    NX 4.0 - Edit Curve Parameters

    I am trying to do the simple task of editing the parameters of a curve. When I click on the icon, then the curve, the dialogue box for the curve parameters does not appear. In the upper left hand corner it says to input diameter but there is nowhere to enter it. Is this a glitch in my software...

    UHMW vs. Delrin

    The fixture itself is made of steel. This part of the fixture only supports the flange. Metal is not an option because the flange support has to be lifted up into its locked position by one person. Given the dimensions, this would be way too heavy.

    UHMW vs. Delrin

    Mint.. Thank you for your insight into the properties of these materials. I have narrowed down the choices to UHMW and Delrin because they have low friction coefficients (so that it can slide up and down a guide), and was also told that they have good moisture resistance.. which seems to be the...

    UHMW vs. Delrin

    I am currently designing a mill fixture. The application of the component that I'm making this particular material selection for will be to hold the flange of a part during a drill operation. It slides up to the flange after the part is loaded onto the fixture, and is then held into place by...

    Cylindrical Datum Plane?

    That's exactly what I was trying to do. Thanks for your help John!

    Cylindrical Datum Plane?

    ewh... I am familiar with the process of creating solids to use as subtraction tools. I actually ended up doing it this way. But there have been other situations where having a conical plane to cut with would have been really handy. John.. Unfortunately, I cannot post a screenshot for security...

    Cylindrical Datum Plane?

    I'm trying to cut out part of a block using the angled surface of cone-shaped part. Since I need to cut off ALL material past a certain surface, a simple subtraction won't work as it would only create a channel in the block. One way of going about this, I was thinking, would be by establishing a...

    Fail Safe Pin Shear

    Thank you for the questions rb. I have come up with a number that seems to be independent of whether or not it is cantilevered at the end. sigma = M*c/I ==> F(x=L/2) = sigmamax*I*(L/2)/c = 2,509 lb I am a little concerned that the boundary conditions are not coming into play here as my...

    Fail Safe Pin Shear

    Hydro, This was not my design. I was simply asked to analyze the properties of the pre-existing design.

    Fail Safe Pin Shear

    Hey Guys, Attached is a sketch of the problem. It can be assumed that the load is applied at the midpoint of the pin. Dhengr... the sketch should answer the majority of your questions. The only thing holding the pin on the shear plane is a pnuematic mechanism that pushes the pin into place...

    Fail Safe Pin Shear

    I am a recent graduate that has been assigned with the task of determining the maximum vertical force a fail safe pin can hold. At the point of failure, the load will be fixed directly down the center of the pin. The pin is supported on either side by circular guides. Correct me if I'm wrong...

    Dry Ice Storage Material

    I'm currently designing a box that an aerospace component will be placed in during transport. It must be kept chilled after a stress relieving heat treat process, so it will be submersed in a dry ice bath. My question is.. what material should I use? After doing a little research online, I have...
