Ahh I get it now..... Thanks alot Weavedreamer that really helped me.

KENAT This is actually and old US government print. Thanks Weavedreamer for the illustration. I am still confused though on how you figured the length of the chamfer. Is there a formula for figuring the length off of the taper per inch. Maybe if you could just explain how you came up with...

I have a drawing that dimensions the chamfer differently than I have ever seen. Instead of a length it gives a basic dimension of .536 taper on dia per inch of length. It also gives a diameter dimension .037 basic from the end of the part. I have attached a pdf of the drawing to better show...

Perfect application for a groove pin.

Yes in the case of JsTyLz application where you are locating two housing together and you would want them to rotate about each other. You would design a pin with grooves in the section of one housing thus locking the pin in place. You would then be able to rotate the other housing on the other...

You may want to look at using a pin with a groove already on the part. The part will have an area of the pin swedged to a larger diameter giving you an interference fit in that location. This way you don't have to have a separate operation in your process for the staking. Look at this website...

I am looking to find the amount of compression that a spacer made out of 1074 strip steel can withstand. Basically it is used in a plastic housing to protect the plastic from crushing when a bolt is tightend down. In this particular case the spacer would be about .295 diameter with a wall...

The processing before the Black Oxide can cause Hydrogen Embrittlement. Acid is used to clean/Etch the parts prior to processing.

I'm trying to determine what the double shear value is for this diameter 416 ss with a RC 40 heat treat. The part will be used as a shear pin. Thanks

Thank You for the reply.

Hi All, I am looking to find a "ballpark" calculation of converting tensile strength on heat treated material into a shear strength measurement. I would then test the forumla when I get the parts back. Specifically I am looking at 1/4 diameter Pin 416 SS heat treated to Rc40. I would be...

Each company will seem to have different titles for the same job. Titles are basically as good as the paper they are written on. Its what the substance is behind the title that I focus on.

Medicine Engineer you seem to be avoiding the question of where you live now. I don't think it is too hard of a question to answer. Prohammy has answered most of your questions very openly and honestly. Why are you afraid to say where you are from?

Have you looked at Grooved Keys Check them out here http://www.driv-lok.com/grv_machine_key.htm

We use Edgecam and for the most part is has been a great tool. We can open Inventor dwgs straight into Edgecam and this has helped. I have had no issues with support, but a lot of that has to do with your VAR and I have had good results with mine.
