Referser of GD&T Principles from ASME Y14.5 M 1994: symbols, material condition symbols, boundaries, converting from plus and minus tolerancing to position tolerancing
Selecting datum features
Placement of symbols
Virtual and resultant conditions
13:30 - 16:00
Methods of position tolerance verification (Boundary method vs Tolerance zone method)
Floating and fixed fastener assembly tolerancing, Consideration for threaded features, Tolerance distribution for projected tolerance zones
Discussion
16:00 - 17:00
Day Two
Session
Bilateral position tolerancing, different position tolerance at each end of a hole, different tolerance for hole and counter bores, position tolerance of a noncircular feature of size
9:00 - 12:00
Pattern location, Non parallel axis hole patterns, Multilevel composite and two single segments position and profile tolerancing
Using composite and two single segments position tolerance on complex assemblies
Strategy for tolerancing parts
Demonstration on CMM
12: 00 - 12:30
New concepts in Y14.5-2009 are discussed and compared to the 1994 standard) such as: New symbology and rule changes, Moveable datum target symbol, Datum translation symbol, specifying degree of freedom symbology, calculating the correct material condition boundaries (Maximum material boundary, least material boundary, and Regardless of material boundary). Datum feature basic symbology, Specifying the desired Material Boundary, Datum feature patterns referenced at MMB, LMB and RMB, Datum feature simulators, irregular datum feature of size, repetitive patterns, two and three level composite position and profile controls
