Studie ekonomiky technologie obrábění / The Study of Economics of Tooling Technology

Ondrášek, Dušan January 2008 (has links)
The aim of this diploma thesis addresses issues related to obtaining methodology for the production manager´s decision-making process in the field of technology selection, suitable tooling and cutting tools selection for a specific order or particular production plan. Evaluation of the manufacturing process while taking into consideration complexion of process controlling and contexture to the economy of this process. Analysis and evaluation of technological and economical aspects of a manufacturing process of the CNC chip machining in a real environment is targeted on the field of tooling, its selection, purchase, economy and consumption. The process controlling of technology is based on this analysis as well as the formulation of measuring by economic indicators such as economy, productivity, profitability etc. The analysis of important factors and parameters of this process demonstrated an influence on economy of the company. Several model cases have been created from the company records and from the provided research, the output of which became a basic methodology. The output of the analysis indicates possible directions of a management decision making. Thanks to a complex technical-economic view this thesis can serve as a methodological instrument for decision makers in the field of technology and cutting tool selections as well as an economy of production process improvement.

Technologické a ekonomické aspekty aplikace CNC obráběcích center / Technological and economical aspects aplication CNC machining centers

Martiňák, Marek January 2010 (has links)
The Aim of this diploma thesis has been to analyse the application of the CNC machining centers for the production especially with concentration on accuracy and economical aspect of the machining process. After the study of the literature and making familiar with the production on the CNC machine tool of the type Deco Sigma 20 ( manufacturer, the firm Tornos ) it has been evaluated the technology of the design of the chosen part, its machining accuracy and found out the economical parameters of this machinery for this chosen part as a necessary supposition for securing the correct production in accordance with the requirements of the client. The described process of the technological and economical preparation for the production as well as its checking can be used in future for the proposals of the further similar parts.

Možnosti systému Sinumerik při programování CNC obráběcích strojů / Sinumerik tools for programming of CNC machines

Kulenda, Martin January 2011 (has links)
The master’s thesis incorporates the control system Sinumerik 840D to the most widely used control systems of CNC machine tools. In the first thesis part are analyzed the NC programming methodics, which are relative only to the control system Sinumerik 840D and an essentials necessary to understand the issue in the area of CNC machine tools. Next part of the thesis includes design of the technology and processing of the NC program for machined component (gearbox cover). The NC program is made by ShopMill that is focused on a workshop area. During the program creation is combined a ShopMill and parametric programming, with using of a conditional jump instructions and repetitions. The final part of the thesis includes verification of the selected component production process by simulation and technical-economic evaluation of the designed technology.

Možnosti systému Sinumerik 840D při programování CNC obráběcích strojů / Sinumerik 840D tools for programming of CNC machines

Olina, Anna January 2012 (has links)
Master’s thesis presents the history and the present-day state of CNC machines and their control systems. This thesis describes both the basics and the advanced methods of programming which can provide the ability to create NC program for Sinumerik 840D to operate. The second part of the thesis deals with the development of the technology to machine the part (the frame of the reduction gear) and corresponding NC program. This program is created by means of the work-step programming (ShopMill). The final verification of the program was provided by means of simulation component of the control system.

Racionalizace technologie výroby / Rationalisation of production technology

Konečný, Petr January 2014 (has links)
This thesis deals with the rationalization of production technology of selected component. The first part contains a brief introduction of the company NTS Prometal Machining s.r.o. and brief description of the product. The following section is an analysis of existing manufacturing technology. The practical part is focusing on the proposal of rationalization versions of the production process. After evaluation of all possible options of rationalization there has been developed a new technological process with a respect to time and cost savings. Finally there was carried out economical evaluation and recommendation for further production of this component.

Manipulační nástrojová jednotka / Automatic Tool Changer

Láznička, Petr January 2015 (has links)
The thesis is focus on design solutions of automatic tool changer for CNC vertical milling machine SLV 300 in cooperation with the design company IMC/Engineering s. r. o. The main goal of theses is the creation of several design variants based on the critical research of similar machinery and the subsequent choice of the most appropriate solution. The assessment of the various options is done with amount of the changes caused on the existing design of the machine. It is essential the suitability of the solution from the perspective of the customer's company SolidVision s. r. o. Design solution is being designed for the possibility of a presentation device with unique features in its class, which is meant to be a simple maintenance free design with the possibility of easy service access For the chosen solution of the automatic tool changer are by calculation verified by the most exposed part of the device. In the thesis is also design documentation, for a better understand of the design solution.
