Vliv technologie krátkých přerušovaných řezů při soustružení na trvanlivost břitu

Abstract

This bachelor’s thesis focuses on the influence of short interrupted cutting technology on the tool life of indexable inserts during turning. The theoretical part covers the basic concepts related to turning, cutting tools, their wear, and factors affecting tool life. The experimental section is dedicated to the development and optimization of a methodology for wear testing in interrupted machining of stainless steel. Initial tests revealed issues with undesirable forms of wear, which led to adjustments in the methodology and chip breaker selection. A final testing methodology was developed, enabling reliable monitoring and evaluation of tool life. Based on the experimental results, the characteristics of wear were analyzed and the tool life of two insert samples was compared. The final methodology provided representative data on tool life and the variability of wear observed under the given interrupted cutting conditions.
