MECHANICAL DESIGN ELEMENTS FOR MAKING MACHINES WITH CNC
Used to shape solid materials, mainly metals. Its main feature is its lack of mobility, because they are usually stationary machines. The modeling of the piece is performed by removing some of the material, which can be done in metal cutting, stamping, cutting or EDM.
Machine tools can use a variety of energy sources. The human and animal power are options, such as the energy obtained through the use of water wheels. However, the actual development of machine tools began after the invention of the steam engine, which led to the Industrial Revolution. Today, most of them run on electricity.
Machine tools can be operated manually or by automatic control. Early machines used flywheels to stabilize their motion and had complex systems of gears and levers to control the machine and working parts
Shortly thereafter developed digital control systems. The CNC machines used a series of numbers punched on paper tape or punch cards to control their movement. In the 60 computers were added to increase the flexibility of the process. Such machines began to be called CNC machines, or machines, Computer Numeric Control. CNC machines and CNC sequences can be repeated again and again with precision, and can produce more complex parts that can make the most experienced operator.
