Reglering av matarsystem vid höghastighetskapning

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great Manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

Förbättringsarbete mot Lean Production på Tooling Support Halmstad AB

Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.

Utveckling av snabbfäste och verktyg för byte av sågklinga

This thesis is based upon the work done at Westinghouse electric company (WEC)inVästerås during the spring semester of 2015 and describes the development of a quickcoupler with associated blade changing tool. These are meant to be used togetherwith a sawing tool that the company uses for the dismantling of nuclear reactors,which is performed under water.The aim of the thesis was to develop a complete Manufacturing documentation withdrawings and related CAD models which Westinghouse later can use to manufacturethe tool and the quick coupler. It was also included in the assignment to, if necessary,modify parts of the saw tool to adapt these to the intended blade changing tool.A number of visits to the company's workshop was made during the time to study thesaw that the thesis is based upon. The purpose of these visits was to get a better ideaof the dimensions, construction and the field of use of the saw. On three of thoseoccasions various engineers and consultants accompanied us to discuss possibleproblems with different ideas.This was interspersed with information in the form of literature studies on quickcouplers to create a clearer picture of the nature of the task.When enough information had been gathered a functional analysis was made to dividethe main problem into subthis phase the idea and concept generating process took place.The methods used for this was mainly brain writing and brainstorming.

Besparingsmodell för produktivitetshöjande arbete inom skärande bearbetningsteknik

The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.

Made by China : Outsourcing av Konstruktionsarbete till Kina

Outsourcing means to contract out work previously done within the cooperation to a supplier.This is an increasing trend today. Traditionally companies have outsourced Manufacturing butwith the growing specialization they tend to outsource other activities as well.China?s economical reforms and entrance into the World Trade Organization, WTO, hasenabled international business connections. Since China offers one of the cheapest labours inthe world, many companies have an interest in starting up an activity in the country. Themany foreign investments in China have lead to an economical growth which in turn hasmade it possible for China to invest in the Chinese competence and innovative capacity.The commissioner of this master thesis, SMS, is one of the leading actors in retrieval ofamong other things mounts and stands for flat screens and projectors.

Flygteknik : Konceptstudie av ett obemannat flygplan

Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning

The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized Manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.

Dutch Disease and Tourism - The Case of Thailand

Tourism is often being viewed as one of the worlds largest sectors and a great contribution to growth and development. There is a large motivation amongst developing countries to promote themselves as a tourist destination, since they expect the tourism to generate economic growth. The government of Thailand has been promoting tourism since 1960, and the number of foreign visitors has increased from 100 000 back then to 13.5 million in 2006. The purpose of this paper was to investigate weather the increasing tourism industry in Thailand has pulled resources away from other sectors of the economy towards the tourism sector, and in that way harming Thailand?s international competitiveness and causing deindustrialization.

Analys av verkstadsplaneringen : på Fläkt Woods i Jönköping

This paper is finishing part of the two-year master programme in Industrial Engineering and Management.Initially there was an inquiry of studying the queue-times that Fläkt Woods uses when they break down internal working orders. These times were assumed to be too generalised and does not apply to the actual value of the queue-times which generates incorrect data and delivery delays. During the work of this paper it has been established that it is not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of Manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems.

Resurssnåla materialflöden - En fallstudie på Volvo Powertrain

From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within Manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.

Optimering av smidesgeometri för P-fläns på bakre turbinstativ (TEC)

This thesis work has been performed at Volvo Aero Corporation in Trollhättan, at the department of ?hot structures? involving aircraft engine GP7000. The purpose with the study was to investigate the possibility to reduce size of the forging of flanges on the rear turbine frame when purchasing. Thereto examine the parameters that affect the flanges motion during the Manufacturing process. The goal was to provide Volvo Aero with foundation to later bring in slimmed forgings.

Fallstudie av produktionschefers ledarskap

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from Manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the Manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
