Hi,
I'm milling a part out of flat plate with a single 2D wall profile. I have multiple parts in one program to be cut from a single sheet, so I have one Wall Profile operation per part - internal geometry and the outside profile. I've placed start points in each hole and for the outside...
I am working on a design for a die cast aluminum part, alloy EN AC-Al Si9Cu3(Fe) in as-cast condition. I am wondering what stress level to use as a limit for fatigue failure. I have read that because the material is so brittle that it is acceptable to just use the ultimate tensile strength of...
We are resistance welding oxygen-free copper wire braid and it's changing colors to purple/red. We haven't seen this before but the supplier is trying to improve the strength of the weld and I think has increased time and/or temperature in their process. Does this oxidation have any negative...
I am searching for a current measurement clamp that can be used in a cold chamber at -30°C. The one we currently have can only be used to 0°C. Any suggestions? It needs to connect to a data acquisition unit; I'm not looking for a hand held meter. Thanks!
I've looked through DigiKey and Mouser and can't find this. I just picked up a BMW 135i with a rusted out convertible drive motor. It's 2" in diameter x 3.3" long with a .246" shaft with a single "D" for the connection to the pump. It has tapped holes in the face for the adapter that bolts it to...
I have an assembly that needs to be vibration tested, consisting of small plastic parts clipped into a stamped steel ring. I need to glue the parts together to prevent relative motion during the test. The plastic parts are made from Vyncolit X 689. "VYNCOLIT X689 is a Glass beads & short fiber...
I have an application where a braided copper cable is breaking during a sinusoidal sweep vibration test, at the termination points. Changing the temper of the wire is the easiest option to improve this condition. Redesigning the parts to move the resonant frequency is not an option right now. My...
