Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This article presents the results of the study of micro-hardness on the end surface along the involute tooth profile after processing with a rolling tool.The results of the study showed that the value of micro hardness obtained by processing with "shaver-rolling device" made of steel R6M5 is obtained within HB 263-271, and when processed with using "shaver-rolling device" made of ShH15 steel within HB 274-276.The results of experimental studies have shown that with an increase in cutting speed, the micro-hardness of the side and main working surfaces of the teeth wheel decreases.The most favorable results were obtained when processing tools is made of steel ShH15 at cutting conditions: n = 100-400 rpm; S = 0.2 mm/rotation.
