Multi-axis CNC machining is my porn...and I'm not ashamed to admit it.

The programming of the workpiece rotation and the speeds and feeds are amazing. Seriously wonder about the inserts and how some are lubed and others are cut dry. If anyone has input, I'm eager for the education.

Most carbide tools and ceramic/carbide inserts are designed and built to handle the workload without lubrication. They can handle the higher heat and usually are much sharper than the workpiece being machined. They also hold an edge much longer than HSS (High Speed Steel), the other major metalworking tool material. For operations like turning and milling, coolant isn't needed, but for drilling or deep cavity machining, flood-type coolant is needed to keep the chips clear of the workpiece (which are much harder than the workpiece and affect tool life significantly if they are "recut").
HSS usually requires coolant so that it can maintain its edge, its coating (most HSS tools have a carbide or ceramic coating to boost tool life), and clear chips. Aluminum also galls very easily and can weld itself to the tool. Coolant is usually used for aluminum to avoid that, for carbide and HSS tools.
In the video, all of the drilling operations used coolant, and I'm assuming any other operations that used coolant were using HSS tools.

very nice. I used dry for engine block surfacing and boring applications, but the coolant for bored holes makes a lot of sense.

It just comes down to the application and tools involved. The same way that flat-head screwdrivers become chisels/punches and pliers/vicegrips become hammers in a pinch. ;)

I'm still in the "what-the-actual-fuck" stage. This shit be crazy...

witnessing the tool paths is a fun puzzle. I can't tap a hole to save my life, so that's always interesting to see it don't on a mathematical feed rate. Hell, can barely spell interpolation...

Don't ask how many times I had to spellcheck ceramic from "cemaric" in my post above....it was embarrassing.

good stuff. again, just amazed at the competency needed to have the tool offsets correct etc. Their brains are different than mine I guess. For OPPO's that wonder how manufacturer's give us cars; take a bit of time comprehending the math needed to make a single component. Then think about the effort needed to generate a new generation of car every 3 years. Cars are cheap.
