Abstract

PURPOSE:To detect maximum height and ten-point roughness automatically by detecting the positive and negative peaks of a displacement signal from a surface roughness displacement gauge and by processing them. CONSTITUTION:The positive and negative peaks of a displacement signal from surface roughness displacement gauge 1 are detected by positive-peak detector 11 and negative-peak detector 12, and positive and negative peak signals are inputted to comparing arithmetic circuits 31 and 32 to find required data from the maximum to 3rd ones successively. The required data from comparing arithmetic circuit 31 and 32 are stored in memory circuits 41 and 42 while updated at any time. The memory data of those memory circuits 41 and 42 are inputted to subtracting circuits 51 and 52 to find the maximum height and ten-point mean roughness of the surface roughness.
