Maybe for the generic cat/dog image sharing boards but niche topics like machining are still thriving.

Not sure what else this meme is doing other than actively creating a bigger divide between the genders...

If Red Bull can be successfully sued for false advertising from their slogan "It gives you wings", I think it stands that Tesla should too.

Don't get that card. I used to have it but it would randomly output max volume static... Not a fun experience.

A mindset of quality.

CNC Machines that are built in Japan are so much Mount Betterest than their 'Made in America' counterparts. Even under the same company name.

Visit any shop that requires quality around the world and you'll see Japanese made machines almost everywhere.

Is it surprising that a publicly traded company is going to drive down quality to meet (or in spirit areospace's case - attempt to make) profits?

The union also has clashed with Spirit over whether machinists should ever be responsible for checking their own work. Workers say having separate inspectors sign off on individual work is critical for quality control; Spirit and Boeing executives say that technological advances have reduced the need for separate inspectors in some cases.

Bad bad idea. Do not let machinists sign off on a inspection report. The incentive to hide mistakes is far too great.

Welp, time to run the chicken through the reverse osmosis system too.

Still, I’m trying g to figure out how he wasn’t missed for six days- one of which was a major is holiday.

I don't think it's too difficult... Working to ~~live~~ survive, no time/energy to develop a significant other, a lack of a 'family'. Honestly, from my perspective those traits all seem pretty prevalent. What with all of those 'male loneliness epidemic' being reported.

There's so much untapped potential with a probing system and macros that aren't being utilized at all.

This video demonstrates how powerful a quality machine and probing can be towards a future of automation and simplifying incredibly difficult setups.

What gets me unsettled but also inspired is... This isn't entirely limited to the machine tool or probing system demonstrated on the video. We can do this NOW. Existing machines are entirely capable of exploiting their probing systems beyond their usual simplistic usage (part pickup, measurement). And the only thing really lacking is the brains to figure out all the heavy duty math.

I thought this was an extremely insightful documentary about why "Made in Japan" speaks volumes about quality versus the "Made in USA" counterpart. We as machinists are an intimate and integral component to the quality chain. Look around you, Japanese machines and tools dominate the precision market. Okuma, Yasda, Makino, Mazak, Mitsui-Seiki, dmg Mori (the Mori Part at least). While All American brands with the exception of Hardinge are left as a 'value' brand.

I never really liked the phrase "it's good enough". It always gives the impression to me that they've never really had to put something together and have it perform. I hear this all too much in job shops that make parts rather than assemblies. Never in Tool & Die. Sure, the component has a .010" tolerance but if the machinist was to hold everything within .001 or less, it makes assembly work a lot more consistent and predictable.

The linked video is part 2 of a 3 part video series.

Here is part 1 youtube

part 3 youtube

So what's your thoughts on quality? Does the shop you work at feel like they value your effort towards quality?

Roders are some impressive machines. Wonder what kind of accuracy the machine is capable at that velocity.

The material being cut is PEEK Glass-Fiber 30%. It looks like it's fixtured to a Delrin block some how.. Any ideas on this black magic?

Glue? Threaded from the bottom up?

Running into a dilemma...

I have no trouble ending up with an accurate finished part with really tricky features.

BUT...BUT I can't figure how to quickly develop a roughing strategy. I'm always doing short run items so I don't have many opportunities to be hogging out material repeatedly. So, when I get a 1pc job that needs a lot of material removed, I'm very slow.

To a point, where I'm getting micromanaged.... on roughing.

I'm inclined to be safe and prioritize process stability over Material removal rate. For example in HEM, Instead of doing 10% stepovers, i'll do 6%. In turning, I'll keep DOC down on the bottom left end of recommended specs instead of burying past the insert radius. I don't get off on huge MRR like others, my moment of glory is hitting incredible tolerances on a difficult design/material.

What really scares me is... that a mistake in roughing parameters comes with bigger risk than just "tighten the bolt until it loosens up and quarter turn back". It's the part becoming a projectile/scrap, machine damage, and at worst an injury. Lathe work where I have only a fraction to hold onto and inches of material to remove....

How have you developed a 'sense' for how aggressively you can rough?

Following the prior Lemmy post about towels...

I wash once a week, is that sufficient or need I more frequency?

I used to lug the shipping crate of a case around but I needed all the space I can get in my toolbox. Also tried to make this a one-handed design. Press down into the cavity with my pinky and pick up what I need with the index and thumb.

I'm in a situation with my manager who is suggesting that clock-in starts when the employee arrives to the site of work. Effectively saying that everyone should be coming in 15 minutes earlier than their start time.

The majority of what I read online was about security checks when leaving the premises instead of entering. And the results of a couple class actions seem like the law has loose interpretation.

Wondering what your experiences have been like dealing with this situation. Are you paid for your time traveling on company premises?

For ref this takes place in California.

Only 4 geometries to grind on a broken carbide endmill shank and you can drill out hardened steel.

Some have even argued that because America’s software and internet sectors have been so lucrative, talent has been diverted away from older industries.

Please just say the quiet part loudly. Wages in manufacturing are disproportionately lower than other jobs with much less skill required. Tool and die machinists in socal have wages close to McDonald's/Costco workers.

Sorry but how is grinding a punch form within .004mm, (dis) assembling stamping dies with incredible complexity for 10hrs a day without any procedural error premitted comparable with food assembly... One could put the lettuce before the pickles and no one would bat an eye. Put the wrong die in a station and production halts for hours costing hundreds of thousands of lost profits.

I believe the same can be said about construction as well.

Naturally, making physical goods rather than virtual ones mean less margins but of course the C-level executives must have their billion/multimillion salary bonus every year... Wonder what barrel they scrape all that extra money from...hmmmmmmmmmmmmmmmmmmmmmmmmmmm

If I had to take an educated guess, it is the absurdly immense pressure for academic and career success. Basically through one's entire childhood and early-adult life. A child's day would be something like public school from morning to afternoon and private tutoring after that until night time. Rince and repeat with an ever growing pressure for an acceptance into a highly rated university.

And on top of that, incredible wealth inequality.

So from childhood until death it all seems like constant pressure to become excellent. Seems like life would be hopeless if one struggles with the academics and fails to secure a career.

A total of 39,453 people killed themselves from 2020 to 2022, according to data from the health ministry and the Korea Disease Control and Prevention Agency submitted to Rep. Baek Jong-hean of the ruling People Power Party.

Apparently the party is South Korean so I presume the stats are just for South Korea.
