    Bonding TPU to PVC

    I don't know how the rules apply to this, but my company has a couple adhesives that might fit the bill. I want to help, but I don't want to violate any rules.

    It absolutely is a degree symbol, and I now see why that doesn't make much sense. Thank you Andrew!

    Okay, here's what I came up with. I have some redundant dimensions and datum references on there because it seemed like it would provide more clarity to whoever would be making the part.https://files.engineering.com/getfile.aspx?folder=ae3a9524-1008-4f97-a789-ebac2cbea72e&file=test_fixture.pdf

    Okay, I think I understand more now how this all works. It's more simple than I initially thought. Thinking through 3DDave's process, how features relate to each other, how the part is fixtured, machined, and gaged, helped me a lot. pylfrm, So the mating part is just a small test disc like...

    Okay, here's what I've got so far. I know the hole callouts should not be in boxes, but I haven't figured out a clean way to do that in solid edge yet. Still not sure what should and should not be a basic dimension, but I'm basing my understand of the concept on figure 3-29 in ASME Y14.5-2009...

    Pylfrm, Okay, I think I understand. A few more questions... I will add a view that contains the axes of the three holes and dimension said holes in that plane. Is there an accepted way to identify that view, or should I just indicate datums in the view and write a description? For the hole...

    Here is a picture of the actual part, but I'm changing it so it's made from 1" square bar stock instead of 2" and removing the relief hole.

    Continuing this from the other thread so as not to hijack. Here is what I have so far, after making some adjustments based on advice already received. Thanks to all in advance.

    Please have a look at my application of GD & T

    Okay, I'll start a new thread.

    Please have a look at my application of GD & T

    Thank you! I really wasn't sure if I should make it an oval or if that would be confusing. Should I do the math and make a literal projection of the round hole at 45deg? I only have access to 2D. I understand that referencing D|C| would constrain the hole's position with reference to those...

    Please have a look at my application of GD & T

    Immediately noticed a mistake on the right view. I meant to reference C and D in the frame, not A and D

    Please have a look at my application of GD & T

    Hello all, I just wanted to piggyback off this post. I was never taught GD&T in school and now I'm working on some drawings that will be submitted to a big deal auto manufacturer. I'm trying to wrap my head around it and I think I'm getting the idea bit by bit. I'd really appreciate if someone...

    Highly Viscous Non-Newtonian Pipe Flow to Dispensing Nozzle Calculations

    Edstainless/bimr: It is an intermittent flow, and that makes me think of it a little differently. Realistically the pump will go through a drum or two of the material just to fill and pressurize the pipeline and establish an air-free dispense. Then it will be "bled off" in 60cc or so increments...

    Highly Viscous Non-Newtonian Pipe Flow to Dispensing Nozzle Calculations

    Latexman, the ID of the hose will be 3/8 inch.

    Highly Viscous Non-Newtonian Pipe Flow to Dispensing Nozzle Calculations

    LittleInch: Thank you very much for your input. I would love to get some more testing done, but we don't have a lot of capability for such things in house. We supply the dispensed material primarily and the dispensing equipment secondarily. Piping and such isn't something we sell or integrate...

    Highly Viscous Non-Newtonian Pipe Flow to Dispensing Nozzle Calculations

    Here is the relevant viscosity data if it helps:

    Highly Viscous Non-Newtonian Pipe Flow to Dispensing Nozzle Calculations

    LittleInch: your interpretation is pretty much spot on. To clarify: Viscosity is variable as it is a shear-thinning fluid. Power law fluid constants n = 0.027 and K = 5157 fit the available shear rate vs viscosity data well 14 gauge = 1.6mm inner diameter

    Latexman: of course, my apologies. Attached is an illustration that should help matters.

    Highly Viscous Non-Newtonian Pipe Flow to Dispensing Nozzle Calculations

    Hello everyone, I'm working on a problem in which I am trying to recommend a hard pipe diameter to a customer for a (relatively) high viscosity non-newtonian fluid. I am treating it as a power law fluid and have obtained constants K and n to describe the viscosity in relation to shear rate. I...
