金属切削过程中的建模与仿真

Modeling and Simulation in process of Metal Cutting

模型在产品制造中具有重要作用,对产品制造中的模型及其仿真作了分析,并讨论了产品制造中切削加工过程动力学模型的确定方法。首先直接获取冲击响应的原始信号,再将所有输入输出信号同时作高通和带通滤波,抑制了有害的干扰信号。数据处理时,在时域中按最小二乘法估计参数,参数估计收敛快,使观测总时间很短。因此,该方法简单实用,对加工过程具有十分重要的时间应用价值。

Models are very important in product manufacturing. The models and simulation application to product manufacturing are classified in this paper, and the method of dynamics model finding is discussed in process of metal cutting. First, the signal of pulse response is obtained directly. Then, the input signals and output signals are processed by both low-pass-filter and high-pass-filter. Finally, the parameter is calculated.
