    A use for Large Metal Additive Mfr with Weld Wire?

    I've been researching more and more about Wire Arc Additive Manufacturing technology. The state of things seems to be pretty respectable, but not widely adopted as far as I can tell. The technical aspects all make sense. The final material quality, with good weld procedures, wire, and...

    Industrial-level FDM Machines

    I almost posted this in @arunmo's thread: http://www.eng-tips.com/viewthread.cfm?qid=422604 but it would've been a derailment from the original post, so I'm starting a new thread out of respect. I was looking specifically at Titan3dRobotics. I'd like to know if anyone has any input on the...

    Difficulty applying datum simulation of two coaxial features - cone and cylinder

    Referencing ASME Y14.5-2009 I'm looking at section 4.12.2 and referencing Figures 4-25 and 4-26. I have a question regarding the best/proper practice in holding or simulating datums on a part, to inspect total runout. The situation I'm faced with is a single datum axis simulated by two coaxial...

    Help: Export assembly PRT to STP or Parasolid, import with new names.

    Here's what I am trying to accomplish: I'm using NX8.0.3.4 Customer sends us a NX model. It's an assembly of components. What I need to do is create a copy of that model with completely new names in order to modify the model and create drawings as needed. The new names must comply with our...

    Learning resources for CATIA V5

    Greetings, Where I work, we primarily work with NX for design, drafting, & CNC programming. We also have a seat of CATIA, for using some customers' data. I'm unsure the extent of modules, but I assume it's minimal. It is not just the ENOVIA viewer, we have a few seats of that elsewhere...

    Resources for Creative workholding and fixturing in CNC Machining

    I sometimes feel like I might be stuck "in a box"-way of thinking when it comes to fixturing and workholding. So far, it's been mostly just experience, a bit of collaboration and networking, and trial-and-error. But I fear the dreaded "echo chamber" effect of not getting new/fresh ideas after a...

    NX8 : Plotting with object translucency

    Using NX8.0.3.4 I feel like I'm either missing something simple or desiring something not possible. Using "Object Display" properties to change the color and transparency/translucency of an object, I can change the color and translucency of an object which then also shows in any views on a...

    Issues with JT2Go or Other PMI model viewers

    I want to be able to provide some manufacturing personnel with a computer that can view JT files with PMI. All of our in-house work is NX. Some contracted work from customers will be NX or CATIA. We do not have CATIA, only Enovia (V5). At the /least/ we want to be able to set computers up...

    Symbol Identification Question

    I tried searching but when you don't know what to call thing thing you're searching for, it's hard to find results. This FCF is attached to a plain hole perpendicular to a flat surface, thru the entire body, with the exit surface parallel to the entry surface. Basically the hole is as simple...

    Machine programming to account for thermal expansion

    I tried to search and find previous topics, but nothing that answered my issue came up. If you know of a thread, I'd be happy to know of it. Goal: to be able to send machine programs to the machinists/machines that allow for coordinate variations to accommodate expected thermal expansion of...

    WAVE PMI Linker for multiple instances of a component

    Using native NX 8.0.3.4 No Wave Link Control module. Using "WAVE PMI Link" only, in assemblies, is it possible to link the same PMI in multiple instances in an assembly? Taking a very simple example, let's say Plate 1 is connected at 90 degrees to Plate 2 via multiple angle clips/brackets I'll...

    4140 CT / Cal Al source - large mat'l

    We have a customer requesting 4140 Calcium Aluminum treated. That's not unusual other than the part would be best suited by us receiving a 24" diameter, 5 or 5 1/4" thick plate. Having a 24x24 x 5" THK square would suffice, though would not be ideal. At this point I'll just take what I can...

    ASME Y14.5-xxxx Profile of a Surface - clarification

    I am butting heads with one of our quality department inspectors. He's our lead inspector and we disagree on the application of Profile tolerance of a Surface. I've attached a simple sketch we drew up together to argue over. He believes that a hole, slot, etc, that intersects the surface...

    Re: ASME Y14.5M-1994 - positional tolerance with no datum/reference

    I have a "best practice" question that I couldn't find specifically addressed using the 'search' function: We have a couple customers who will sometimes/often call out hole positions with a positional tolerance but not provide any datum or basic dimension. We -usually- are supplied a 3D model...

    NX8.0 Modeling within Assembly - trouble finding correct .def file

    New member here. 'Engineer' at a Precision Manufacturing Job Shop focusing on tool&die, aerospace, defense, medical, and a whole lot of stuff that are either too hard or too much of a pain for other manufacturers to handle. I'm a bit green at NX, we're using NX8.0, soon to upgrade to NX9, I...
