SURFACE ROUGHNESS MEASURING DEVICE, MEASUREMENT STAND-BY TIME SETTING METHOD, AND MEASUREMENT STAND-BY TIME SETTING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a surface roughness measuring device which allows measurement even for a section having a narrow measurement range while reducing measurement start time.;SOLUTION: Measurement data on displacement is acquired by scanning a test piece 80 by a pickup 16. The measurement begins immediately after a start of the travel of the pickup 16. The displacement measurement data acquired through the measurement is analyzed and a point from which a measured-value begins to become stable is detected as a measured-value stabilization starting point. A travel time required for the pickup 16 to reach the measured value stabilization starting point is obtained. The obtained transit time is set to be a measurement stand-by time.;COPYRIGHT: (C)2013,JPO&INPIT
