    • A work piece 1 mounted on a movable table 22 is rotated while adjusting cutting depths of a grinding wheel 23 by means of feed motor so as to perform cylindrical grinding. During the cylindrical grinding, a thermocouple 42 is pushed to and caused to contact the rotating cylindrical grinding surface 1a of the work piece 1 at a constant pressure and thermoelectromotive force generated by the thermocouple 42 is measured. Surface roughness data corresponding to the measured thermoelectromotive force are obtained on the basis of the thermoelectromotive data obtained by the measurement and correlation between thermoelectromotive force and surface roughness concerning a known standard surface previously obtained and memorized. The surface roughness data are output and displayed on a display section. Therefore, an in-process measurement of surface state of the work piece 1 can be performed, while the machining such as cylindrical grinding is being carried out.
    • 通过进给电机调节安装在可动台22上的工件1,同时调整砂轮23的切削深度,以进行圆柱磨削。 在圆筒磨削过程中,热电偶42被推压并使其在恒定压力下接触工件1的旋转圆柱形磨削表面1a并测量由热电偶42产生的热电动势。 基于通过测量获得的热电动势数据和关于先前获得并记忆的已知标准表面的表面粗糙度之间的相关性的热电动势数据获得与所测量的热电动势相对应的表面粗糙度数据。 表面粗糙度数据被输出并显示在显示部分上。 因此,可以进行工件1的表面状态的过程中的测量,同时进行诸如圆柱磨削的加工。
