    Creo 1.0 config files + Windchill

    Hello, Similar questions have been asked but I have yet more! We are implementing Creo 1.0 and Windchill 10. I understand the order that Creo uses to parse config.pro files and that it overwrites previously loaded choices except for config.sup ones. However, the locations are still unclear -...

    Default Tolerances

    Ok I give up - I want to change the default tolerances for my parts in Pro/E Wildfire 5 (soon to be Creo 1). I want three decimal places to go to +/- .005" I've placed the following tag in my config.pro: "linear_tol_0.000 .005" but in the corner of the screen (tolerance display enabled) it...

    Experiment for Schoolchildren Edutainment

    I think this is the best forum, but please recommend others if you can think of a better one: There is a program for National Engineers Month (February in case you forgot) that involves going to local schools and presenting on your job and engineering careers in general - drumming up excitement...

    Allowed angular slop on UNC thread?

    Kind of a weird question, but does anybody have any info on the allowable or resultant angular mis-match on a standard UNC thread? I realize the threadform standard is more concerned with diameter fits, and that my question is heavily dependent on the length of the screw - let's consider an...

    Small part machining R.004"

    Ok, I have a potential part which is pretty small, although not microscopic. I need to get a 2d shape cut with corner radii on the order of .004". I'm working in titanium with a part thickness around .050" Should I be looking into laser-cutting, waterjet, or EDM?

    Titanium Alloy strain-hardening exponent?

    Can anybody point me towards a source for the strain-hardening exponent for Titanium? Specifically Ti 6Al 4V ELI, annealed. I've seen people give numbers around n=0.15, but I need an actual source to cite. Thanks in advance.

    "Type II" Titanium Anodize

    Hello all, We have several vendors who will do this process which produces a dark grey sheen and is claimed to produce smoother surfaces, better galling properties, and improved fatigue strength in titanium alloy (Ti 6Al 4V) Can anybody point me towards some non-proprietary papers that...

    Self-stopping drill depth?

    Hey all, I have a question which seems to be best-suited for this particular forum. I want to drill through a relatively soft material, and once I reach a change in material density/hardness I want the drill to stop itself at that depth. I don't expect a screeching halt, but a general stoppage...

    Cross Section Analysis in Assembly

    Ok, in a .ipt file, you can perform a cross-section analysis which will give you the 2D section properties of your cross-section. I'm interested in area at the moment but polar moment, moment of inertia, etc. are all there as well. Is there a way to do this to a .iam assembly? I have two...

    Part rebuild, base view crashes Inventor

    Hey all, My co-worker is having an(other) Inventor 2008 issue. He's spent the last few weeks working on some pretty complicated geometry for a medical device we're working on. After several iterations he's finally happy with the design and ready to take it into make a drawing. Upon placing...

    Deep hole drilling + ball-end fillet?

    Hey all, I have a question as to whether or not this feature is (reasonably) machinable. I have a 8mm OD tube, approximately 180mm long, and I need to step down from a 6mm internal diameter to a 3mm diameter about 10mm from the tip (6mm ID for 170mm, then 3mm ID for the rest). I know this can...

    Flexible Endoscope/Borescope Design Info

    Hi all, Does anybody have any experience with endoscopes and/or borescopes? I'm interested in the mechanism used for articulating the tip, I'd imagine you could use something similar to a push-pull control wire...not unlike a throttle cable? However, it seems there has to be a better way to...

    "Shop Class as Soulcraft"

    http://www.thenewatlantis.com/archive/13/crawford.htm Just thought it was worth a read, as we engineers always seem to walk the line between shop and desk.

    Middle Click Rotate

    Hello all, we all know that middle click rotates your model about the origin. However, I just discovered that if you middle click on an object you will get some constraints which may be handy: Middle click - select point : The point becomes the origin of rotation. Middle click - select edge ...

    Min/Max Material Models

    Hello All, I did a quick search but couldn't find anything on this, so. Is there a macro/plugin that will create new model configurations for the MMC and LMC of a model using the assigned tolerances?

    Relocation/job change value

    Hello All, I've read through this forum with interest, but now have come to think hard about that unwieldy beast I call a career. Two years ago I was just out of school (mechanical) and applying to every company I could think of. I got as far as a few phone interviews but it basically came...

    Lost in Euclidian Space.

    Assuming we're dealing with Euclidian geometry here in SWx... I have three orthogonal planes, but I can't directly put a reference point at their intersection. I have a plane and a non-planar axis, but I can't directly place a point at the intersection of the two. I'm aware there are...

    Pulling dimensions into a note

    Forgive me if this has been answered before, I couldn't find it if so. I have a dimension (from a fillet) on a part which I want to show up on a drawing. Solidworks will not pull this dimension automatically (assumably because I do not have an orthogonal view to see it). Since it's a fillet...

    Line Perpendicular to changing curve

    Hello all, this may have been asked before but I couldn't find the thread if so. I have a closed 2D contour, call it a jellybean, I want to get a line to be instantaneously perpendicular to this curve at any given point. This is a very simple task with a circular contour, but when my radius...

    The reasons for reasons.

    http://www.newyorker.com/critics/books/articles/060410crbo_books Haven't read the book, but the write-up was pretty interesting. Basically the premise is that different types of people place varying degrees of importance on different kinds of reasons. Basically, we engineering types will read...
