The thesis presents the formation and influence of thermal loads on cutting tools during turning. The latter have a great influence on the correct selection of process parameters, and thus achieve the desired productivity, surface integrity and durability of the tool. In order to manage these conditions, it is important to provide an appropriate process for monitoring the development of the temperature in the cutting zone. Current procedures, which are mostly based on the use of resistance temperature sensors, are problematic from the point of view of measurement repeatability.
With the goal of monitoring the development of thermal loads, we designed a measuring system in the Cutting Laboratory that monitors the highest temperature on the cutting tool for turning using a pyrometer during cutting. With the help of the developed system, we will be able to have greater measurement reproducibility, a better view of the adequacy of processing parameters, cutting tool material and the effectiveness of cooling and lubrication approaches.
We then tested the measuring system and found that it is capable of measuring the temperature correctly. Namely, we obtained measurement temperatures that are comparable to other measurement methods.
