I've been a "professional" design/mechanical engineer for... hmmm over a decade now, it sure doesn't seem that long. I also like using my engineering skills at home. Yes, I did in fact model my deck in SolidWorks before building it, but I did show some restraint, I didn't animate the construction. I've been doing design work for about as long as I can remember and thouroughly enjoy sharing my experience and failures with folks to help them learn. In any case this looks like it should be an interesting group of folks to interface with and I'm looking forward to surfing the forums.

We are a fledgling watch company in the process of designing and producing our own brand of wristwatch. We are based in USA. We have been at this idea/design process for about 2 years now and have finally gotten to the point where we are ready to start production. It started as a part time hobby- tinkering with and modifying watches. Then we thought "hey, we could probably make one of these ourselves." So after acquiring several lathes, mills, and just recently a CNC mill and "teaching ourselves :p" how to use them we started playing with machining watch cases and various parts. Anyway, that's where we are now and we found this looking for some "technical support" and possibly some manufacturing help. We would like for our watches to be solely made in the USA (or at least as much as possible). Look forward to talking to you all. ]]> Pop in and say hello!

Ok, a bay windows is a three part window with the sides situated at a 45 degree angle from the middle and what I need to figure out is the full width of the window and what I do know is the middle with and the side witdths(but remember sides are at a 45 degree) to figure out the whole with i have to use the angle (45 degree) and the width of the angled side (let's say a 24" flanker) so I do know the angles and the hypotenuse,

If I'm not clear enough I can do an example drawing, please let me know!

And how would I do that calculation or write that formula in exel?

I wasn't good at trig, I never did pick it up so....

Anyway, ill thank anyone for thier help!!!!!

Someone with a passion for Golf would be ideal but some one willing to create something that has the potential of making millions would be better. I have been around this business for 10 years and this product would become a must have. It would become the standard for which all Golf practice is done. The few people I discussed it with agree this would be a standard in the Golf industry. It is related to the Golf Ranges Golf industry. I have thought of a few types of prototypes that might work but I need someone with better understanding of what can be done to see if it can be made at a low effective price...

I would like to make some code to draw gears.

I have a problem for drawing the involute curve of a teeth.
I finally have the function that calculates the curve but i do not find a threshold for stopping at the right time, when hitting the outside circle.

-> if angle_inc=0.1,min_angle=0,max_angle=?
point_count=(max_angle-min_angle) / angle_inc.

How could i determine the max_angle? If i can compute anything defined here: http://www.engineersedge.com/gear_formula.htm.

I guess it must be directly related to (module or diametral_pitch), the number of teeth and the angle of pressure.

I have read a lot of documentation but i lack a bit of fundamentals math and i'm not natural english speaker, but i think i'm not far of i want.

Can someone help me?
