silviosi, I've been thinking about this since you first posted and when you brought up the Pythagorean formula, that seemed to be the simplest route to go. Using my coaster, that my coffee was sitting on, I made a rough sketch of two right angles and then marked it up. Basically, a right angle caliper, similar to what westcoin described but one being fixed on the table, with measurements and the other that could slide, with an adjustable diagonal axis too. Not sure about cost or how easy it would be to make but a basic concept that would work. See what you think.

Thanks to all for the theorems or thinking about.
Seem was not well understood the questions and with your permission I will formulate different.
I look for the designs median axes. Mean what it is the accepted or legal line which will separate the design of the coins in half. It is the only thing missing me. The tool it is already done.
Hope this formulation it is more compressive.
thanks

It just kicked in for me what you were looking for. Sorry, silviosi, I'm not the sharpest knife in the drawer. You are looking for information on the correct orientation of the obverse and reverse of many different coin designs, I get it now. The one below would be very easy, most are not though. For example, you cannot always use the date and LIBERTY, on a Lincoln Cent, for your horizontal, because they are not always true. You are looking for the TRUE, North, South, East and West or 0, 90,180 and 270 degree points, on each design. EASY  NOT EASY

MAKE you catch my though. I know it is not easy this. You are a really scientific person.
The tool is ready, missing me this information for correct tables. To marketing is easy, but I want to be precise and users to has the good tables informations so all will be satisfy.

I have actually looked for this info before on different denominations and could not find it.

Hold on a second. Let me finish my Christmas shopping, and come back. If we are trying surpass the 180° CW or CCW being a coin flip or medal flip. I might to need to find a new program. Thanks, Doug.

Me I ask the Mint, I thinking if I work with them many years the can share this information, BUT NOT because it is internal data and I understand,
Sure each denomination has many design changes and this axes will change every times. This it is the most harder part of this design.
I hope will we come to something here. I believe in you guys (no offend for women's).

He is referring to angular velocity at a specific point in time. How obverse and reverse coincide with one and another, I believe. Die Rotation. A Caliper a standard piece and trigonometry as well as algebra will be necessary.

@ suttodh: All my calculus are base on special mathematics and not Euclidian's. Why? because the Euclidean is approximative.

Radial run out and a known standard is the first place to start. I am trying to enlighten the community on what you are trying to achieve.

Quote: angular velocity at a specific point in time. This was determinate by the Mint as acceptable at plus or minus 2 degrees. This angular velocity with acceptable deviations are more to be the normal for the different years due to the hammer and anvil ways to be hold on the shafts. Also vertical and horizontals forces are involved and the usurer of the presses parts are in the game also.

Basic tolerance would be four degrees.
