Digital forms of describing Industry 4.0 objects

Abstract

The task is to project item digital model which is planned to be manufactured in cyber and physical production of the Industry 4.0. Item digital model can be classified as item digital replica, item digital shadow and item digital twin. Item digital model is a set of construction, program and technological documentation prepared electronically with automatic system of projection. Item digital shadow is a set of item digital replica documentation enhanced with mathematical equations with restrictions to describe physical and chemical properties of the item materials and its components. Details to describe the item digital shadow are defined with types of tests done with modelling and virtualization. Item digital twin is a finished form of item properties description done electronically (drawings, schemes, formulas and other) and successful physical tests of the whole cycle. The scheme is given for the item life cycle of the item designing item digital model. The scheme of production section and Industry 4.0 smart factory virtual environment components is described oriented to manufacture the items by its digital models.
