In this report, frequency analysis on some lapped surface roughness are made. The profiles of turning specimens recorded on a magnetic tape are obtained using the stereo type pick-up which is rewired so as to measure the vertical displacement of its stylus.<BR>The conclusions obtained are as follows;……<BR>1) When logarithmic plot of frequency is taken on the axis of abscissa, frequency analysis curves of lapped surface roughness, that are called spectrum curves, show the Gaussian distribution approximately.<BR>This fact concurs with some results of other investigations on periodicity of lapped surface roughness<BR>2) The frequency corresponding to the peak position of Gaussian curves is considered to be the mean frequency.<BR>3) A constant functional relation between the output voltage at the mean frequency and the center line average roughness is derived.
