Could someone help me to write a program relation in assembly mode to automate the parts in assembly. What I'm trying to do is to prompt me to enter parts location, regenerate, and see the assembly got re-assembled using the prompted dimension.
I'm doing motion study of an assembly.
Thanks

I'm very interested in getting some trainings (hands-on) in industrial vibration application, specifically in the electronic packaging area.
Any idea where to go..seminars...open course, etc.
Thanks

I need to get rid of noise "ringing" on aluminum casting from outside vibration at 2kHz. I could do this 2 ways, raise the natural frequency of the casting above 2 kHz (adding mass, stiffening ribs, etc) or place isolation material like rubber/foam sheet inside the casting to absorb the energy...
I just got old and used (almost antique) micrometers and depth gage. It's pretty dirty and lot of particle/burr deposit in the reading scale. I'd like to take them apart and clean them inside and out before I calibrate them. What type of solution should I use?. MEK?..Acetone?? Any special...
I'm doing frequency analysis on COSMOS and resulted in negative natural frequency. It ranges from -3400 Hz to 2700 hz in 13 modes. Something isn't right, but I'm not sure why.
any ideas?

What is the cheapest and fastest way to find out if my coated surface is flat. The plate is coated all around, so I can't use one side for reference.

Guys,
I'm trying to make a gasket that has adhesive on both sides. The vendor is is telling me that it is almost impossible to do that. Was it?
Thanks

Guys,
I'm a little low confused on the basic here. I need help.
I'm doing a bubble immersion test here, just for fun. The inlet air hose has pressure gage in it. I filled the enclosure with 30 psi of air ( reading from the gage) and I saw air bubble from the seam of my enclosure. Can I say...
What application paramenters would the surface mounting gasket be used on?
I seems like I always like o-ring groove type of seal, rather than gasket surface mount type.
What would the surface mounted gasket be more beneficial than having o-ring groove type seal.

My application is a rubber gasket, aluminum plate, and plastic flange. These are my component on my gasket joint. My problem is after 24 hours of installation (not even subjective to any elements) I have to re-torque it. It was rounghly 1 in-lbf loss of torque.
Once it is subjected to the...
In the practical/industrial world experiences, what would be an engineer's learning curve looks like. At what stage does an engineer stop/start to slow down learning process. I know that this is very subjective to the engineer/s goal, character, etc.
For those of you who has tons of...
What is the "K" value ( friction factor) on thread forming screw on plastic woule be. This K is for Torque = K X nominal diameter of screw X clamping force.
I would imagine that it would be higher than 1.
Anyone?

I just started a new job here and one of my goals is to be proffesional in all aspect, whether it is design task, communication, attitude, etc. can you guys shed some light on this.

How do you calculate minimum seating stress on a die-cut gasket between 2 flanges. Gasket material is Nitrile 60 durometer. I don't know the "K" (spring constant value) of the rubber. Can I calculate the seating stress based on the compression set data.
Thanks

I have a molded plastic part nut, piece of aluminum stamped part, a gasket, and thread forming screws. This seems to be pretty straigth forward stuff. I need to figure out what clamping force is needed to seal up the joint. This clamping force needed to withstand various vibration effect, etc. I...
I need to know what the clearance hole size is for screws that is arranged in 3 by 3 matrix. Is there something like this on machinery handbook?
thanks
