Introduction

Modern computer numerical control (CNC) machines fulfill numerous complicated operations. Therefore, to understand them it is necessary to know how it works. Nowadays, CNC machines can process complicated shapes of pars, as well as making machining more automated than before.

Application of CNC machines guarantee the quality of machined parts and repeatability of its production quality. Thus,

Principals of cnc machining

Numerically controlled (CNC) machine tool, robot, another object be called the way of managing on the basis of the prepared control program will the main indicators of which are given in digital form. Here, the managing software (Fig. 1.1) is a set of commands in problems oriented programming language, which corresponds to a given algorithm operation of the machine, a robot, another object for the implementation of technology, transport and auxiliary operations. Under the CNC will understand the device outputs a control influence on the controlling devices of the object in accordance with the managing softwares, algorithms, processing and information on the state of the managed object.

To work with CNC machines it is necessary to know special rules of programming.
