2. USE OF CAX SYSTEMS IN THE INTELLIGENT 
MANUFACTURING
CA systems are computer systems that are intended to 
support of activities at all stages of manufacturing – from 
development and design of component, production planning 
to production and assembly, storage and expedition.
Central production planning/manufacturing systems rely on 
centralized communication, are rigid, lack scalability and 
robustness, and have a high cost of integration. Mass 
Production Systems place emphasis on the reduction of 
products’ costs and full utilization of plant capacity.
This manufacturing approach resulted in inflexible plants, 
associated with work in process and finished goods 
inventories.
Computer-Aided Design (CAD)/ Computer Aided
Manufacturing (CAM) systems integrate different tools (e.g., 
e-mail, multimedia, 3D CAD geometry viewer) in 
a distributed multimedia designing environment through the 
Internet (e.g.). In CAD, the computers are used in the design 
and analysis of products and processes. In CAM, the 
computers are used
directly to control and monitor the 
machines/ processes in real time or offline to support 
manufacturing operations (e.g., process planning).
Computer integrated manufacturing (CIM) systems have 
been used to integrate different areas within 
manufacturing enterprises. They use a graphical user 
interface within a programming environment and 
incorporate multimedia packages to facilitate the 
dissemination of product information (e.g.) 
3. THE REQUIREMENTS TO INTELLIGENT 
MANUFACTURING SYSTEM
The automation of the intelligent manufacturing process can 
be run in term of the manufacturing profile, material flow 
and information flow. These basic elements of the 
manufacturing process are usually automated together in 
praxis. The task of the intelligent manufacturing process
control is to provide the process running in the status of 
dynamical stability and the replacement in the equilibrium 
status on the same or acceptable standard by the deviation of 
the equilibrium status. It is necessary to control and direct 
the main manufacturing processes that have the required 
functions. It could be to run more hard manufacturing 
processes together and also individually in the 
manufacturing process and all these processes could be to 
control by specific method. This method is named as the 
manufacturing process control.
The process control is characteristic as the process 
organization in system that provides the achievement of the 
required final state. But it is necessary to know its output for 
the manufacturing process control in the relatively closed 
system that it could be to influence the inputs back, to 
eliminate the ineligible influences of the environment, to 
reorganize the system internal structure so that will be to 
achieve the required final state. The necessary element of 
control system is the feedback.
The utilization of this information for the manufacturing 
process control could be only then if it is known the noted 
model of system behavior by means of that it is possible to 
create the control algorithm and technical system for its 
realization by defined aim. The required final state has to be 
real, achievable, the algorithm realizable and the information 
provision comfortable.
