We have some custom stainless steel tools with hole saw type geometry where the cutting 'tips' are not of a standard geometry--it has a scalloped leading edge which creates two sharp 'peaks' at the innermost and outermost edges:
These items are intended for limited re-use, but we would like...
So, we have some machined parts of somewhat dubious history where the drawings indicate the parts are 316L but due to the fact one of the components exhibited ferromagnetism and was not galling in a same-material pair, we suspected the material may actually be hardened 400 series (e.g. 416/420)...
This is less of a Solidworks question and more of a general solid modelling question. If you have a model with a known but irregularly shaped volume, are there any utilities that can create a best fit volume packing of another known shape? Preferably with some other constraints such as "always...
Should be easy to search for this but I guess I'm using the wrong terms.
I have a file open from PDM that I did not check out when opening (i.e. "Read-only"); I made some changes that I'd like to save without having to save as a new file. Is there a way to check it out now that I already have...
I think this is a dumb question but I may be the dumb one so I figured I would ask it here and get a more authoritative answer:
Does the loop end condition in an extension spring contribute at all to the spring load expected when deflected? i.e. would it definitively indicate a different...
I didn't create these templates I'm trying to use but I can't explain this behavior either.
The drawing sheet is linked to $PRPSHEET:"ITEM NUMBER" but it appears to be pulling information from somewhere I do not know (I don't know how to change whatever that value is either, apparently).
I...
A coworker may have inherited this generic set of drawing notes (attached) but this one is dubious to me.
Per note 6 the entire part has a generic surface profile requirement of 0.8 mm (this changes between parts, but the note is ubiquitous). This is relatively generous in my opinion, but...
Chemical requirements of UNS17400 per ASTM A693 changed such that previously (rev -13) a limit of Ta+Nb of 0.15-0.45 was the acceptable amount. In the newest revision (-16) they have removed tantalum entirely and list only Niobium 0.15-0.45. In a theoretical context of Ta=0.00... these two are...
I have the dubious honor of trying to assess the impact to several of our technical standards which turned into pandora's box. Turns out we have three vendors annealing using three different sets of parameters. As we are generally satisfied with the product(s) I see no reason to upset the apple...
At my last company ~5 years ago we specified most if not all of our stainless instrument materials "per ASTM F899" as that is a blanket specification that includes such specifications as A276, A484 et. al. As far as I am aware, the chemical requirements of F899 are identical to those of the...
I have a screwdriver tip that consists of a .117 (3mm) hex with a .063 diameter hole located thru the axis of the driver. Because these are used in a clinical setting our material choices are limited by patient contact (biocompatibility) and corrosion resistance as they are put through repeated...
Not sure if Metallurgy or this forum would have the best resource but here goes:
I’m not an expert so please correct any inconsistencies I have in my theory.
I have a few questions regarding the effect of titanium nitriding and/or aluminum titanium nitriding that I'll refer to as their...
This is a simple question that I'm embarrassed I can't find an answer for. Given a simple hole in a part where I'm interested in more tightly controlling deviation in the 'x' direction than the 'y' direction can I simply do a single segment position tolerance where the first segment one...
I'm modeling a heat sealed package that would preferably be slightly associative to the contents of the package. (Something like this: http://i55.tinypic.com/2gsj37l.jpg )
This is more for a cosmetic representation so accuracy is not particularly important but having it pseudo-parametric (e.g...
I'm trying to model a ball end torx and I can't seem to find a good picture or a reference for what it looks like. I have a hard time visualizing what it must look like.
Modeling it is a whole other challenge.
Does anyone have any sources or suggestions?
Thanks.
I've searched but with little help on how a weld is interpreted on cylinders when they abut another cylinder and the view is perpendicular to axis (see attached).
Of the three examples shown I can't see how any mean anything different (all are all-around anyway) though the 3rd seems redundant...
I've used SW for several years but up until recently I was on an older version (06/07) that permitted you to double-click the reference and select the new one.
I've changed references in SW2009 both by "breaking" the link (changing file name) which lets you find the new one but that's not...
I'm nigh certain this was answered before but I didn't find it in a brief search.
I have an assembly with multiple components and I want to assign material properties (more specifically densities) so that I can estimate the mass of the whole part. Previously I've assigned different colors to...
I have a snap fit concept that is fixed at both ends(deflects in the center) and I have very few options for changing the cross section or amount it needs to deflect. However, I would like to minimize the length necessary to deflect my prescribed amount without failing (FOS approximately 1)...
I'm working on a device where two PEEK surfaces are moved relative to each other in discrete fashion under load. In this situation overcoming the static frictional force is a concern as it is manually actuated. This motion is one time only for assembly so wear is not a significant concern.
I've...
