Geometric Dimensioning & Tolerancing : Advanced concepts

Topics covered : 

• Profile tolerance in depth

  • Relimited control of profile

  • Biased tolerance zone

  • Application of profile on Flange part

• How are Patterns toleranced and what does the callout mean with multiple examples

• Using Patterns as datums

• Refinement of Orientation and Form in Position and Profile tolerance

• Auxiliary datums - Datums apart from the datum reference frame.

• Inclined datum features - two examples

• Concept of simultaneous requirements- What does it mean ? What does it imply?

• Difference between simultaneous and seperate requirements

• Gauging with simultaneous requirements

• Gauging with seperate requirements

• Composite position control

• Composite vs Multi segment position control

• Composite Gauging

• Composite Profile control vs multi segment profile control

• Tolerancing of slots - Methods and their differences

• Using slots as Datums

• Datum Targets - Why use them ? When to use them ? How to use them ?

• Inspection with datum targets

• What is Zero positional tolerancing at MMC? with example and why use it?

• What is Projected tolerance zone ? with example and why use it?
