This report looks at the possibility of designing a universal adapter for Flat Blade windshield wipers in cooperation with European Automotive Supplier AB. To understand and see if this is possible, a research and an extensive patent search where done. Then to add structure to the project a Ganttschematic were developed. To generate good and solid ideas, different methods for product development were looked upon. When a method was chosen and applied, a series of concepts emerged. Now the focus was to design and construct all the pieces. The desired manufacture procedures were looked upon as well as materials. Lot of time where spent on designing a lock mechanism to meet the demands European Automotive Supplier AB hade given. To choose the right concept the team used a set of selection matrix for the different ideas. After the choices were made, different prototypes were made of the concepts.

<p>Lars Höglund AB is one of Scandinavia’s most qualified manufacturers of sheet metal products and provides custom designed products of very detailed precision. One of the main methods of manufacturing is laser cutting. When Lars Höglund AB signed up a new customer, with high demands in tolerances for the products, Lars Höglund AB thought it would be necessary to know the capability of the laser cutting machine. Also the process of how to retrieve this capability was interesting.</p><p> </p><p>The capability will be researched for the following elements:</p><p> </p><ul type="disc"><li>Cutting right angles in squares with a corner radius of 1 mm</li><li>Cutting corners which are not right angle</li><li>Cutting of circles with constant radius</li></ul><p> </p><p>Measurements were made on 150 pieces of sheet metal details, which had been cut out by the machine.  The data from the measurements where later used to study the capability. The capability study includes such things as calculations of capability indexes C_p and C_pk, the calculations are based on histograms and lean-mean-curves, constructed from the measurement data. The capability of the laser cutting machine was high except for some elements. Those elements with minor capability were the cutting of corner two and three for the rectangles which had a smaller radius than expected, side X for the triangles which were too long and also the diameter of the circles were too big. Advices on how to correct the faults have been given if Lars Höglund AB wants to further more improve the capability of the machine.</p>

I denna rapport presenteras olika koncept på hur utformningen av hållare till baklyktor kan se ut. Arbetet är ett samarbete mellan författaren och Specialkarosser AB. En mängd olika lösningar har utarbetats där det till slut uppenbarats fyra olika koncept på lösningar. Dessa olika lösningar har vägts mot varandra utifrån den metod som använts. Resultatet av dessa bedömningar blev ett koncept där tanken bakom lösningen är att utforma en kapsel som efterliknar det formspråk som finns på framlyktorna på lastbilar, samt att den ska kunna kombineras med flera likadana kapslar för att få fler lyktor.

<p>Wear of hardmetals is a complicated topic because the wear resistance and the wear mechanisms are influenced by microstructural factors. Although edge wear resistance has a vital importance, most of the researches made in laboratories are related to flat wear resistance using coarse abrasive paper. This situation produces problems with the prediction of abrasive wear behaviour and with the estimation of the lifetime of cutting edges of different kinds of tooling.</p><p>Several studies have been done in order to clarify edge wear behaviour. It has been published correlations of the edge toughness to the load and to the bulk fracture toughness. In those publications coarse abrasive or Vickers indenter were used.</p><p>In the present research, edge shaped specimens of WC-6wt%Co grades were investigated. In order to compare the obtained results for flat sliding and edge wear behaviour two test arrangements, pin on flat disc and edge on flat disc were employed. The specimens were tested using 120, 320, 800 and 2400 mesh SiC abrasive paper and the worn surfaces were investigated using SEM instrument to evaluate wear mechanisms.

However, both edge and flat wear results were similar in; 1) large WC grain sized hard metals wore more than fine grain sized against coarse abrasive paper whereas the reverse occurred against fine abrasives, and 2) wear mechanisms were mainly ploughing (or grooving) for fine grain sized hardmetals in all cases, whereas wear mechanisms changed from ploughing to binder removal and carbide pull-out going from coarse to fine abrasive paper.</p>

The main point in this diploma work lies to a beginning on analysis of the existing model of WoodEye scanner. The analysis aims to forming a view and understanding of how the scanner is designed and how it functions, and certain conditions around the scanner. On the basis of the result from the analysis and obvious criteria, has a number concept proposals been put forward. The concept proposals has then been evaluated and been compared with current concept, obvious criteria and compared to each other. The best proposal has then been developed far to a completed concept.
