Evaluation, Revision and Application of the Nbs Stylus/Computer System for the Measurement of Surface Roughness (Classic Reprint) - Brossura
Sinossi
Excerpt from Evaluation, Revision and Application of the Nbs Stylus/Computer System for the Measurement of Surface Roughness
At a particular point in the stroke, the stylus arm activates a relay, which in turn generates two pulses. The first pulse, one second long, appears at the common input of the recorder and interface amplifier. (the source of the. Event pulse is in the information channel only for the duration of the pulse). Coincident with the leading edge of the event pulse is a fiftyemicrosecond interrupt pulse to the a/d converter. On receipt of the interrupt at the a/d, a programmed one - second delay is executed, and the analog signal at the filter output is convertedf to binary data points and stored sequentially in computer memory. (thus the event mark, recorded on the strip chart, does not appear in the digital data.)

Paperback. Condizione: New. Print on Demand. This book details a comprehensive system for the accurate measurement of surface roughness using a stylus instrument and minicomputer. The author describes a step-by-step process for calibrating the system using an interferometrically measured step, and for calculating important characterizations of surface profiles. These characterizations include the arithmetic average value, the mean square value, the amplitude density function, the autocorrelation function, the average wavelength, the average slope, the skewness, and the kurtosis. The author also includes a statistical evaluation, using empirical and analytical techniques, of the calibration procedure's long-term stability. The significance of this book lies in its contribution to the study of surface roughness. It provides a valuable resource for researchers and practitioners in the field, offering a comprehensive and reliable method for characterizing surface topography. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Codice articolo 9780428088521_0
