Technological, economical and ecological aspects of dry machining
Vostřel, Josef ; Csölle Putzová, Ildikó (referee) ; Píška, Miroslav (advisor)
Using of process liquids improves the procedure and results of machining, on the other hand, increases costs and raises some ecological and hygienic issues. In the work there is gradually analyzed mechanism of chip formation, progress and distribution of heat and thermal fields as well as economic and ecological aspects of dry machining and influence of dry machining on durability of tools. In the experimental part there are evaluated data which were measured during the drilling of cylindrical workpiece with regards to progress of workpiece thermal fields while using various kind of tool coating. In the final part there are stated recommendations for practice.

Modern cooling lubricant for metal machining
Nováček, Pavel ; Sámelová, Vendula (referee) ; Zemčík, Oskar (advisor)
This work covers the characteristics of different types of processing fluids used in machining; their types, the possible ways to supply and certain operational activities associated with the use of these liquids. The following are some of the modern trends in machining including dry machining, comparing their abilities with the machining process with fluids.

Production of an Injection Mold.
Jílek, Bohumil ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
This thesis is focused on a production of injection molds. It contains some analyses of the various parts of the injection molds, a description of their functions and the possibility of structural design. A summary of existing technologies for the production of these molds, their advantages and disadvantages is included. This thesis deals with design of the component parts for injection of plastics, strategy of machining and a simulation of machining.

Process fluids using during machining
Paučo, Jakub ; Kalivoda, Milan (referee) ; Gregor, Lukáš (advisor)
This bachelor thesis deals with the topic of process fluids used in machining. The first chapter deals with the cutting environment and the functions of process fluids. The second chapter describes the important properties of process fluids and the third chapter describes the various types of fluids and other methods of cooling and lubrication of machining processes. The fourth chapter discusses the use of process fluids in specific machining methods. This involves drilling deep holes and grinding. The following fifth chapter describes dry machining and all its methods. The sixth chapter is devoted to the impact of process fluids on the environment and also lists ecological alternatives to the conventional method of cooling and lubrication of the machining process, such as the use of vegetable oils or the MQL/MQCL method. The last seventh chapter contains a comparison of dry machining and the MQL / MQCL method, as well as an evaluation of future developments in the field of process fluids.
