这是一篇高速加工数控系统开发方面的理论性较强的文章。众所周知,加减速控制是CNC系统中插补器的一项十分重要的控制功能,它对加工精度和系统性能都有着十分重要的影响。特别是在高速加工中,加减速就显得尤为重要。文中,作者在分别分析了数控系统中直线形、三角函数形、指数形、S形、直线加抛物线形加减速控制曲线的基础上,对这几种控制方法各自的优缺点及适用场合进行了比较,并着重讨论了S曲线加减速算法。
This is a high speed machining numerical control system development theory of the article. It is well-known that acceleration and deceleration control is a very important control function of interpolator in CNC system and it has a very important influence on machining accuracy and system performance. Especially in high-speed machining, acceleration and deceleration is particularly important. In this paper, based on the analysis of linear, trigonometric, exponential, S-shaped and linear plus parabolic acceleration and deceleration control curves in numerical control system, the author has carried out the respective advantages and disadvantages and applicable situations of these control methods Compared and focused on the S-curve acceleration and deceleration algorithm.
