The traditional Z-Map was re-invented to a common data model for representation of geometry, attributes, physical states and other characteristics of novel manufacturing processes, which may include a multi-step operation of milling, turning, moulding and EDM (Electro-Discharge Machining), etc. The method is used to integrate these discrete point unit processes into a multi-step model for pervasive processes design and verification. A second patent has been filed to apply this method in mould design and verification.

1. AN OBJECT REPRESENTATION METHOD
For Continuum Multi-step Mould-Machining Design and Verification
The traditional Z-Map was re-invented to a common data model
for representation of geometry, attributes, physical states and
other characteristics of novel manufacturing processes, which may
include a multi-step operation of milling, turning, moulding and
EDM (Electro-Discharge Machining), etc. The method is used to
integrate these discrete point unit processes into a multi-step
model for pervasive processes design and verification. A second
patent has been filed to apply this method in mould design and
verification.
