摘要:

增大铣削加工参数可提高加工效率,却易产生加工颤振的问题,因此提出一种同时考虑铣削静动态性能和时变刀具磨损影响的稳定性判别方法。先依托铣削力模型建立考虑径向切削深度与刀具直径的三维铣削叶瓣稳定图,确定基础加工参数。再通过频域信号处理剔除主轴转频干扰,判别实际加工的铣削稳定性;同时基于铣削刃口系数变化监测刀具磨损,并将磨损因素融入判别体系。铣削稳定性在线判别实验结果表明,所提方法在保证工艺稳定的前提下提高了材料去除率。

关键词: 铣削稳定性, 材料去除率, 刀具磨损, 动态判别

Abstract:

Increasing milling parameters improves machining efficiency but tends to cause chatter. To address this issue, this paper proposes a stability identification method that considers the static and dynamic characteristics of the milling process as well as the influence of timevarying tool wear. First, a threedimensional stability lobe diagram, incorporating radial cutting depth and tool diameter, is established based on the milling force model to determine the basic machining parameters. Second, frequencydomain signal processing is adopted to eliminate interference from spindle rotational frequency and to identify the actual stability state. Meanwhile, tool wear is monitored based on variations in cutting edge coefficients, and the wear factor is integrated into the identification system. Online identification test results verify that the proposed method can increase the material removal rate while ensuring process stability.

Key words: milling stability, material removal rate, tool wear, dynamic characteristics
