Abstract:

随着中国工业的不断发展,产业结构和技术水平也在不断升级,复杂零部件进行精密加工的需求越来越大。数控机床具有加工精度高、加工时间短等优点,是现代装备制造业必不可少的加工设备。本文将高材料去除率状态下切削力扰动作为限制条件,提出了适用于高去除率工艺的数控机床速度规划算法。通过对S型曲面加工实验,结果表明本文提出的速度规划算法可以有效提高加工效率,能够在一定程度上提高加工精度。
As China’s industrial development continues, the industrial structure and technological level are constantly upgrading, and the demand for precision processing of complex parts is increasing. CNC machine tools have the advantages of high machining accuracy and short processing time, and are essential machining equipment in modern equipment manufacturing industry. In this article, the cutting force disturbance under the high material removal rate condition is taken as the limiting condition, and a speed planning algorithm suitable for high material removal rate processes of CNC machine tools is proposed. Through the S-shaped surface machining experiment, the results show that the speed planning algorithm proposed in this article can effectively improve processing efficiency and can to some extent improve processing accuracy.
