Types of Interface:

An interface may be regarded like an aggregate of conditions, rules and conventions which defined the information exchange, among two communicating objects. An object in our context may be human, modules, software, computer hardware or manufacturing processes. In principle, three kinds of interfaces may be distinguished including language interfaces, procedural interfaces and descriptive interfaces. The CAD system should be able of exchanging data with the manufacturing system components are as illustrated.

The language or user interface is the window through which the user may communicate with the CAD module. The user employs the pictorials, icons menus or textual languages to describe design and manufacturing problems. The textual languages are till the most significant means of user/system communication. Though, the interactive graphic languages are raising gaining importance, they are easier to learn and offer a more natural method of user/agent communication.
