It will cost a company in the form of money, time, materials, or 5. D customer satisfaction 6. Manufacturers need to interpret details to select a capable process, 7.
D notes 3. None — There are no flags polygons around the general note 6. C numbers 7. C and F Millimeters Degrees No; because the user cannot determine if they are decimal degrees A hole 4.
None; there is no location relationship tolerance geometric 5. C tolerance for this hole 6. More difficult because coordinate tolerances cannot express many 7.
B of the relationships required for this part to function, and coordinate 8. B tolerances are more vague specifications 9. Two parallel planes 5. Non-opposed 7. Dimensions B, C, and D 3. Dimension B: B apart; dimension D: 8mm cylinder 5. Title block tolerance 6. Dimension A: the independency symbol is specified 7. Yes 4. Yes 5. Yes 6. Using an optical comparator 8. Yes 2. No; the diameter symbol is not allowed 5. No; must be applied to a cylindrical surface 2. Yes; circularity can be applied to each circular element of a cone 3.
None; datum features are not referenced in the feature control 2. A frames 3. Datum feature A 4. A minimum of three points of contact 5. Three degrees of freedom 6. Nothing is specified; a general angular tolerance would apply 7. Translation along the X, Y, and Z axes and u, v, w rotation around the 8. T X, Y, and Z axes 9. Translation along the Z axis and u, v rotation around the X and Y axes 9. Translation along the Y axis and w rotation around the Z axis Datum reference frame symbol Datum feature symbol Translation along the Z axis and u, v rotation around the X and Y axes 8.
Yes, the position tolerance uses a complete datum reference frame constraining all 6 degrees of freedom; the part will make the same part to gage contact every time 9. Translation along the X and Y axes and u, v rotation around the X and Y axes 7. A — zero 2. B D — Zero between holes; 0.
B bolt pattern 6. A pin with a B 2 Surface E 3 Yes 4 2 parallel planes 0. Yes B. No, cannot be applied to a pattern C. Yes D. Yes E. No, the MMC modifier is not allowed with a surface application F. No, the diameter symbol is not allowed with a surface application 7. A No; the tolerance value must be less than the size tolerance 2. A B No; the hole is not parallel to datum feature A 3. A E No; the surface is not parallel to datum feature A 6. A F No; the tolerance feature and the datum feature cannot be the same feature 2.
The functional gage cannot be drawn because the hole is not parallel to datum A 3. Use a dial indicator and a height gage Rest the part on datum simulator C and zero the indicator on the surface and move it around The full indicator reading must be equal or less than 0. D perpendicular to datum plane B 4. The tangent plane must be within the tolerance zone and the 5. C low points of the surface do not 6. Yes 7. Yes 8. No; a datum reference is required 9.
T 6 A plane primary and a variable cylinder secondary 8. T 7 Orientation and location 2. B 4 Two coaxial circles separated by 0.
A 6 A single variable diameter cylinder 7. B 7 Coaxiality, parallelism, and circularity 8. F 3 Yes 4 Two coaxial circles separated by 0. C 2 The median points of the 56mm diameter 3.
B 6 A variable size cylinder contracted about the 7. C high points of the surface 8. A 7 Location and orientation 2. No; a datum reference is required B. No; the MMC modifiers are not allowed C. No; concentricity should be applied to a diameter, not symmetry D. No; the LMC modifier is not allowed E.
Yes F. No, the projected tolerance zone modifier is not allowed G. Yes H. Yes J. A Yes 8. A Location, orientation, and form 2.
Fundamentals of Geometric Dimensioning and Tolerancing
Fundamentals of Geometric Dimensioning and Tolerancing. Alex Krulikowski. This book clearly organizes geometric dimensioning and tolerancing fundamentals into small, logical units for step-by-step understanding. Measurable performance objectives help you and your students assess their progress.
