The Study of S-Shaped Acceleration and Deceleration Curve and the Trajectory Planning Strategy Analysis

Article Preview

Abstract:

The invention of the Numerical Control (NC) technology have brought the new revolution of manufacturing since 20th century intermediate stage. Computer Numerical Control (CNC ) technology is the foundation of the modern manufacturing technology, integrating the traditional manufacturing technology, modern control technology and modern optical-electromechanical technology.[1,2]As the core of CNC technology, CNC system is requesting higher precision and higher speed as it develops. So it is necessary to meet the requirements of the machining surface quality and avoid the occurrences of the processing speed decline or even stall, which depends on the good controls of the acceleration and deceleration of the feed shaft [3].This article briefly analyzes some existing strategies of the acceleration and deceleration, then mainly introduces the s-shaped acceleration and deceleration curve method and the trajectory planning strategy of it.
