| 1 | Self-calibration and Compensation of Setting Errors for Surface Profile Measurement of a Microstructured Roll Workpiece显示文摘Microstructured roll workpieces have been widely used as functional components in the precision industries.Current researches on quality control have focused on surface profile measurement of microstructured roll workpieces,and types of measurement systems and measurement methods have been developed.However,low measurement efficiency and low measurement accuracy caused by setting errors are the common disadvantages for surface profile measurement of microstructured roll workpieces.In order to shorten the measurement time and enhance the measurement accuracy,a method for self-calibration and compensation of setting errors is proposed for surface profile measurement of microstructured roll workpieces.A measurement system is constructed for the measurement,in which a precision spindle is employed to rotate the roll workpiece and an air-bearing displacement sensor with a micro-stylus probe is employed to scan the microstructured surface of the roll workpiece.The resolution of the displacement sensor is0.14 nm and that of the rotary encoder of the spindle was 0.15.Geometrical and mathematical models are established for analyzing the influences of the setting errors of the roll workpiece and the displacement sensor with respect to the axis of the spindle,including the eccentric error of the roll workpiece,the offset error of the sensor axis and the zero point error of the sensor output.Measurement experiments are carried out on a roll workpiece on which periodic microstructures are a period of 133μm along the circumferential direction.Experimental results demonstrate the feasibility of the self-compensation method.The proposed method can be used to detect and compensate the setting errors without using any additional accurate artifact. | GAO Wei XU Bin TAKEISHI Toshiki SHIMIZU Yuki ITO So | 2014 | Chinese Journal of Mechanical Engineering2014，27，1： | 3 |

| 9 | Design and Development of Oblique-Incident Interferometer for Form Measurement of Hand-Scraped Surfaces显示文摘Precision flat surfaces finished by hand-scraping are extensively used in the sliding parts of precision positioning systems or the surface plates of precision measuring instruments.These hand-scraped surfaces are employed to improve the flatness of the machined surfaces and the motion accuracy of the instruments.The numerous depressions of micrometer-scale depth on a scraped surface are thought to prevent wringing and improve the lubrication properties by forming oil pockets.Form measurement of the micrometer-scale features of a hand-scraped surface is one of the reasonable methods for investigating its effect on the motion accuracy of the positioning systems or the lubrication properties of the sliding parts.Because a hand-scraped surface is a rough surface composed of micrometric complex features,it is difficult to conduct precision measurement of the three-dimensional surface form using conventional measurement instruments,such as vertical-incident interferometers or stylus-type profilometers.In this study,an oblique-incident interferometer based on Abramson interferometry is introduced to measure the form of a rough surface produced by hand-scraping.Because this technique can detect high-intensity reflected light on a rough surface,it allows the measurement of the form of the hand-scraped surface in noncontact condition.In order to shorten the measurement time,the form calculation based on a five-step phase shifting method was introduced. | So Ito Daiki Kameoka Kimihisa Matsumoto Kazuhide Kamiya | 2021 | Nanomanufacturing and Metrology2021，4，2： | 0 |
