    One way is to have them do it. Have them measure a handful of parts using calipers, mikes, and gage pins and see how they do.

    The value of such a test is debatable. Possibly more important if you...

    You won't need tool life management for 6061. Replace tooling on a scheduled basis rather than on a timer. Use PCD where applicable. Err on the side of caution and run your coolant rich, but not too...

    There's no easily solution, so you'll have to get creative.

    Consider filling gaps, counterbores, etc in your fixture with silicone RTV wherever possible. The stuff is a pain to remove, so keep...

    The ability to plunge endmills has gotten better over the years, but it's still an inherently unstable process where the only failure mode is flute packing and instant breakage. No warnings through...

    How big's your machine?

    Our 22" vise with machinable soft jaws and Mitee Bite Versagrips will make quick work of that. One vise with wide jaws or two vises with normal jaws.

    Consider a 275 or 330 gallon IBC tote instead. Even a small drinking water RO system will fill that up in a single weekend.

    55 gallons is barely big enough for top-off when you have four machines,...

    I'd plan on pouring dedicated foundations for both those machines. Small price to pay to ensure highest level of volumetric accuracy.

    If you're on board with that, take that into consideration...

    Maybe the pace of the course is too slow. How much time are they spending coding basic 2D shapes into G1/G2/G3 toolpaths?

    In the real world, it's not about being able to write toolpaths by hand....

    No, but Desktop Metal and Markforged's Metal X both use technology similar to MIM.

    So users of those systems would probably run into the same issues as the OP.

    I think that sums it up pretty well. The next problem is always right around the corner.

    A cordless drill will do the job but it's not fool proof. Clutches can get bumped and aren't that accurate to begin with. Torque also doesn't stay consistent as the battery drains.

    It's a...

    It could hypothetically trigger the probe but I've never seen it happen. We use air blast on most probing cycles.

    Nice looking clamps!

    We chose anodized aluminum for the supplied clamps in order to bias wear towards the clamps rather than the T-slot table.

    The hardness of cast iron used in T-slot tables...

    Our Kaeser dryer died after 3-1/2 years of service. Kaeser's techs said it would cost more to repair it than buy a new one.

    We now have three of those Schulz units. They're made in Italy,...

    We have an SK15 with 2X 200 gallon tanks.

    It's too big for our load requirements: four horizontals, a vertical, a lathe, a WEDM, and various blowguns/support equipment around the shop. The...

    A short gage length (e.g. 2") CAT50 holder should have plenty of rigidity for a 1" endmill without dual contact.

    Halving the gage length from 4" to 2" should provide noticeable improvement over...

    A ribbed part flexes less under its own weight, but it's certainly not more rigid.

    Area moment of inertia decreases when material is removed no matter what.

    NLX is direct drive.

    C-axis milling gets tricky when parts get that big relative to the size of the chuck.

    There may not be a great solution other than going to a much smaller endmill, e.g....

    Probably crack propagation starting with a small internal defect, and possibly embrittlement during sintering.

    Solid titanium bars and forgings usually start from a cast billet that's vacuum...
