An experimental research of the accuracy of overhauled valve seats with the variable cutting conditions

Abstract

One of the most important quality indicators in the valve seats overhauled process of the timing gear in the internal combustion engine is a parameter of deviation from roundness which is formed during their machining in a car repairing industry. In this work variation influence of the process conditions on the geometric precision valve seats during their formation was experimentally researched. According to the results of the ivestigation the rational cutting conditions were defined, that allows to provide a minimal deviation from the roundness of the valve seats.
