Utrustning för automatmontering av ackumulator
This report deals with an exam report written by Olle Hjalmarsson and Thomas Likar, students at Högskolan i Halmstad. The project was carried out for Haldex Traction AB in Landskrona whose business consist of manufacturing automatic all wheel drive systems (AWD-system). These systems consist of a plate clutch which activates all four wheels of a 4-wheel driven vehicle. An important component in these clutches is the accumulator which basically consists of a piston under the load of a spring which creates an oil pressure with the help of an electric motor used for actuating the clutch.At Haldex difficulties has been experienced regarding the Assembly of the accumulator parts due to the small tolerances between the piston and the hole of the accumulator in the cast aluminium housing. Attempts have been made to assemble the parts in existing robot cells.
Svenska kyrkans funktion i den palliativa vården : - ett religionssociologiskt perspektiv
Through the lenses of religion?s role in society, the purpose of this thesis is to examine, the role of the Church of Sweden in providing support to people at the end of life. Questions asked are: "What types of spiritual support is offered by the Church of Sweden during terminal care provided in patients' homes and how is this support expressed in church orders, Assembly instructions, plans of operations and congregation letters?" and " How can the work of the Church of Sweden be understood, based on theories of religion's role in society? The method used is a content analysis of the Church Order, Assembly instructions, plans of operations and congregation letters in 17 different congregations within the diocese of Lund. I then engage in a discussion with theories on differentiation and the privatization of religion as a means to interpret my results.

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.
Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation
Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.
Vridspjäll
Our education at Halmstad University was completed with a degree project. Our task was to improve an already existing pneumatic damper to Nederman in Helsingborg.
Overall we have made necessary calculations to make the design of the existing damper smaller. When these calculations were done, we moved on with an analysis of the existing damper in order to figure out what improvements could be made on each part of the damper.
The result of this project is a smaller and a more supple design of a pneumatic damper. To this we have also created complete drawings, calculated material expenses; we have also created an Assembly of a pneumatic damper in Catia v5..

Robotiserad montering av styrskåp
Syftet med detta arbete var att undersöka möjligheterna för montering av ett styrskåp av modell Motoman NX100 NOC1. För detta användes simuleringsprogrammet DELMIA. Roboten som användes nådde inte alla montage om skåpet var stationärt. Därför prövades först ett antal olika förslag för att lösa detta problem genom att transportera skåpet. Det koncept som bedömdes som mest pålitligt användes sedan för att skapa en mer ingående simulering.

It is easier to swallow an elephant in pieces. A way of measuring flexibility and quality. A study of DAS.
Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.
