what are tolerances
Mukesh D.
Supreeta N.
The use of coordinate tolerances for cylindrical holes results in tolerance zones. A. Cylindrical B. Rectangular C. Parallel D. Uniform. 13. To establish a virtual condition (acceptance boundary) is required. A. An (M) symbol in the tolerance portion of a feature control frame. B. An (M) symbol in the datum portion of a feature control frame. C. A diameter symbol in the tolerance portion of a feature control frame. D. All of the above. 8. Where the counterbore symbol is specified, one additional consideration would be. A. The specification of the (SF) symbol. B. The specification of the S symbol. C. The specification of the depth symbol. D. The specification of the symbol. 14. How does Rule #1 affect the application of a flatness tolerance applied to a surface? A. Where Rule #1 exists, flatness cannot be applied. B. The flatness tolerance value must be equal to the size tolerance. C. The flatness tolerance value must be less than the size tolerance. D. The flatness tolerance value must be greater than the size tolerance. 9. What does the (CF) modifier indicate? A. A critical feature. B. A compound feature pattern exists. C. Two features or features of size are to be treated as one feature of size. D. Two surfaces are produced with the same operation(s). 15. Where no geometric tolerances are specified, the worst-case boundary of a hole is referred to as: A. An inner boundary. B. A nominal boundary. C. A virtual condition. D. A related actual mating envelope. 10. Where the countersink symbol is specified, one additional consideration would be. A. To specify a depth. B. To specify the angle. C. To specify a datum reference. D. To specify the origin symbol. 16. The virtual condition of feature of size is a constant boundary generated by the collective effects of the largest feature of size plus the applicable geometric tolerance. A. An internal. B. An external. C. A nominal. D. All of the above. 11. When inspecting a feature of size where Rule #1 applies, two items must be inspected, the MMC boundary and the: A. MMC size. B. LMC local size. C. Minimum size. D. Related actual mating envelope. 17. How many datum reference frames can a part have? A. 1. B. 2. C. 3. D. No limit (theoretically). 12. Which type of surface deviation is controlled by a cylindricity tolerance but not by a circularity tolerance? A. Ovality. B. Taper. C. Lobing. D. None of the above.
