The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New Manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those Manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the Manufacturing process.

On today?s competitive market, it is difficult to achieve profitability trough high prices on manufactured products. Profitability must be obtained through low Manufacturing costs, high quality and short lead times. One of the companies on the market is Sandvik Coromant, manufacturer of tools and chips for metal cutting. This master thesis investigates the methods of Manufacturing for boring bars at the Manufacturing unit GVH4 at Sandvik Coromant in Gimo, Sweden.

In recent years, Lean has been implemented in a variety of companies with focus areas that differ from the conditions that characterizes Manufacturing. This transfer has contributed to fairly superficial results because companies almost exclusively focus on Toyotas methodology and not on the goal of Lean. The effort of transforming Lean from Manufacturing to any organization requires a definition on a general level and a view of Lean as a system. One of the core principles of Lean and the foundation of continuous improvements is standardized work. In product development there is a negative view on standardized work, where the engineers state that the principle is not applicable for knowledge processes that include non-repetitive and creative work.In the framework of this master thesis literature has been studied to find support that standardized work is applicable for product development and areas that include knowledge processes.

This essay answers the question: How can a Manufacturing business fulfill the information demand in the processes; purchasing, production, warehousing, order and delivery?The question has been answered through different kind of studies, such as literature, documents, Internet search, interviews and observations. The essay is written from a hermeneutic point of view and by using qualitative research. The result has been validated by two different Manufacturing businesses.A simple information logistic model is the result of a comparison made between theory and empery. The aim of the model is to describe how a Manufacturing business can fulfill the information demand by using different methods.

The aim with this study was to investigate the effects a change of Manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the Manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.

The purpose of this project was to design an adjustable gutter bracket for Lindab Profil AB. Lindab currently manufacture a gutter bracket that is adjustable in angle, however, this model has some drawbacks.  One of it´s shortcomings is that it is somewhat difficult for the customer to mount.  Another problem with Lindab?s current model is that the design makes Manufacturing unnecessarily complex. The new gutter bracket, that we have constructed, does not have these problems. It is adjustable for different roof pitches.

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s Manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific Manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the Manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the Manufacturing process, Manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..

Background - Swedish trade and industry primarily involves small corporations, including small Manufacturing corporations. Currently, most costing models that are used are based on studies accomplished at large corporations. This conveys to the fact that product costing that occurs at small Manufacturing corporations is based on all complexities that large corporations bring, which rarely match with small corporations. It occurs that small Manufacturing corporations unconsciously rely on incorrect information that has been calculated based on great corporations? product costing.

AB Sandvik Cormorant?s production unit in Gimo has identified a need to examinethe handling of products between operations with the purpose of generatingproposals of improvement for the product handling.The aim of this project is to study the existing Manufacturing process and givesuggestions for improvement. The proposals should reduce the manual handling ofproducts, decrease the risk of damaging the products during the Manufacturing andform a basis for increased traceability. Based on a mapping of the Manufacturingprocess and the problem description, a specification of requirements has beencomposed.The mapping of the Manufacturing process suggests that a change of the currentsystem is required. The company is recommended to decide how the producthandling between operations should be performed as guidelines for the productionteam.
