Inspection Engineering / Sr. Applications Engineer

Inspection Engineering / Sr. Applications Engineer I took this class in October 2012 and had Jaime Dadez as my instructor. This was an excellent course and I would recommend it to everyone who is a layout inspector or quality engineer. It is one thing to get the CMM to move and measure features/define characteristics, but… View Article

Geometric Dimensioning and Tolerancing Quiz ASME Y14.5 – 2009

So you think you know Geometric Dimensioning and Tolerancing (GD&T)? Take our real-time interactive quiz. You’ll receive your score immediately after completing the quiz.

This test is for the evaluation of knowledge and skills in Geometric Dimensioning & Tolerancing per the ASME Y14.5M-2009 standard.

1. Which statement best describes what the ASME-Y14.5M-2009 covers?
2. Using GD&T:
3. How can properly implemented GD&T save money in the manufacturing process?
4. What is a Basic Dimension?
5. What is a Feature Control Frame?

Select the description for each Geometric Characteristic Symbol:


6. a
7. b
8. c
9. d
10. e
11. f
12. g
13. h
14. i
15. j
16. k
17. l
18. m
19. n
20. What is a "Material Condition Modifier?"
21. A positional tolerance defines:
22. Which is the correct definition of regardless of feature size?
23. What is "Rule 1" (i.e. the "Envelope Rule" or the "Perfect form at MMC Rule"), and what effect does it have, if any, on flatness? ...straightness? ...perpendicularity? ...position?
24. What is the difference between a Datum and a Datum Feature?
25. What is a Datum Reference Frame?
26. What is MMC Virtual Condition?

Refer to Figure 1 for the following questions:


quiz-fig1

27. What is the MMC size of one of the holes?
28. What is the MMC Virtual Condition size of one of the holes?
29. What is the LMC size of one of the holes?
30. How much total positional tolerance would be available for one hole if that hole was produced at a size of Ø.255?

Refer to Figure 2 for the following questions:


quiz-fig2

31. Datum feature "B" was manufactured at a related actual mating size (RAME) of 2.49. Datum feature "C" was manufactured at an RAME of 3.01. Now how much total positional tolerance does that one hole (relative to the other holes in the pattern) have? (The considered hole is still Ø.255.)
32. With the same actual datum feature sizes and considered hole size defined in the previous question, how much extra tolerance does the 4-hole pattern have relative to the "center of the part?" (Datum features "B" and "C" define the "Center" of the part.)
