Is there any relationship of fatigue crack growth to material grain direction?
In the case of heat treatment / work hardening, how would it affect the material properties in terms of fatigue?
Hi,
I have a scenario here whereby I have a sphere of dia .1875 being compressed by two metal plates (Parallel to each other and tangent to the circular surface).
How do I calculate the amount of deformation on the sphere for a given force, say about 10lbs. (Assuming that the plates are...
Hi Tmoose,
There's two reasons I need to avoid slippage.
1. Minimize wear on surfaces.
2. I need the bearings to lift a retainer (.1 lb max) up at constant speed.
I have precise machining on the bores and rods (.00001" bilateral), so that's not an issue. There would not be any grooves as the...
I'm involved in a project whereby I'm trying to determine appropriate ball bearings for my design. Here's how it works:
The bearings are spaced evenly in a radial manner and are "squeezed" between a tube ID and a rod OD. The bearings preload establish good contact and prevent slipping while the...
Timelord, you are lucky.
I was using UG for a long time till I converted to Pro/E and was asked to pick it as I went along.
UG -> Pro/E is complete pain as UG emphasize a lot of 2-D and 3-D curves (not so parametric) rather than sketches. And it employs a lot of primitives.
SWX -> Pro/E is not...
I managed to do it another way by adding notes and putting in the link to the model, for instance... keying in "Hole Depth@Sketch4@@Default@TBD Isolator.SLDPRT"
It reflects the dimensions in the drawing but not the tolerances. Still working a way around.
Apparently it doesn't allow it. The only way I thought of is to create a note and linking it to a created dimension. Then delete the source. However this does not work for the tolerances as it's taking values from <dim> in the source.
I have been working with UG and Pro/E in the past and they...
Well, I want 2 driven dimensions displayed in an annotation that shows the diameter w/tol and depth w/tol.
I know that insert model items will work but it shows two dimensions completely.
In another scenario, I have a rectangular cutout with a depth callout but I can't display the dimensions...
In this way the dimensions will not be updated / driven by the model updates.
In addition, I would like to make my bilateral tolerances in a top bottom display. Can this be done?
I have two dimensions, one describing the hole diameter (with tolerances) and the other describing it's depth (with tolerances). How do I display them in the drawing?
