Is it acceptable to apply a position tolerance to a basic feature?
The form (and orientation) is already controlled by the profile tolerance, however I need to hold tighter control on certain parts of a the profile as they approach LMC.
Something like the image below, using position of the...
Hi,
I have a question with regards to clarifying intent using <CF> when there are multiple surfaces of the same size.
I've marked up what I want to say, and was looking for help on what would be the best (clearest, least ambiguous, lowest chance for misinterpretation) way to specify this...
Hello,
I'm having trouble specifying non-destructive examination for inspecting castings (which are used to manufacture high-pressure hydraulic cylinders) prior to machining.
I have a casting that has four cylinders machined into it - cylinder is about 2" in diameter by 4.5" deep, and each...
So I have this blind hole which runs into another through hole.
We are doing root-cause analysis on why a drill went too deep (into the back side of part, almost through) and it wasn't caught.
I observed there was nothing in the inspection plan that required any verification of the depth of...
Is there an acceptable practice to control runout (axial location) of a feature-set separately from the form of the feature-set (which is controlled on another print)?
On this print, essentially, what I want to convey is:
THE FORM OF ALL FEATURES FROM POINT X TO POINT Y IS CONTROLLED BY...
I'm running myself in circles trying to solve my own problem. Looking for some smarter minds than mind to slap me straight.
I have a nut made of stainless steel.
I have a bolt made of alloy steel which has been completely coated in a CVD coating which has a .05 CoF.
If I apply...
I'm trying to calculate K factor, following the guidelines of the Machinery's handbook (I have 29th edition paper copy, and 27th edition electronic copy) but I'm not real confident in the results I'm getting.
The machinery's handbook lists the CoF for stainless steel/stainless steel as .14 - so...
I'm trying to run a non-linear dynamic study.
I've tried to run it a few times now, playing with solver settings, but am having no luck getting past this error.
I'm not sure how to interpret this error message:
This message regarding "ETAN" seems to indicate some problem with the solver...
Hi,
I'm looking for some general advice/guidance on heating a couple pre-heat-treated materials.
I have an assembly I'm building using 6061-T6 aluminum and Q&T 4340 (750°F temper) steel.
Both parts are machined with holes, and I need to heat both parts up so that I can drop in some carbide...
How does one go about calculating the preload and pull-out strength for a buttress threaded connection?
In case it's unclear, this is a mechanical non-sealing (ANSI, not API) buttress thread. The intended application is attachment of a hydraulic cylinder to a base for a hydraulic press.
I'm...
When defining an S-S curve for FEA, do you use traditional .2% offset for yield, or do you go by the first point at which the curve begins to deviate from linearity?
Not sure if all FEA software is the same, but the software I'm using (Solidworks Simulation Premium) tells me the first point in...
The quick:
I've come up with a handful of possible options for how to structure the DRFs and FCFs for this part. I've narrowed it down to the two shown below, but I don't know which is better, or if there is maybe another way of doing this I'm overlooking. I believe both are compliant to...
I'm posting here because I wanted some input on the use of a compound datum in this scenario as I couldn't find any examples showing this setup in Y14.5-2009
I've been working with our casting supplier to establish an inspection method for checking position of some ID features to their OD...
Hi, I'm having trouble modeling this spring.
I can get the desired profile curve, but I cannot get it to complete the sweep - either as a surface or a solid. I need a solid as the end product, but I'm open in how to get there.
Any help would be appreciated, I've attached the file below...
Hi,
I'm looking for someone to take a look at the tolerance I've proposed and tell me if this is the best way to achieve the control I need, described below.
This part is made in a lathe as a side A/B process, and as such there is a mismatch that can occur where the tool path exit and...
Hello all, I have an interesting question on using GD&T to control parallelism between 2 theoretical planes.
In the example attached, I'd like to use a parallelism control frame to say "DATUM E MUST BE PARALLEL TO DATUM D WITHIN .01 INCHES."
As of now, I'll probably add this as a note like I...
Hi,
I've had problems with modeling screws that follow a tapered profile in the past. Usually I can work around this in a variety of ways, but this time, I'm really not sure how to proceed.
If I make my profile sketch big enough to cut away at the tapered portion, it becomes self intersecting...
Hi, I am trying to mate to radiused surfaces (both parts the radius was created using fillet feature) and I cannot figure out how to make this mate happen. (see attached image)
I tried using planes at a 45 degree angle to each radius, but this resulted in an error saying the planes were .0083...
Hi,
I'm having and issue where my sweep is going the opposite direction of what I want. The sweep starts at the end point of my helix. Its a tapered helix. Cutting profile is located at the bottom (larger) diameter portion of helix. Helix is about 1 revolution. I cannot change the location...
Hi. I've been asked to provide some reference dimensions for our machine operators for x,y,z locations of certain features. For this to work, I need to be able to use clipped (linear) dimensions in some cases, which doesn't seem to work in solidworks.
I'm wondering if there is any way to do...
