I am in discussion with another engineer here trying to hash out the calculation for Position of a threaded hole within a bolt circle. The equation works out to be 2*sqrt(x(dev)^2 + y(dev)^2). I am looking for the explaination of how Quindos arrives at this. The 2x multiplier is where he is gettng hung
Explain it to him VERY SLOWLY. Position is (usually) a DIAMETRIC result.
SQRT((x_dev)^2 + (y_dev)^2) gives a RADIAL distance from x,y nominal and x,y actual.
MULTIPLY by 2 and you get a resultant DIAMETER. If he still doesn't understand, have him take off his engineer dunce cap and draw a circle on a piece of paper. Ask him what the distance across it would be. If he doesn't answer DIAMETER, just shoot him.
Thanks guys. I believe he came to an understanding. I am still interested in the Quindos approach to standard ISO DIN 1101 is referenced and the hard code in the calculation. Without see the reference of the position formula directly back to position callout explicitly in an industry standard, some have a hard time arriving at common practice.
