摘要
本文针对GCN—2型表面粗糙度测试仪,设计了微机接口,对表面粗糙度特征参数实现在线分析计算;并对表面粗糙度信号进行频域和时域分析,进而为查找产生误差的根源提供依据。
The microprocessor interface for the GCN ?2 type roughometer is designed. On-line analysis and calculation for the characteristic parameter of surface roughness are achieved. Also, the frequency domain and time domain of the surface roughness signals are analyzed. Based on these results, reasons leading to error can be found.
