Vliv nástroje na řezné odpory při CNC frézování
Nesázal, Petr
The master thesis is focused on measuring of cutting forces and milling on the CNC machine SCM Tech 99 L when MDF (Medium Density Fibreboard) is used as the machined material. The dynamometer Kistler 9257 B and DynoWare software is used for the measurement of forces and data analysis. The theoretical part of the thesis relates to the characteristics of the CNC machine, tools, tool angles and the methods of cutting resistance. The experimental part provides the description of the experiment itself as well as the changes of cutting conditions during the experimental process when using certain tools. Moreover, it explains the procedure of data processing and shows its final results. The conclusion of the thesis evaluates the data of cutting forces and cutting resistance. These data are further compared based on the technology and the parameters.

The bachelor thesis is focused on milling on the CNC machine. The first part of the thesis deals with the theoretical overview regarding the topic. It provides the description of the CNC machine parts, the characteristics of mills and the milling technology. The following part focuses on cutting conditions during the experimental process and the procedure of data processing is also described in this part. At the end of the thesis cutting resistance data of the machined MDF (Medium Density Fibreboard) sample are evaluated. These data were recorded by the Kistler dynamometer and further used to ascertain the resultant force.
