creating jobs for someone who's just going to try to dig deeper into my pockets than what their labor is worth. 50k to work in a factory making shitty donuts and cupcakes. Holy shit, did they have to suck cock too or were they just getting paid that for the donut gig?!

There had to be massive BJ orgys going on cause they had to be earning it some how.

I always wondered how they got the "filling" in there.

Here is it, the magnanimous, ever patriotic "job creator" who only employes people because he wants to "do his part" - oh but no more, he won't hire any more and may just fire them all because they are ungrateful for his largess and his caring.


What a load of crap. If any businessman hires someone for any reason other than fattening his bottome line either directly or indirectly now or in the immediate future, that busisman is an idiot. There is a healthy segnent of Rightist business owners who actually attempt to convince others that they are doing all of this out of the goodness of their own large hearts and if they are too tempted, they will stop... There now "see what you made me do?".

This sort are a lot like rightist gun owners who carry their guns around claiming that they are potecting MY rights. Get out of illusionville and quit with the sentimental sactimonious bullshit. You hired those you hired so you could make more money - nothing at all wrong with that, it is as it should be but don't tout it as your humanity shining through.

Percussive maintanence:


Years ago I heard a new spin on a very old explaination of why folks get paid what they do. I spoke to a "3 bananna" IBM tech, he was the guy who smoked cigars in places where no one was supposed to smoke, he was the guy the called when no one else could get it right, he was the guy they called when it was PAST time for the machine to be up - and these machines were huge temples of the computing priests back in the 60's and 70's. He had a rubber mallet in his tool box and I asked him about it while commenting that guys with tools shouldn't be getting paid nearly as well as he obviously was - smoking habanas in a computer room - what does a computer tech working with delicate electronics need with a hammer anyway. He replied "A group of guys watched me inspect a machine (IBM 1402 I think if anyone was interested). I circled around the machine, I sniffed it, I felt the vibrations in there and then I found just the right place and smacked it with my rubber mallet. It booted after that and all was well." "Then one of the guys wanted to know why they should pay me $6,000 dollars for ten minutes work and a smack with a hammer - why anyone could do that he complained" "No, I said, I only charged you 10 dollars for the hammer smack, I charged 5,990 dollars for knowing where to smack it.

Bakers are working with living things, variable moisture content, vagaries in the air, changes in PH in the ingredients - equipment changes over time, faulty ovens and god knows what else, and yet they turn out the same product time after time, they turn out that product regardless of the situation in the shop, regardless of the dynamics of their crew and regardless of what extra shit management puts them through. Baking is still as much art as anything else and it isn't the buttons they push that warrent their pay it is what DOESN'T happen that gets them the money the deserve.

I was just giving you some abuse, Id expect nothing less back tho.
if you want message me the abuse.
I actually respect you. And wont quit giving you shit. I wonder if any of mine got deleted.
I made mention of drunk leprechauns and puddles of vomit
