Question

Fundamental of tool design 6th edition.

TRUF/FALSE Read each statement carefully. If the statement is true, write T. f the statement is false, write F. (IS points) 1. There is a datum in conventional dimensioning. 2. In GD&T, location dimensions can have bilateral tolerances 3. In GD&T, angular dimensions can have limit dimensions. 4. Manufacturing processes should be specified for a geometric tolerance. (e.g, drill or ream). 5. The LMC of hole is when it is at its dimensional upper limit. 6. 7. A clearance fit is a specific type of a transition fit. 8. Tolerance is allowance. 9. If the primary datum feature is a planar surface, it should be controlled by a flatness tolerance. 10. A datum can be a point, line or plane. 11. For a profile tolerance, datum(s) should always be specified. 12, Rule #1 cannot be overridden. 13, Rule #2 says that if a geometric tolerance is not modified by MMC, the material condition is LMC. 14. A primary datum which is a center axis of a hole takes away 5 degrees of freedom out of 6. 15. A geometric tolerance can have maximum 4 datums. LMC hole-LMC shaft = Clearance
