三维复杂槽型铣刀片槽型优选技术的研究
|
摘要
为研究铣刀片三维复杂槽型几何单元对刀具切削性能的影响,我们设计了槽型优选测试系统。该系统集测量与分析于一体,可测得铣削波形的瞬时值,灵敏度高,抗干扰性好,能消除系统和周围环境引起的零漂,是进行本课题分析的重要手段。槽型优选测试系统采集的数据和处理为下面利用功率谱分析评估槽型优劣和进行槽型典型几何单元的提取、比较提供了依据,从而为槽型优选做好了先期工作。
在槽型优选测试系统实验的基础上,我们引入了信号分析工具——功率谱分析,作为评估槽型优劣的一个标准。在断续切削中,铣削波形可被看作周期函数,将单齿铣削波形看成为脉冲函数,经过傅立叶变换,可以表示为一个按特定的基本频率变动的正弦波形的分量和许多个按基本频率的整数倍而变动的正弦波形的分量叠加而成,讨论所获得的频谱函数,是研究三维复杂槽型铣刀片切削性能的主要环节,以便了解影响单齿铣削波形幅值谱图的各种因素,并从功率谱图的组成情况来考察动态铣削波形的特性,从而进行槽型的设计和优选。
从提高三维复杂槽型铣刀片的切削性能和可靠性出发,对切削参数和不同槽型铣刀片切削性能之间的关系进行了深入分析,并给出了铣削力在前刀面上的分布函数模型;结合槽型优选测试系统实验,我们对三维复杂槽型铣刀片槽型典型几何单元及其组合进行了系统的分析讨论,并对刀片几何参数进行了评价优化。在分析了切削参数和刀片几何参数与不同槽型刀片切削性能之间的关系的基础上,给出了铣刀片槽型开发和设计的准则。
In order to find out the influence on the cutter cutting capability caused by milling insert grooves, we design the groove testing system. This system integrates measure with analysis and it can be used to test the instantaneous value of the milling wave. The system has high delicacy and its anti-jamming is good, it is an important means to deal with this task. Evaluating the grooves by the spectral analysis and distilling and contrasting the groove geometry segment is based on the acquisition data and processing of the groove testing system, so it is preparing for the groove optimization.
Based on the groove testing system, we induced the spectral analysis which is the signal analysis tool into evaluating the grooves, and used it as an evaluating standard. In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.
In order to improve the cutting capability and reliability of the complex three-dimension grooves milling insert, we deeply discussed about the relation between cutting parameters and the cutting capability of different grooves inserts and provided the milling force mathematical model. Based on the groove testing system,
we deeply discussed and analyzed the typical groove geometry segments and their combination of the complex three-dimension grooves milling insert, what’s more, we evaluated and optimized the geometry parameters of the insert. Based on the relation between cutting parameters, geometry parameters and the cutting capability of different grooves inserts, we provide the exploitation and design rules of the milling insert grooves.
