HIPP Scope

• HIPP Scope
• Complete Nominal CAD Model
• Identified Nominal Features for Inspection
• Associated Tolerances and Datums
• Tolerance Reference Standard (ex.Y14.5)
• Reference Digital Product Definition Standard
  (Y14.41)
• Associated Point Sampling Plan
• Should be DME Independent?
• It depend upon degree

3
Existing Data Formats

• WEPROM
• WErkergerechte und PROzesskettenoptimierte
  Messtechnik
• (Metrology suitable for Workshop and Optimized
  within the process flow)

CAD System
CAD Nominal Geometry
Associated Tolerances
CAD File (STEP AP214)
Tolerance File (QDAS DFD)
CMM
4
WEPROM

• Re-association at the DME
• Nominal Features with Nominal Tolerances
• Uses a proprietary format (QDAS DFD)

5
Proprietary Experience

• CAD PMI (GDT)
• CATIA V5
• UGS NX
• PTC Wildfire
• Experience Similar to WEPROM
• Summary Success is Likely!
• Confidence in a basic HIPP
• CAD GDT gt CMM

6
What Open Data Format?

• Existing STEP CAD AP QDAS DFD
• Replacement STEP CAD AP DML
• AP203e2 Translators are problematic
• Who will provide?
• What is the additional cost?
• CAX-IF experience?

7
Assuring Interoperability

• Assuring the HIPP Transaction
• What does the customer require?
• What does the DME supplier provide?
• Considering the DMIS experience
• An Applications Profile is critical to the HIPP
  effort.
• Ensures clarity in customer requirements
• Enables DME suppliers to document compliance
• Stimulates updates of reference standards
• ASME Y14.5, ASME Y14.41, DML

8
Assuring Standards Success

• Original DCX DMIS Applications Profile

9
Assuring Standards Success

• Proposal for a HIPP Applications Profile
• CAD Features Associated Tolerances (ASME Y14.5)

10
Assuring Standards Success

• Proposal for a HIPP Applications Profile
• Useful for both Proprietary and Open Standard
  Cases

• Classification Scheme
• Type Size, Form, Orientation, Runout, Profile,
  Location
• General Tolerance
• Feature Control Frame Variations
• Applicable Feature
• Datum / Degree of Freedom
• Specification Reference (e.g. Y14.5)
• Conformance Level
• Approximately 300 Specific Tolerances for Y14.5

11
Assuring Standards Success

• CAD Features and Tolerances
• Are the foundation of the HIPP strategy
• Require a practical conformance protocol
• Are Concurrent with further HIPP development
• Embeds basic HIPP in the business transaction

12
Summary

• Should a group be established to promote standard
  interface development for high-level inspection
  process planning?
• Yes, given due consideration for an Applications
  Profile from the start.
• We would be an active participant
