Abstract


The subject of this application Mechatronics System Design of CNC machine tools and methods for the transformation of structural design, is designed to achieve a high level of static and dynamic stiffness; Vice movement between the friction coefficient of small, non-drive space; easy operation and maintenance. And economic control of the CNC lathe-model analysis of the principle of the whole system, a key factor in accuracy, analysis of the impact of machine tool positioning accuracy of the sources of error, put forward to improve the methods and tools used in the design of the structure.First of all, CNC lathe for general transformation into mechanical Servo System to the part of the design and calculation, including: the system load, the moving parts of inertia calculation, the choice of stepping motor, ball screw and the choice of terms, Ball Screws Checking such as the stiffness. Followed by the transformation of the economy after the NC to lathe into the servo control system to establish the principle model. According to the servo feed system control theory model of the servo-driven components of the servo precision, mechanical servo-drive transmission components for precision analysis of the economic impact analysis of the NC machine tool positioning accuracy of the main factors.General NC machine tool of a certain transformation of the economy, practicality and stability. Involves the transformation of its mechanical, electrical, computer and other fields, the topics for the use of information technology on the traditional mechanical processing equipment technology provides a precise and reliable design.
