Zefektivnění výroby statoru pro LCV 20 pomocí CNC horizontální vyvrtávačky ŠKODA FCW 150. / Improvement of the LCV 20 Stator Manufacture with The CNC Horizontal Boring Machine ŠKODA FCW 150.

Mejzešová, Monika January 2009 (has links)
This diploma thesis deals with a production process cast body of the stator the in the company Papcel, a.s., Litovel. The first part is focused on the description of the current production process. The production is realized with several manufacturing machines and hand machining also. The second part analyzes available changes of the current technology and describes alternative procedures and production facilities. The CNC machine-tool ŠKODA FCW 150 seems to be the most effective way of production, which could increase the labor productivity, cut the share of manual works, reduce a risk of a human error and to increase the final product quality and accuracy. The final part of the thesis evaluates the machine and preparation times for a single production, including assembly operations and financial impacts of the investments on the company costs.

Komplexní využití konstrukčních podkladů pro CNC programování turbínových skříní. / Total usage of design dates for CNC programming of turbine casing

Matejková, Monika January 2010 (has links)
This thesis aims at designing a solution to the comprehensive use of construction underlying documents for the CNC programming of turbine casings. The introductory part of the thesis contains a description of the CNC programming and CAD/CAM systems. The following is mapping of the current state of the construction underlying documents, and mapping of the situation in the department of technology in Siemens Industrial Turbomachinery, s.r.o., Brno. The further section presents an analysis of the problem that arose when processing and sharing the construction underlying documents with the aim of streamlining the CNC programming process. The closing part presents the evaluation and conclusions for implementation of the proposed solutions.

Technologie výroby vymezovací podložky / Manufacturing technology of the distance washer

Dvořák, Jiří January 2011 (has links)
This master’s thesis has been elaborated as a part of master’s studies of engineering technology M2I-K, major in M-STM – Engineering technology and industrial management and deals with the problem of a transition to a self-production of previously purchased distance washers. Distance washers were purchased in six different types of similar shape, each type in four different thicknesses. One of these types was chosen as a representative for this master’s thesis. We shall explore the possibilities of self-production with the emphasis on economical validation of the transition. The distance washer is a flat part, the intermediate being sheet metal. Technologies considered for manufacturing the washers correspond to the technical facilities and equipment available at the production hall of the company this project is planned for. The company possesses technology for CO2 laser cutting, cutting by CNC punching machine and cutting in the punching tool. To provide a complex overview we shall also enquire into cooperated technologies such as water jet and plasma cutting, oxy-acetyleny cutting and CNC working. All options are evaluated with regard to the production expenses and lead to a most economically plausible method of manufacturing or, if need be, give reasons for going back to purchasing the part from the current supplier.
