    Bill of Material of an assembly with Material definition

    I already have the material assigned to each part, but that is a parameter that does not get shown in the BOM analysis.

    Bill of Material of an assembly with Material definition

    Is it possible to view the materials assigned to all parts in an assembly?

    Assembly Constraints blown away

    I have a simple rigid assembly which is constrained and fine. Then one of the sub-assembly objects gets modified, perhaps a chamfer is added on a surface. Then in the top level assembly, whatever constraint was back to that surface gets blown away, it appears the reference name changes when...

    Company with multiple CAGE codes

    I agree with a company like Parker, where each site has a defined product line. My particular case was in regards to a Smalley or 3M, where they ship the same product from different sites and the Cage code results from BINCS do not give any indication as differentiation between them. Sometimes...

    Company with multiple CAGE codes

    When calling out a vendors item in our bill of materials, or on a vendor item drawing, we use CAGE code and their part number. What happens when you look up a company and more than one CAGE code is shown. Does it matter since all you are doing is identifying the company? Thank you

    CATIA V5 and using VB6

    So basically, you are using VB6 to run CATIA if it is not running like any other program (I've used VB6 to run Word and Excel and Access before) and then controlling it with VB instead of CATIA controlling VBA. Sounds good, thanks for the clear post with code. Code always helps!

    CATIA V5 and using VB6

    Can anyone tell me if you can use VB6 within CATIA V5? Natively it uses VBA which does not appear to use PropertyBag's. If you can use VB6 within CATIA V5 then how do you do this? Thanks

    Pressure Drop through orifices in a rotating disk

    I have two volumes separated by a rotating disk spinning at ~8000 rpm with five 0.125" dia (0.200" long) holes in it. They are machined in the disc at a diameter of 1.2". I know how to calculate flow with a certain pressure drop through these orifices if they were static, but how do I account...

    Pressure Distribution with a spinning cylinder in stagnant volume

    Thank you btrueblood for your posting, very helpful.

    Pressure Distribution with a spinning cylinder in stagnant volume

    I have a high speed (30-40,000rpm) 1 inch diameter spinning shaft in a relatively otherwise stagnant volume. I need to know the pressure of the fluid at different distances from the OD of the shaft outwards. I have searched and can only find information about a spinning cylinder in an airflow...

    Ball Bearings running in Aviation Fuels

    Speed = 5000 rpm Radial Load = 175 lb Required bearing bore size = 12mm Fluid Viscosity = <1 cs (by the way, if user AHRBearing is anything to do with http://www.ahrinternational.com/, I couldn't get to any pages on the website other than the main page)

    Ball Bearings running in Aviation Fuels

    Does anyone have any experience with derating ball bearing life for running with aircraft Jet A type fuels as the only source of lubrication (flooded)? Thanks

    Epoxy bond surface finish parameters

    I am looking to increase the bond strength in a current application. Are there particular surface finish parameters that best define surfaces for good bonding? (we currently look only at a minimum Ra). We are using quartz as the blast media. Are there general guidelines for size/shape of the...

    Torque Motor Calibration

    Thanks for the suggestions Philrock. Am I right in saying there should technically be almost zero difference between the torque pulling the weight going up and down at a constant speed? Thanks

    Torque Motor Calibration

    We have setup a dynamic calibration of a torque motor and system. One end of the torque motor has a constant 3 rpm input from an air motor through a gearbox. The other end has a copper wire attached to a 12 lb weight. We record the torque as we raise and lower the weight at a constant speed...

    Tolerance stack-up for multiple components to find interference risk

    To make a short story long, an error was made on some original parts where the print tolerances and runouts easily allow inteference, which I do not want to happen. The print has now been corrected for future components. But what the components have been machined too is much tighter than the...

    Tolerance stack-up for multiple components to find interference risk

    BillPSU, Thank you for responding. I guess I am having a hard time determining what is interfering. For size and runout of one of the two parts, can I just take the mean size and add the mean runout, and add the size 1-sigma and runout 1-sigma together to get a normal distribution curve? Then...

    Tolerance stack-up for multiple components to find interference risk

    I have two components (diameter feature) with a size and a runout tolerance defined on the prints for both features. I also have actual measured data for these features too. My original hope was for these features to run in clearance 100% of the time. Since the 3 sigma actual measured...
