This thesis will address the design and production of the ATC Kolín comapny's logo. Thesis will be supported by the use of CAD/CAM programs. The choice of materials, components and tools will also be specified. Milling strategy will be designed with the PowerMill program. Two different methods of production will be compared. First one is the conventional machining on the FV 25 CNC vertical knee milling plant with the Heidenhain iTNC 530 controlling system. Where as the second one is the additive rapid prototypong technology with the usage of Fused Deposition Modeling method. The thesis is finished by the technical-economic evaluation with analysis and comparison of production alternatives.

The diploma thesis contains the manufacturing process of ingot mold part for pistons manufactured by gravity casting using FeatureCAM software. It deals with the selection of appropriate machinery and tooling, determining the cutting conditions and the solution selection of optimal machining strategies in FeatureCAM software. The whole machining process is verified by graphic simulation and is completed with drawing documentation of component.

This master's thesis deals with design and manufacture of a prototype of pitman front right wheel of student's formula Dragon 4 of a team TU Brno Racing with use of advanced CAD/CAM technology. Opening part of the thesis deals with the theoretical analysis of milling technology. Furthermore, there is an analysis of aluminum alloys, which aims to integrate the material being machined CERTAL. In the practical part of the work the construction of pitman is done using CAD software SolidWorks 2012 and proposal of milling strategies is done using software PowerMILL CAM 10. The following is the realization of manufacture in CNC machining center MCV 754 QUICK at Bosch Diesel Ltd, in Jihlava. Techno-economic evaluation of the manufacture is done in conclusion.

The present master thesis deals with the application of workshop programming and advanced CAD / CAM technology to the design and production of differential holder and eccentric of Formula Student car. The first part characterizes and describes the technology of milling, drilling and boring. There is also a selection of material to be machined, including the characteristics of aluminium and its alloys. The following section describes the construction of differential holder and eccentric in the parametric program Autodesk Inventor and creation of CNC programs using the workshop programming and CAM of PowerMILL system. The conclusion section refers to the production of both components in the training centre BOSCH DIESEL s.r.o in Jihlava. The thesis is concluded with a technical-economic evaluation and analysis of both proposed production variants.

PURPOSE: To analyze surface roughness, the edge chipping of different CAD/CAM bur milled dental materials (bar and crown design of 1.0mm and 1.5mm thickness), correlate the effect of machining damage on the material strength, compare the flexural strength of bur milled versus sectioned CAD/CAM blocks and evaluate the tool wear after milling. MATERIALS AND METHODS: Five dental CAD/CAM materials were used: Lithium disilicate glass-ceramic (IPS e.max CAD), Leucite-reinforced glass-ceramic (IPS Empress CAD), Feldspathic porcelain (Vitablocs Mark II), Feldspar ceramic-polymer infiltrated (Enamic), and composite resin (Lava Ultimate). Ten rectangular bars with dimensions of 4 mm × 2 mm × 14 mm were milled using a new set of burs for each material. Then, ten crowns of each material with thicknesses of 1.0 mm and 1.5 mm were milled after scanning a standard aluminum die with corresponding marginal thickness. The bars surface roughness was measured. Then, three specimens were selected for the edge chipping analysis using (SEM). Thereafter, 3-point bend test was used to test the flexural strength of bur milled and saw cut bars with the same dimensions. For the crowns, load to failure test was used. One-way ANOVA and Tukey HSD post hoc tests to determine the difference between the groups using JMP13.0 with α=0.05. RESULTS AND CONCLUSIONS: The surface roughness and edge chipping was significantly affected by the material composition. Comparison of the flexural strength of bur milled to sectioned bars, IPS e.max CAD and IPS Empress CAD show statistically significant less flexural strength (p<0.001). A strong correlation was found between the decrease in flexural strength and the chipping length on the central tensile side of the bur milled materials (R2=0.62, p=0.01). Crown thickness significantly affects the edge chipping as 1.5 mm crown thickness has more edge chipping than 1.0 mm crowns. However, no correlation is found between the load to failure test for the crown design and the edge chipping for 1.5mm and 1.0 mm thickness crowns. Tool wear is significantly affected by the material type. / 2021-07-31

Malongen consists of two volumes containing housing, a gallery, and a restaurant. The design language of the base comes from a 3D scan of the rock 30 meters north of the plot. The buildings are a design interaction to explore the tension between the historical mountain cut and a design interaction. With a digital imitation of the rock the buildings intend to mimic the surrounding area. The rock, that is the historical imprint of the place, is now translated into buildingelements, as a result of my manipulation of the file. This project has investigated how we can create a contemporary buidling that refer to a historical site and keep telling a story about time.
