Résumé:
The history of industrial automation is characterized by periods of rapid change in
popular methods; these periods seem closely to world economics. the use of the industrial
machines specially computerized numerical control machines or simply CNC machines,
which became identifiable as a unique device in the 1960s, along with computer aided design
(CAD) , and computer aided manufacturing (CAM) systems, characterizes the latest trends in
the automation of manufacturing process .these technologies are leading industrial automation
through another transition.
Our work in this project is to study and design a prototype of a budget 3 axis CNC
machine that can be used as an automatic milling machine for wood, plastic and aluminium, it
also run as oxycutter, plasma cutter. We organized this project in four chapters. In the first
one we covered general informations about some basics of the CNC machines and its
evolution. The second is introducing functional analysis of the machine, which it explain the
creation process of a product (CNC machine) starting from a simple ideas and needs and
finishing with a technological solutions that can satisfied a need .The third chapter is about
the design process from sketching, dimensioning and simulating using different softwares.
The last chapter is talking about the electronics and wirings of the CNC machine with a
simple guide for how we can run and control the machine
