Použití měřících sond (nástrojové a obrobkové) pro stroje z produkce TOS KUŘIM / Using measuring probes ( for tools and workpieces) for production machine of range of products firm TOS KUŘIM

Kohút, Josef January 2011 (has links)
The purpose of this dissertation is to familiarize the reader with basic recognition of machine measuring probes for tools and workpieces. Namely then in area of measurement on CNC machining centers. Both recognition from aspects of principle of function of sensing elements and type of transmition to control system, and recognition from constructional aspects are described here. Further it puts mind on equipment of machine probes (touches etc.) and rules for best selection of this equipment. Next part of this work describes selection of appropriate probes, for universal machines from production of firm TOS Kuřim. Last part deals with testing of designed measuring system for concrete machine from production of firm TOS Kuřim. His typical composition, evaluation of tests results and achieved accuracy is also described here.

Multifunkční obráběcí centrum pro rotační i nerotační obrobky / Multifunctional machining centers for machining rotating and prismatic parts

Grätz, Tomáš January 2014 (has links)
In this master's thesis is elaborated lay-out, calculations and technical drawings to multi-function machining center. Here is applied solution with vertical carousel combined together with the upper gantry milling machine. The aim of my work is to design a compact milling ram allowing turning and milling in deep slots or next to the tall walls of the workpiece. Furthermore here is elaborated lay-out of automatic tool change with magazine and lay-out of clamping exchangeable milling heads. Emphasis is placed on the manufacturability and reliability of the whole structure.

Konstrukčně-výrobní řešení upínacího přípravku / Construction and Manufacture of a Clamping Device

Okáč, Petr January 2014 (has links)
The thesis deals with various aspects of the structure - manufacturing solutions fixture in terms of small manufacturing firm. In the thesis are discussed problems which the author of the thesis with small-scale production meets. A substantial part of the thesis is also made by comparation of the production of small series production and large series. Emphasis is placed on efficiency and economy of the entire production process.

Racionalizace výroby skříní / Rationalization of production casing

Konečný, Jan January 2015 (has links)
The thesis deals with the reorganization of production injection pump casing, when the existing production solution, using cutting lines, did not meet the requirements for flexible manufacturing. There are handled points leading to the replacement of the line of machining centres after a brief introduction of the company. Among the main points of thesis are the design of operations, choice of tools and cutting conditions, proposal clamping device and technology, techno-economic evaluation of the newly introduced production.

Výpočtová analýza stojanu pro horizontální vyvrtávací centrum / Computational analysis of column for horizontal boring centre

Fargač, Michal January 2016 (has links)
The theoretical study of this thesis deals with different approaches that can be used to optimize the topology of various structures. Main attributes and principles which they are based on of individual methods are discussed. The first point of the practical part is to design the model for computational analysis of stand and other machining centre parts based on real machine TOS FU. Afterwards, the model is analyzed to determine the dynamic characteristic of the machine. Subsequently, several changes of the stand design are performed in order to improve the dynamic behavior. Eventually, new stand kernel is designed which aims to enhance these dynamic characteristic. This model is analyzed again and the results are compared with the original form of the machining centre.

SYSTÉMOVÝ PŘÍSTUP PŘI NÁVRHU OBRÁBĚCÍCH STROJŮ / SYSTEM APPROACH OF MACHINE TOOL DEVELOPMENT

Dosedla, Michal January 2012 (has links)
The doctoral thesis deals with a position of a design process in machine tool life-cycle and with main design approaches. Main aim of the doctoral thesis is to bring System approach of machine tool development. This method follows design team experience with support by systematic methods and managing by product manager. Alongside this method respects System approach defined by Janicek. It is possible to achieve increasing of machine technical quality, reducing of final machine costs and reducing of time for machine tool creation by application of this method. System approach of machine tool development is focused on detailed outer and inner optimization of a machine structure from technical and economical point of view. This design approach is possible to apply in any production company because it is brought in intelligible way.

Využití technologie virtuální reality k monitoringu a vizualizaci vybraných provozních vlastností stroje a jejich analýze / Use of Virtual Reality Technology for Monitoring and Visualization of Selected Operational Charakteristics of Machines and Their Analysis

Augste, Jan January 2017 (has links)
This dissertation deals with the study of the use of virtual technologies for an analysis of operating characteristics of a machine. Operating characteristics of a machine are parameters that determine the usability of the machine to accomplish a certain task in addition to the specified time and under the certain conditions. These include parameters that can be changed based on customer requirements, for example, the table size and the highest spindle speed to the parameters influenced from the start of the machine design such as positioning accuracy, acceleration value in the axes or consumption. The first part sets out general requirements for visualization of information and these are subsequently verified experimentally in the chapter devoted to the time visualization protocol. This thesis presents the original experiments to determine the basic requirements for visualization of a measured quantity, in this case the feed rate. By verifying usability when displaying these properties on the underlying data showing machine position change, the four basic requirements for visual data processing using immerse virtual reality are validated. A deeper insight into the work with data will enable to analyse more complicated relations within a longer period, greater transparency and clearer outputs of analysis.
