INTRODUCTION OF METAMODEL
Metamodeling is a type of modeling used in software engineering for the analysis and construction of models applicable and useful to some predefined class of problems.
TYPES OF METAMODELS:
- Metadata modeling (MetaData Model)
- Meta-Process Modeling (MetaProcess Model)
- Executable Meta-Modeling
- Model Transformation Language
- Polynomial Metamodels.
- Neural network Metamodels.
- In metamodeling, The manufacturing process information gained from process planning, which includes all the required information of the manufacturing process of part/product, provides guidance and command information for the manufacturing process.
- The procedure of constructing metamodel The metamodel of manufacturing process information constructed in this paper is based on representation schemes and relationships in the manufacturing process and then represented by UML.
- Towards this, initial steps are taken UML ( UNIFIED MODELING LANGUAGE)
- It is a graphical method modeling language.
FRAMEWORK OF MANUFACTURING PROCESS INFORMATION MODELING BASED ON METAMODEL.
In manufacturing process information modeling, regarding to the characteristics of the process planning domain, process information modeling should conform to four rules:
Manufacturing process information model for machining process based on the metamodel, which mainly defines the process plan, operation, step, part, operator, machine, cutting tool, fixtures, measuring instrument and cutting parameter, etc.
- Process planning plays a key role in quick conversion from product design to manufacturing and improves the efficiency of product development.
- The information interactions among process planning, design, and manufacturing at the metamodel level, an effort is to be made to solve the data integration problem of product design.
