Position of a hole
[edit]Hi. What is the formula for calculating position of hole?— Preceding unsigned comment added by 20.133.1.1 (talk) 11:40, 24 July 2013 (UTC)
True Position Formula
[edit]
The true position formula is 2x(square root (x squared + y squared))
True position is simply finding the diameter of a circle. To do this, we find the radius of the tolerance circle. This radius is the hypotenuse found by employing the pythagorean theorem, which is a squared + b squared = c squared. C squared is the hypotenuse. Use the values of the x and y coordinates and compare them to the print position. Subtracting these x and y values will give us A and B to use in the formula. Square both A and B and add them together. Find the square root of the value you just found. We find the square root because we are looking for C squared. When we have a value for C we have the hypotenuse from the x and y deviation from the nominal point. The hypotenuse is a radius from which we can make a circle. Multiply the hypotenuse by 2 to find the diameter. This diameter is the value of true position. Sketch out a example and apply the pythagorean theorem, you'll see there is not magic involved. — Preceding unsigned comment added by Don Schrank (talk • contribs) 23:01, 15 October 2016 (UTC)
