Evaluation of accuracy of in-process gauging of diameters by rolling method

Abstract

A scheme for in-process diameter gauging by a metering-disk rolling method is considered. The systematic-error components of in-process diameter gauging in cylindrical-surface processing on a lathe are described.Instruments and systems for in-process gauging using a metering-disk (MD) rolling method are widely used in various branches of industry. We shall review only a few of the studies of MD in-process gauging.The in-process gauging system developed at the Kramatorsk Scientific-Research Institute of Rolling Machines and Lathes [1] for sheet cutting as well as systems for coiling sheets on reels [2] and automatic correction of the positions of elevator compartments in tall buildings [3] have proven to be effective. The rolling method is appropriate for in-process gauging of sheet thickness by controlling the distance between the rollers [3]. At the Ukraine Scientific Center (Kiev), on the basis of [4], a device was proposed for in-process monitoring of the application of scales on tape measures. Instruments with MD in-process gauging for lathes have been developed at the Krasnoyarsk Agricultural Institute [5]. Similar work has been performed at the Leningrad Polytechnic Institute [6].last revolution, data on the specified diameter of the MO are sent from a logistics device 7 to bidirectional counter 14. The diameter is measured in the next several revolutions of the MO. Then, in the next revolution of the MO, the difference between the

“…Some of the contact measuring methods, especially friction-roller methods [4,5] are still used to measure large-scale diameter workpieces. However, there are several disadvantages arising from the contact measurement where scratches, chips, etc., could damage the sensing part of sensors.…”

“…Mechanical method is one of the contact techniques. The friction-roller type instrument [4,5] and the calliper-type method are some examples of the mechanical methods applied to measure the diameter of a workpiece in in-process measurement. Although the accuracy of the friction-roller type and the calliper-type method are not high enough, they have been widely used to measure large-scale diameter workpieces.…”
