Tool wear testing method of cutting tools with cermet cutting edges in turning
Koppová, Aneta ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The diploma thesis deals with the analysis of the wear of tools fitted with cermet cutting edge. The first part is focused on the theoretical aspects of the problem, which are applied in the practical part. The aim was to perform cutting tests in which carbon steel was turned under selected cutting conditions. Tool wear during turning and the quality of the machined surface were monitored. Machining continued until the selected wear criterion reached the limit value. Two different cermets were tested and the measured data were the basis for the analysis of the wear of the tool edges and the determination of the tool life.

The bachelor thesis is focused on monitoring production machines efficiency in the Siemens s. r. o., o. z. Elektromotory Mohelnice company via the Overall equipment effectiveness indicator. The aim of the work was to analyze the current state of machine monitoring, to evaluate existing solutions, and to propose further development options. The analysis of the current state contains a description of the data collection method used, an evaluation of the data, and a visualization of the results. The information served as a basis for determining a scheme according to which the company will focus on the most important machines and draw up an action plan in order to reduce downtime and, consequently, increase production productivity.
