    7075 plate has been unstable for quite some time. Earlier this year, the pricing was stable but the lead time was something stupid, like 4-5 months.

    I think it's been on the website for about a month.

    I was talking to somebody about ROI calculations for a new shop, and mentioned that the TL-1 I got back in 2012 was sold in 2015 for 97 cents...

    In order to succeed at lights out during the night, one should run lights out during the day. It's a culture that should be embedded at all levels of the company, starting with the programming.

    For now, if you install the center jaw the same way every time, e.g. use one hand to pull the jaw toward you, and use your other hand to tighten the screws, left screw first, then the right, then...

    We had some major supply issues and ended up discontinuing the aluminum master jaws. Couldn't deal with an open-ended, 5-month estimated lead time quoted back in January for 7000 series plate in the...

    How much time is spent loosening/clamping vs. cleaning chips in preparation for the next loading? Fixture design should take chip management into account. Hydraulic and pneumatic fixturing introduce...

    Sure, but most of the time we're talking two independent robots. Here I'm referring to two arms connected to one controller, thus no syncing/runaway issues. As far as the controller is concerned, 12...

    The programming on the UR robots is excellent.

    That said, the original Baxter had two arms. I'd like to see a 2-arm UR connected to the same control box. I'm not all that interested in syncing...

    Keep slowing it down.

    Rigidity decreases exponentially with length (to the 3rd power). So an 8" toolholder deflects roughly 8X as much as a 4" holder.

    In the future, try to find tapered...

    Modify a 5/8" OD drill bushing. They're available in stainless steel if you don't want to deal with machining hardened steel.

    The OD tolerance is typically +.0014 to +0.0017, so they're going to...

    Most horizontals are pallet oriented. By design, these machines sacrifice work envelope for pallet changing flexibility. They're designed for smaller parts.

    You can find them under the "Fixturing" or the "4/5-axis Vises" tabs.

    Work in progress, so a lot more stuff will be added regularly.

    I think the answer is that there's no good answer. You will rack your brain trying to figure this one out. Aside from calculating net present value, fixed storage costs, etc, there are so many other...

    Since single point diamonds are periodically rotated, they're self-sharpening. So you replace them when they get too small, which often takes years.
