Abstract

The speed planning of the feed system is an important factor affecting the machining accuracy and efficiency of high-speed and high-precision machine tools. Existing research on speed planning for CNC machine tools primarily focuses on reducing speed fluctuations and avoiding sudden changes in acceleration and jerk to improve machining accuracy and surface quality. They do not explicitly consider the comprehensive action of each subsystem. The load inertia ratio is one of the key parameters to study the comprehensive effect of subsystems. This paper fills this gap by elucidating the evolution of feed system performance under the combined effects of load inertia ratio and speed planning, starting from the dynamic fundamental mechanisms. By eliminating the influence of servo control, the influence of speed planning on the dynamic performance of the feed system under different load inertia ratios is studied. To further improve the dynamic performance of the feed system, the speed planning strategy should be adjusted according to the load inertia ratio. This paper provides a theoretical basis for speed planning considering the influence of the load inertia ratio.

负载惯量比对进给传动系统速度规划策略的影响研究

进给系统的速度规划是影响高速、高精度机床加工精度和效率的重要因素。现有的数控机床速度规划研究主要集中在减小速度波动，避免加速度和猛跳的突然变化，以提高加工精度和表面质量。它们没有明确地考虑每个子系统的综合作用。负载惯量比是研究子系统综合效能的关键参数之一。本文从动力基本机理出发，阐述了负载惯量比和速度规划共同作用下进给系统性能的演变规律，填补了这一空白。在消除伺服控制影响的基础上，研究了不同负载惯性比下速度规划对进给系统动态性能的影响。为进一步提高进给系统的动态性能，应根据负载惯量比调整速度规划策略。为考虑负载惯量比影响的转速规划提供了理论依据。
