摘　　要：为了提高外圆磨削加工零件表面粗糙度的测量效率,可以采用在线测量的方法。基于CCD成像技术,利用激光图谱比较法以及图像傅立叶变换后的能量谱,对外圆纵向磨削后的零件表面粗糙度进行非接触式在线测量,并判定加工零件表面粗糙度的等级。使用的测量方法,可以实现在线检测表面粗糙度的目的,达到了预想的效果。In order to increase measurement efficiency of workpieces surface roughness during cylindrical grinding process ,an on-line measurement method can be adopted. Exploiting CCD imaging technology,laser spectrum comparing methodand energy spectrum of Fourier change ,an out of touch on-line image measurement is performed after a workpiece has been produced and the workpiece＇ surface roughness grade is exported soon. Increasing grinding surface roughness measurement efficiency,the method can realize on-line surface roughness measurement and an expected result also can be reached.
