Analysis of NC programming options for enclosed pockets
Janda, Jiří ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
The aim of this paper is to provide an overview of the available strategies for milling of closed pockets. In particular, it focuses on advanced programming using CAM programs. In the next parts, the work is focused on the analysis of the force load of tools in the machining of the pockets. Here it focuses on the course of forces in milling at the corner of the pocket using different methods of analyzing this load. There are also ways to reduce this burden.
Design of Assistant Brake for Mechanical Wheelchair
Vaněk, Roman ; Osička, Karel (referee) ; Sedlák, Josef (advisor)
The goal of this diploma thesis was the design of an assistance brake for a mechanical invalid wheelchair. The theoretical part includes the sorting of wheelchairs and available technology of braking systems. In the practical part, there was prepared the design and testing of the assistance brake. In the final chapter, the technical-economic evaluation of the designed solution was discussed and compared with the existing technologies.

Furthermore I will hold a discussion about this topic and make a quick summary.
Ultrasonic machining technology
Chromý, Jakub ; Chladil, Josef (referee) ; Osička, Karel (advisor)
This bachelor thesis deals with a detailed analysis of the possibilities of using ultrasonic technology, introducing a basic theory of physical principle of ultrasound, using various non-destructive applications of ultrasound in engineering It also reviews ultrasonic machining technology and its possibilities at last but not the least.
Application of a measuring probes in milling proces on CNC machine MCV1210
Horáček, Kryštof ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
This diploma thesis focuses on the application of measuring probes in the machining process. The main goal of the thesis is to create sample procedures for measuring cycles and functions in a CNC machining process using MCV 1210 and selected measuring software. In the first part of the thesis available methods of machine measurement are outlined with a great emphasis on the description of measurement principles, construction, and measurement signal transmission methods between tool probes and the workpiece. The second part of the thesis deals with the application of measuring probes in the machining of the designed test piece using the Productivity+TM and Sinumerik ShopMill softwares. The work also includes an economic evaluation of the profit of an investment in the mentioned measuring equipment.
Assembling the Technological Process for a Part of the Gearbox

The thesis also deals with generating NC program, techno - economic comparisons, the design of worholding devices and recommends solutions of other identified issues.
Analyssis of unconventional technologies for sawing.
Šimek, Ondřej ; Osička, Karel (referee) ; Zemčík, Oskar (advisor)
The main theme of this work is a survey of contemporary knowledge in the area of unconventional technology of material cutting. Emphasis is placed on both - machines, tools, principles and parameters of each method - and comparation of all methods among each other and recommendation of these methods for practise.
Rationalizaton technology of production solid 14.037.270
Lačňák, Martin ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
This thesis deals with the rationalization of the existing body of machining 14,037,270 for five-axis CNC machine HERMLE C20U with Heidenhain control program. The work is focused mainly on streamlining the production of holes in the part. In the introduction technology is developed, which was created by Elakov. Based on analysis of existing housing production technology, new tools have been selected and designed a new technology. By consolidating all of the results efficient and economical production alternative was designed.
