    I can'r believe I'm procrastinating this much but I modeled both modes in Solidworks. Here are some videos for your edutainment:
    The smaller circle translating around the fixed large circle and...

    When I was in around grade 11 in the late 80's, we were at a party that got out of hand and had to be shut down by a whole lot of cops. This was a reasonably common occurrence and my friends and I...

    This was a fun thread to read for us in the engineering peanut gallery here. Thanks for that very interesting example SeymourDumour. I guess you could sort of call that a reverse turnbuckle where the...

    If I were doing this I'd go 16Ga. We built a fluidized bed coater tank of no dissimilar dimensions and it's plenty rigid. You might be able to get away with thinner sheet but it's probably trickier...

    A good waterjet cut should be fine for holes of that size.

    +1 on waterjet rather than laser for minimizing stress. We once made 100mm wide "combs" with eight tines going down around 15mm where the other side of the comb was flat. Laser cutting made the 16Ga...

    The uPirnt is good when you are printing complete human skulls from CT data, so you need full support material and it takes like 40 hours and you need to to not fail halfway through

    I think you can ask more technical CAD questions, not in the first interview asking them to draw something but if they know say Solidworks, ask how they would approach a couple of different objects...

    I don't know if this is possible with Stratasys printers. We have not found a way to do it with the uPrint. We've done it with PLA on low cost printers and then dissolved with limonine. This is not...

    I know these people personally and the OP is selling himself considerably short. The trained CNC guy they have there is super good, and in fact trained me how to use our then TM-2 a decade ago to the...

    The reason that aluminum has become more popular than steel for suspension frames is precisely because it's easier to form complex pieces for linkages and suspension pickup points, including...

    You might modify @drcoelho's point that it wasn't possible in a small shop 20 years ago but it was certainly possible if you were Lockheed. But the fact that these advanced CAD and CAM capabilities...

    Thanks, we'll fool around with the order of operations. The configuration is correct insofar as the five axis Machine Def and Post work perfectly, so we're pretty sure the requested move is within...

    DWO Out of Range Error

    We are working to get a forth axis mode working on our new style TRT-160 (on a VM-3), where we rotate the B-axis to 90 so the C-axis rotates around the X-direction, and then it's like a regular...

    I had some correspondence with Dan Gelbart about waterjet lasers recently and he confirmed my suspicion that while it is crazy cool, it may a bit of a solution looking for a problem. The telltale...

    This is a very important point and I'd say this slowly creeping revolution, if you will, has been an important feature of machining for some time. My sense, from spending years in academic R&D labs...

    Some good suggestions here. I like the no-abrasive trick. We have a little cone device that slides onto the nozzle and clamps with a thumb screw and has a diameter of about 1/2". You can drop this...

    I think there some trick here about having the linear guides separate from the pivots, but getting the pivots to operate after a certain amount of extension. The other complex bit is locking the rack...

    The key feature is how it telescopes out from the linear guide which holds it until the very limit of extension, where it can pivot down and it evidently does this without excessive torque on the...

    You're quite right and as a customer of shops for prototyping I'd say it's actually the opposite. If you find a place than can turn your porotype jobs around quickly you try to keep it on the DL so...
