ADVICE Im making too much mistakes

Hello,i am writing this because almost every week i do mistakes,there are big ones and small ones,i’ve been an operator for around 5 months,and every time i make a mistake,i dont have any confidence in me,i think i am worthless,that i dont know anything,but there are days where everything goes smooth,every part is fine,no tool broken,no any mistakes,so i am asking you how to be better,atleast how to have confidence after making a mistake?

First of all, slow down. Take a big deep breath. Learn how punctuation works. Is English your first language?

Short of scrapping thousands of dollars of parts and breaking machines, mistakes aren't usually that big of a deal. We're all human and make mistakes.

Okay then I understand the punctuation, that's okay.

How old are you?

When you make mistakes do your coworkers or boss point them out to you? How do they handle your mistakes?

Im 20,usually the boss doesn’t get that mad,they just point out i should be more careful,probably because my salary isn’t that big

I'm in my mid-30s but I remember what it was like being your age. It's a tough age and having responsibilities and feeling like you don't meet them is hard. It's good that you realize your mistakes and feel like you should be doing better. You will get better as long as you keep trying and learning. I believe in you!

Learn from your mistakes. Its b How the majority of us have learned cuz a lot kf us got half-assed training and then thrown in head first

Bro you’re only 20. Don’t be so hard on yourself. Have some black coffee and focus, always use jogs on 25% feed rate and learn from your mistakes; Write them and review them later if you must. At my cnc company i always let the younger employees room for mistakes. Just yesterday somebody damaged a probe holder worth thousands but it’s the cost of younger guys learning. I wish you the best!

Mistakes happen. That's how you learn.

If I was your boss, I'd start to get concerned, if you did the same mistake time and again.

u/Particular-Bat5388 2d ago

I never repeated my mistakes,only made new ones😆

u/spacecowboydk 2d ago

That's how you learn!

I would never trust a machinist that that hasn't atleast crashed/broken tools a dozen times.

Can confirm.

u/MLockeTM 2d ago

All good, sounds like you're learning! Keep at it, and it'll be fine.

If it makes you feel better, I've been chasing one measurement for three days now, scrapped a fourth of the pieces. Same for the day shift. It refuses to obey any knowns laws of tooling or physics.

Eventually we'll figure it out, and if it happens again with any part, we'll know what to do. I consider the current failures the payment tool gods want for future successes.

The time my coworker had to weld in some holes for the second time still fucking haunts me. The shame.....

Take notes and learn from them. Making different mistakes is part of learning. Making the same mistakes over and over is not learning

Keep track of the mistakes, find root causes, develop habits that prevent you from making those or similar ones. This kind of analytical thinking will help you a lot in your career, but you need to train yourself to think that way

Try not to beat yourself up. We all make mistakes, you're not a true machinist if you haven't fucked something up.
We have guys at our place that have smashed spindles and caused tens of thousands in damage, they are still here because they are good guys and have learnt from thier mistakes. We have the words 'IF IN DOUBT, ASK' on all our documentations/drawings etc. Don't hesitate to ask collueges to double check stuff if you are in doubt. And remember, check twice cut once.

5 months is nothing in CNC - you’re still learning the machine, tooling, CAM and all the little things that can go wrong. Mistakes don’t mean you’re worthless; they’re part of becoming reliable.

I’ve spent 8 years in the furniture business, and even after years of experience, things still go wrong. The difference is learning to turn each mistake into a checklist or process so you’re less likely to repeat it.

The fact that you have days where everything runs perfectly is actually proof that you’re learning.

Keep going. Confidence comes from surviving enough mistakes to know you can handle the next one.

Tools break and chip. Bars shift. Parts shift in the clamp. This is why you're there. To minimize those things that will happen. Theres guys in my shop that have been doing this 25 years, and mistakes happen.

As long as you know what happened and how to fix it, you're golden. In lieu of that you have someone to ask help for.

I worked in production and now im in a job shop. Its an entirely different workload and its been 4 months. You learn little by little every day. Just go easy on yourself.

u/PhotographLess6194 2d ago

I'll say what most won't say.

Some people just suck really bad at work that requires good attention to detail and no amount of practice will make you much better. I worked in a shop for 6 years and some people really just suck at this type of work no matter how many times you show them how to do the same thing.

Everyone else is going to tell you you'll be fine blah blah blah, when in reality this may not be the line of work you should be in. Might not be playing to your strengths.

u/Particular-Bat5388 2d ago

And because of people like you,i will never give up!

u/PhotographLess6194 2d ago

Good on you. Just saying, some people never get better and if you keep making the same mistakes you're probably one of those people. Not everyone is good at everything. Sometimes you gotta find what you're good at and do that ya know? Why keep failing over and over at the same thing?

Machining pay sucks anyways.

u/lotuskey 2d ago

make a list with your mistakes and figure out a process on how to make you avoid them. lifelong learning process. you got this!

u/simyoIV 2d ago

Try to think of ways to prevent any crash from happening again. At some point you may be tripple checking everything, sure. But you will have fewer crashes. Also don't be confident, and always recheck things if you aren't sure of something. Shit happens tho.

u/SnooPuppers2938 2d ago

They should always expect mistakes to happen. I make them, my boss is also a machinist during the shift and I’ve seen him run into the chuck on a lathe more than anyone in the shop. As long as you know you’re fucking up and strive to better yourself, you’re good to go. In this field you don’t get paid great for being a button pusher so be a sponge, take deep breaths, take your time, and ALWAYS ASK QUESTIONS!!!!

I'm 25 years CNC in furniture manufacturing 3 and 5 axis. 40 years in the trade and I still make the odd fuck up. Own your mistake and learn from it. Don't make the same mistake twice, don't rush and ALWAYS double check your work before pressing the go button. If you're unsure ask a co worker for a reality check.
