伴随着现代化工业的高速发展,对产品表面粗糙度的检测精度要求不但越来越高,而且还要动态地反映某种变化规律。利用微处理机动态反映切削表面粗糙度是近年来切削加工领域研究的一个新课题。如在图1所示系统中,反映切削过程的各参数经微处理机模型处理后,由信号放大器给显示仪器输送信息,以此来检测微观不平度的大小或控制加工工件的质量。显然,建立正确的数学模型是动态反映切削表面微观不平度的关
With the rapid development of modern industry, the requirements for the detection accuracy of the surface roughness of products are not only higher and higher, but also dynamically reflect some variation rule. Using the microprocessor to dynamically reflect the cutting surface roughness is a new topic in the field of cutting machining in recent years. As shown in Figure 1, the parameters reflecting the cutting process are processed by the microprocessor model, and the signal amplifier transmits the information to the display instrument, so as to detect the size of the micro-irregularity or control the quality of the processed workpiece. Obviously, the establishment of the correct mathematical model is to dynamically reflect the micro-surface roughness of the cutting off
