17 Our first attempt years ago. 17

18 End up chasing our tails. 18

19 Zoom In Aligned to P. 19

20 A little closer. 20

21 Take out the Model Aligned to P. 21

22 Take out the Model Aligned to P. 22

23 Alternative Pattern as Primary. 23

24 Aligned to P what??? 24

25 Pattern: always at MMB. 25

26 Aligned to P(M) neither is perfect. 26

27 Multiple Datum Features 27

28 Multiple Datum Features 28

29 Multiple Datum Features 29

30 Aligned to P(M) neither is perfect. 30

31 MMB Its all about the Boundaries!

32 This is our Sample being measured with our Polyworks Inspection Software.

40 Datum A

41 Datum Features B and C as Originally called out on the Print with a TOP of 0.1 for each. They all pass. So why is it when we look at our next feature we get this

42 The GD&T is not computing for this 36.6 dia. Bore. Why is that?

43 The Stop Sign, when the mouse hovers over reveals this text box. This is a good time to talk about the Maximum Material Boundaries. What they are and what they do.

44 Zoomed in on Datum Feature B

45 We are now Zoomed in on Datum Feature B Comparing, Least Squares Dia. To URAME to RAME

46 Model Removed for ease of viewing.

47 Still Need our MMB 47

48 Comparing the Inner Boundary or the Maximum Material Boundary to the RAME of Datum Feature B. There is no interference.

49 No Interference from RAME and MMB 49

50 Let s look at Datum Feature C 50

51 Remove the model. 51

52 Create the MMB and the RAME. 52

53 The RAME may not violate the MMB. 53

54 Find the Interference. 54

55 What can we do? 55

56 Which really means 56

57 All is now well, the drf computes just as it is supposed too. Please keep in mind all bore diameters will be verified with A bore gage. When C s position tolerance was.1 there was Interference with the MMB and RAME. The software did what is was supposed to. Not allow us to continue with our inspection.

58 Seeing Datum Shift Because Shift Happens! AGCO

59 Datum Shift is not a bonus. 59

60 AST Alignment 60

61 Zoom in on Secondary Datum Feature 61

62 Aligned AST w/o Modifiers 62

63 Aligned AS(M)T(M) 63

64 A little shift can make a difference. 64

65 Pass or Fail. 65

66 Thank you, and Thank a Farmer.
