Geometric Dimensioning & Tolerancing : Advanced concepts

• Geometric Tolerancing of Patterns of features
• Using Composite position control for controlling patterns and features
• How to use Datum targets on irregular shape parts
• Projected Tolerance zone
• Methodology of tolerancing slots
• Comparison of composite control vs multi segment control
• Refinement of orientation of form controls 

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?
