BASIC DIMENSIONS USE G D &T TOLERANCING, THE QUESTION IS I HAVE BASIC DIMENSIONS COMING FROM X & Y AXIS. AM I SUPPOSED TO "CUT" THE TOLERANCE IN HALF WHEN DIMENSIONING THE BASIC DIMENSION? example X AND Y ARE BOTH [2.077] THE TRUE POSITION CALLOUT IS ALLOWING UP TO .015 SHOULD I USE .0075 FOR X AND .0075 FOR MY Y TOLERANCE?
We have a large wall chart that gives the position so people don't have to do the math. If they can rwad the chart they can determine the tru position. It's sad really. I ordered the chart from Tec-Ease because I was tired of explaining it.....to engineers mostly. The chart has worked out well AND I don't get bugged for help to questions certain people should know already. Maybe not the best solution but it works for me. I also have a position calculator in Excel on the desktop of every PC in the quality lab. I've found if I make it really easy for them and I use bright colors and pictures I get better results.
I have worked with people in our shop for years and have successfully taught most how to calculate true position, I also made worksheets that I hand out that takes them through the process step by step. A guess is just not good enough, I keep working until they get it.
Pythagoras' theorem really isn't accurate enough for tight tolerances. You are better off using trig to solve the position...although, if people have a hard time with Pythagoras theorem, I can only imagine the headache they would get by just looking at trig formulas lol.

What the f**k are you talking about. c^2=a^2+b^2 is same as sin^2(angle)+cos^2(angle)=1
EDITED TEXT:
And trigonometry comes from Greek words trigonom(triangle)+metron(measure). Which means if you are calculating relationship of sides and angles of a triangle you are doing trigonometry.

The basic function: a^2+b^2 =c^2 is an algebraic function. It is not implicitly trigonometry. It is the
foundation of trig, but is not, by itself, trig.
