The design and implementation of the three-dimensional motion platform control system trajectory algorithm

Abstract

Three-dimensional motion platform control system is very comprehensive, and it is a CNC(Computer Numerical Control)system that is controlled by the digital information . Open CNC system is the mainstream of today's CNC technology, its greatest features are that it has the openness, interoperability, scalability, portability, scalability and so on. Interpolation module is the core technology of numerical control system, its quality directly impacts the quality of CNC machining technology, so that we now need to enhance and improve the CNC interpolation technology links. This paper studies the algorithm of the trajectory, Firstly, describes simply the development status and trends of the numerical control system , and the status and trends interpolation technology; Then, describes the digital interpolation algorithm used in this article to achieve linear, circular, elliptical, parabolic, hyperbolic interpolation algorithm. Then explains that uses the point by point comparison method, the time division method of data sampling interpolation to achieve linear and circular interpolation motion, and finally studies the

acceleration and deceleration theory of the CNC system control.
