The aim of this diploma thesis is to design a single-purpose machine for machining steering wheel lever from PUR. The problem with the current state was the need of manpower for machine a large number of levers. The automated machining process eliminates the problem. The result of the work is a detailed 3D model of a single-purpose machine created in the Onshape program, drawing documentation of several parts of the equipment, economic evaluation and risk analysis of the machine. The conclusion of the thesis contains an evaluation of the whole project.

This thesis deals with the efficiency improvement proposal of production of engineering component for agricultural machine. Firstly, the current production proces is described including description of the component and determination of manufacture times. The next part contains efficiency improvement proposal of production including determination of manufacture times. The last chapter contains a comparison of both variants in terms of production costs. The final provision summarizes results which were achieved and overall benefits of the thesis.

To improve the geometric accuracy of CNC machined parts, dynamic machining errors due to on-line disturbances (tool deflection, tool wear, heat deformation, etc.) should be accounted for in some manner. Unless these on-line disturbances are properly handled, it is obvious that a high degree of geometric accuracy is difficult to achieve. Many attempts have been made to compensate for these on-line disturbances such as the development of engineering models; however, the models are not adequate enough for reflecting the real phenomenon and are dependent on continuous process monitoring using a variety of sensors. Closed-loop process control is a scheme for manufacturing parts and compensating for on-line disturbances and machine tool inaccuracies using error feedback. The goal has been to develop a system that automatically provides dimensional error feedback to the process machine. Closed-loop process control can be achieved before, during (in-process) or after the machining cycle. In-process control is achieved by measuring the part prior to finishing cuts while the part is fixtured to the machine tool. Although the theory behind an automated closed-loop, in-process control system would significantly reduce manufacturing costs, at the present time, machining errors typically are compensated through manual error feedback. This thesis presents a systematic approach for automatically compensating for dynamic machining errors based on a new closed-looped machining scheme. The new scheme incorporates these errors, found through in-process inspection, into a modified CAD model or "Variational Part Model". As a result, the Variational Part Model inherently contains the online disturbances associated with machining. It is important to note that this new scheme assumes the machine tool's static error (ball screw error, joint misalignment, perpendicularity error, etc.) has been addressed by some other compensating method and this scheme only addresses the dynamic machining error. To create the Variational Part Model, the machined part is measured on the machine and compared to the CAD model's theoretical data. The data is then used in conjunction with modeling functions contained in NX's Application Programming Interface (API) to interact with the CAD model and modify its feature geometry. The validity and effectiveness of the methods are presented as well as results from experimental testing. This thesis also presents the methods necessary for automatic CAM process updating to ultimately close the loop between machining and inspection.

This diploma is focused on analyse existing method usable for detection surface defects of grindling surface. Also suggests and practically testing new method for detection surface defects of grindling surface

Contactless measuring of surface temperature integration in the other measurement methods and their assimilation at evaluation of surface temperature of a semi-finished product bored by various tools is the target of the work. An impassable opening is being bored by these tools. The opening is close to a scanned wall. The semi-finished wall temperatures are being scanned by thermocamera and subsequently compared for every single used tool in this experiment.

The Thesis described within the scope of the Master Program is focused on cermets, which belong among cutting materials. The introductory portion of the Thesis presents the characteristics of cermets from the perspective of production, physical-mechanical characteristics, marking and usage in cutting. The core portion of the Thesis focuses on the role of cermets in the category of leading world producers of tools and instrumental materials, cutting evaluation, and the suggested working conditions of cermets in lathing operations. The working conditions are prepared for steel and cast iron. The conclusion of the Thesis focuses on a technical-economical analysis of cermets.
