摘要
动态移动切削阻力载荷对高速数控裁床加工过程中刀具形变及其剪裁误差具有的重要影响,提出了一种适用多层布料/皮革曲线剪裁路径的刀具形变及其误差计算方法;建立了动态负载条件下可伸缩刀具的挠度与转角方程,进而推导出高频振动裁刀剪裁误差及其随切削深度变化规律;计算结果表明,数控布料/皮革剪裁刀的动态载荷、高频振动参数、切削深度对剪裁误差具有重要影响,深入剖析高层数控裁床的加工机理,动态参数数据分析,对于提高机床加工效率,降低加工误差,提高刀具使用寿命具有一定的工程应用价值。
Dynamic ousting resistance of moving load is an important, feotor affecting the tool deformation, during operation of high -layer CNC cutting machine. A tool deformation and error calculation method that is suitable to the multi-layer clothing/leather cutting in curve path was proposed. And deflection and rotating angle equation were established under the eondition of dynamic load, and thus we can dedues the cutting error of the machine tool with high-frequency vibration and its change rule correlated with cutting deptli. The lalctilation result reveals that factors of dynamic load, High frequency vibration parameters, and cutting depth have strong inilucncc on the cutting error. Deeply research on machining mechanism and dynamic parameters analysis of thfe high -layer CNC cutting machine has eertain engineering application value in improving work efficiency, reducing machining error, and prolonging service life of cutting tools.
