GD&T Q&A: Composite Position with Different Material Conditions 

Hi dean can you show us how can measure or inspect composite true position at Calypso software

Thanks for the video. Can you please create a video for wall thickness calculation between external surfaces to the pattern hole, having datum shift?

hi Dean, very good video, i like it

Where did you get that micrometer tie clip from? @R. Dean Odell

Hi Dean I'm taking GD&T class , firstly I've been following your channel for a long time. I have one question for you That my instructor put I have srs doubt that he put the wrong formula for Position tolerance True position in X was 20 & in Y it was 30. True readings were 20.006 & 30.0025 Allowable tolerance was 0.03 with datum A&B Dia of hole is 10+/- 0.050 but nothing was given about the true measurements of hole. He used following formula to calculate the position tolerance 2 -√ (Xact -X)^2+(Yact -Y) Instead of 2 *√ (Xact -X)^2+(Yact -Y) His answer was 1.9935 according to formula and thereby it was out tolerance limit And mine was 0.013 by second formula within tolerance limit When I asked him he said you are taking this formula from RFS and I'm using MMC. Please clarify what should be the tolerance will help me a lot. I really wanna know whether I have invested in right instructor.
