Název v původním jazyce

Simulation of dynamics of CNC meandrine tool magazine

Popis výsledku v původním jazyce

Article deals with analytical description of dynamical behavior of meandrine tools magazine of CNC machine. Mechanism of magazine is analyzed from the point of view of kinetic energy and mechanical power of individual parts with translational, rotational and general planar motion, and inserted tools. Magazine works in displacement, velocity and current feedback loop with velocity feedforward. The principal equation of motion of magazine is derived using method of equivalent inertia in combination with mathematical description of electric motor and PID controllers. Numerical solution of derived equations leads to determination of torque of servo-motor needed for complying of required motion dynamics. Position control error of the system is calculated as well. Weight of tools and their position within the magazine are considered as random quantities with uniform distribution. It is shown in the article that not only weight of tools but also their distribution within the magazine are important conditions influencing load of servo-motor.
