The diploma thesis deals with the influences on business planning, to which companies adapt in effort to succeed in a dynamic production and market environment. The influencing effect causing changes in the production company and the ability to react flexibly can eliminate possible losses or outages in production. However, adaptation leads to significant interventions throughout the company's value chain. The theoretical part presents the possibilities of business planning, which can have a significantly useful impact on management of the order across the pre-production and production stages. In the practical part, simulation models are demonstrated proofing nagative influencing effects. Then the methodology is compiled, witch leads the future user, how to limit or eliminate both internal and external disturbing effects.

Diploma thesis deals with a topic of lubrication and cooling of the ball screw rotary nuts. The first part is focused on a research behind the theory of ball screws and ball screw rotary-nuts. The three types of construction were developed in the second half of the thesis. Each construction is designed as an external attachable cooling and lubrication unit, which can be installed on an existing, slightly modified ball screw rotary-nut. For cooling and lubrication, only one type of medium is used and that is a cooled oil. External unit provides medium flow to ball screws working space. On top of diploma thesis tasks a design concept of ball screw rotary-nut with an integrated cooling and lubrication is introduced itself. Both described designs could become interesting for an industrial market.

The research part describes the basic principles of predictive maintenance methodology and virtual twin technology. The practical part includes a simplification of the initial cross table model. This model was then transferred to the simulation software MSC Adams, where it was optimized so that its behavior corresponds as closely as possible to the physical device. Several simulations were subsequently performed on the model. Then a concept for a predictive method for calculating the remaining service life of individual sections of the ball screw was presented. Simulations performed on a virtual twin served as a source of data to test the proposed method.

The topic of this work is the design of a small model CNC milling machine with a fixed table for machining wood, plastic, or light alloys (Al, Zn, etc.). It also includes a calculation report and drawing documentation of selected nodes. The beginning of this work consists of an introduction to the issue of milling machines, their distribution and subsequent market analysis. Subsequently, the input parameters are designed on the basis of market analysis and in the last part there is a calculation report, the design of the milling machine itself and a short economic evaluation.

This diploma thesis deals with the design the drive of the feed coordinate portal machining center using a gear rack and pinion. The thesis contains researches from the area of CNC machining centers for non-rotating parts and sliding linear systems. Market analysis of portal machining centers of type of lower gantry with a gear rack and pinion was done. Furthermore, several design variants are proposed in terms of positioning the drive on the machine. These variants were further compared and the best option was selected for the specified machine. Subsequently, the technical calculation of the drive is performed and individual parameters and structural elements are proposed. The thesis also includes a 3D model of the proposed variant and the required drawing documentation.

This diploma thesis deals with the design of a two-axis multi-spindle lathe carriage. In the first part, there is made a research, and its aim is to find possible variants of design solutions. After the best rated variant was selected, the thesis further continues with the necessary technical calculations of the main design nodes such as a synchronous servomotor, ball screw, linear guide and bearing. The design itself was carried out with regard to calculations and the resulting model was examined in terms of dynamic stability. The subject of examination was to find the natural frequencies of the assembly and to determine the amplitudes of the oscillations which arise from the harmonic excitation force. Finally, Lobe diagrams for grooving and longitudinal turning operations were drawn.

The content of this thesis is the description the various component of the linear feed axis, which are used in heavy duty machine tools. This describes their features, advantages and disadvantages and on these basics, are selected different appropriate design variants. In the second part of this thesis has been drawn up constructional design of these variants. They were subsequently compared and then was chosen the most ideal one for the designed machine, which is heavy machine tool upper gantry type. The work also includes the 3D CAD model of the final version and drawing documentation.

This diploma thesis deals with the design of linear axis for heavy machine tool. The thesis describes the definition of heavy machine tool and its basic construction nodes. The next chapter describes the components of the linear feed assemblages, the basic principles of use and their advantages and disadvantages. On the basis of this research part there are selected variants of the solution and in the last part of the thesis there is a design of the axis X of the gantry machine tool. Part of the work is a 3D model of the proposed feed assemblages and part of the drawing documentation.
