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'll be keeping this one in my toolbox of "out of the box" solutions.

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.
