During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.

In the town of Väderstad which lies in the middle of Sweden, called Östergötland is Väderstad-Verken situated. It´s an international company which produce machines for land processing and sown to farmers all over the world. Väderstad-Verken is an expansive company with 750 employees. The turnover is 1.4 billion sek. Rapid seed-sower has become a popular machine since it was introduced in 1991.

The purpose with this bachelor thesis is to identify risks and insufficiencies concerning the production at WilloMaskin AB. The project is limited to only 4 machines, where theories as ?OEE? (overall equipment efficacy) should be illuminated and analyzed. The theory of ?Single Minute Exchange of Die? is also presented.The method used in this project is mostly based on qualitative studies but also quantitative studies are presented.

This study is preformed at Westbaltic Components placed in Töcksfors Sweden. Themain target in this study is to make one of the company?s assembly lines better andmore effective. The assembly line constructs vending machines for different stores allover Europe.It will contain tobacco, snuff, cigarettes and shaving blades and many more similarproducts.The first step in our study is to locate the daily problems and find out a good way toreduce them and make them disappear. A good way to do this job easier was toconstruct a visualizing board.

At a manufacturing company, due to the competition the price is reducedtowards the manufacturing cost. Therefore it is important to maintain control ofones costs and keep calculations up-to-date.This thesis deals with cost accounting at a aluminium-processing company. The report focuses on calculating machine cost per hour since the manufacturing costs are the major part of the total product cost.Managers on the company believe that the costs they use in calculations todayneither is up-to-date nor advantageous in a market aspect and due to that their calculations need to be revised. The machines cost per hour is a major part in the manufacturing calculation. The company wants to provide a competitive price that also covers their costs.

The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Skillingaryds stålrörsindustri AB handles different kinds of steel pipes and got theirmarket mainly in the furniture industry and in department stores. At the momentthe company find themselves in a strong up going course. In a few years thecompany?s turnover has increased with over 10 million SEK. This has led to ademand for structure changes and reorganizing through the company.

Rapporten beskriver ett examensarbete som utförts som en avslutning på Civilingenjörsprogrammet inom maskinteknik med inriktningen konstruktion på Luleå tekniska universitet, LTU. Examensarbetet utfördes i samarbete med Jama Mining Machines AB av Johan Forslund, delvis på plats i Skelleftehamn och delvis på LTU. Målet är att öka hållfastheten på två av Jama Mining Machines komponenter som återfinns i bommen på skrotaren SBU 8000 med rotator. Detta genom att ändra de specifika komponenternas konstruktion. En grundläggande nulägesanalys av de befintliga komponenterna genomförs för att identifiera vilka förbättringar som är nödvändiga till den nya designen.

This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

This study will chart the changeover work, with a standpoint in the SMED-theory, at the company Peter Ernst AB in Värnamo. They are suppliers in plastic moulding industry and delivers to amongst other Saab in Trollhättan and Scania. The company are in a very competitive market, and they have to make manufacturing more efficient and rationalise their costs to be able to compete. A big problem, which the company has identified, is their long changeovers. It brings higher costs, a more stressful work climate and holds back the company from becoming more efficient.Field studies will be conducted on the changeover, which will be observed and filmed.
