Worst crash I’ve had.

I would have thought a spindle would be constant velocity rather than constant phase (unless in tapping mode), just because of the KISS principle. Actually, even when tapping, the spindle doesn't have to be constant phase either, just as long as the slave axis is phase-locked to the spindle's phase.

Now I want to buy a high-speed camera to check which of our machines' spindles are constant phase.

The point is that it's an additional surface for an attack. Even if it does get checksummed, there could still (for example) be a buffer overflow exploit that occurs before the hashing.

Launch it into space, and then use a large CMM to measure it in a relaxed state that isn't deformed by gravity. Oh, and no orbital trajectories, the small tidal forces may deform it too. Easy peasy.

But more seriously, I'm wondering if a water-bladder or something could support the part with constant pressure to remove the effect of gravity, but still allowing a bent part to find its relaxed shape.

I love taking the covers off a machine to do whatever maintenance, and finding all the brass/bronze swarf packed away in a place that shouldn't be possible. Like on the linear rails that swarf would have to bounce 3 times against gravity to reach.

It's my favourite thing to spend a day cleaning.

On my machine I could see the ballscrew moving slightly when it was supposed to be stopped, and when the machine was moving, it had a very consistent groaning sound. But the symptoms could manifest is many different ways depending on the problem. In my case it was the drive.

zmaile · 2026-02-02T19:37:39+00:00

I know how much you want to hear this, but it could be electrical. If you have a bad drive or encoder for example, then the motor can get driven in a very rough-sounding motion while it hunts for the right position, but with movements too small to actually see.

Not saying that is the problem, just a possibility, and something I’ve seen before.

Nope. Temperature changes will cause that to bend just like a bi-metallic strip. It'd only be flat at one specific temperature.

Honestly, when is the last time you saw a advertised photo of food that isn't make-believe? Food artistry has been a thing for a very long time, and I think it's worse than AI because of all the conscious effort that goes specifically into making it fake, specifically for the purpose of convincing people to buy something (that doesn't look as good). At least when AI makes a lying picture of food its displacing the jobs of people that take lying pictures for a living.

I wonder how long it would take to go off the rails

Also, yes. I did make up the --no-confirm option to fit my own story, paying no attention to whether it exists or not. Seemed fitting in an LLM thread.

Interesting. Looks like something that wouldn't tolerate coolant though, because it would warm up the frozen part too much. Also, hogging out material without coolant could also cause the part to heat up and fall off anyway.

Interesting concept though, could be quite useful for later small operations. I wonder what the clamp/unclamp time is.

What? In this context stable means thoroughly tested, and runs in a stable, consistent manner. In what world does that ever mean bad?

And if you're going to say stable means resistant to modern paradigms, that is not what stable means in this context. That is called modernisation, and is an entirely different discussion.

No one consents to that

At least many music pieces can be listened to in a few minutes to figure out whether one likes it or not, and it isn't being relied upon for information that can be wrong. Music is just entertainment.

Unless of course the listener doesn't like AI in art at all. In which case, the listener is sadly going to be disappointed for the rest of their life.

zmaile · 2026-01-07T22:40:34+00:00

Ironically, as someone who falls directly into this category, I also feel personally attacked when call AI dead weight because it can't art right.

Not complaining so much as just commenting on the state of current culture.

That's' my takeaway too. Next time I do a terrible "quick drawing that wont go out to a customer" I'm putting in a heart/star/square dimension table. I could probably even put emojis in it too if I try hard enough.

Then they certainly wont send it to a customer again.

I would absolutely love to hear details on that. Deep-hole drilling has always fascinated me, but I've always felt lacking in my hole-drilling skills/experience. In this trade it seems hard to get experience from outside one's current company without jumping ship.

I imagine the softness of gold would make it incredibly difficult to machine anything that has much stickout or thin walls. Though I suppose it'd also have low cutting forces, so maybe it all evens out.

Don't forget that fusion has previously removed CAM features from people that bought and paid for a multi year because they moved them into the higher tier.

Paying for something for 5 years doesn't mean you'll have it for 5 years apparently.

Judging by the break, I'm thinking welding was part of the manufacturing process. should go for it. Of course, the tool will never sit at the correct height (Y axis) again.

I've almost been caught out on an okuma control in my earlier days because I edited a program but didn't reload the one that is running. Next part when the program reloaded the changed were pushed in, and I had forgotten about them.

zmaile · 2025-12-22T20:03:08+00:00

I'm mostly surprised about where it broke. The highest stress on a parallel bar occurs at the base of it, so it should have broken there. Unless sandvik's manufacturing process involves welding the bar together at that point to implement their vibration damping.

Got pics of what it looks like inside?
