The VMS is a robot milking system of DeLaval International AB. It has been observed that a layer of residue remains on the camera lens after cleaning. The camera is used to locate the teat and apply the milking cups. Even though after automatically cleaning with a sponge, it is very difficult to remove this layer. This study has been conducted to find out if a new cleaning station utilizing steam can have better cleaning results concerning the mentioned problem. A test setup was built to perform several tests. The boiler is capable to supply steady steam with the same pressure and temperature every milking cycle, which is approximately 8 minutes. Tests further on showed that the inside camera housing temperature not exceed 35°C, which remains under the required limit of 50°C. After the steam has cleaned the lens compressed blows and cools the remaining droplets left behind. The comparison between the sponge and the steam cleaning method confirms that the steam cleaning method is able to remove the contaminations more sufficient than the sponge. One of the contaminations is milk which is the worst kind. Studies showed that milk tends to denaturize when heated above 60°C. This could form a layer of burned proteins on the lens.

This thesis is focused on possibilities of high-speed digital cameras and their use in different fields of industry. It describes the mechanism of chip forming in orthogonal turning. Subsequently experiments focused on comparison and select the right lens and method of illumination are implemented. These findings are then used in obtaining the record of chip forming by using high-speed digital camera. Key words

Inom materialforskning och en stor del av den mekaniska och mekatroniska industrin finns ett intresse av att utnyttja blixtröntgen för att studera dynamiska händelseförlopp i inneslutna system, ej synbara med konventionella kameror. I och med att många rörelser inom de benämna områdena även sker i hyperhastighet så tillåter blixtröntgen statisk bildtagning  av rörelser i flera km/s, med minimal rörelseoskärpa. Detta examensarbete har grundats i att utveckla och utvärdera koncept för en komplett systemuppställning inklusive höghastighetskamera för denna tillämpning.  Syftet med arbetet har således varit att både identifiera och definiera produktens ingående produktkrav, för att spegla den funktion och syftet som önskas uppfyllas, och utifrån detta generera koncept för uppställningen på systemnivå, samt för separata  komponenter. Slutligen har de utvalda koncepten utvärderats genom praktiska prestandatester för att kontrollera dess uppfyllelse av produktkraven. Datainsamlingen för arbetet skedde i form av flertalet praktiska experiment för insamling av kvantitativ data, samt återkommande uppföljningsmöten med involverade medarbetare för insamling av kvalitativ data.  Undersökningen resulterade i ett koncept för en slutprodukt, benämnt funktionsprototyp som motsvarade och uppfyllde de definierade produktkraven vad gäller funktionalitet och prestanda. En diskussion fördes även för den kommande vidareutvecklingen av slutprodukten, inklusive färdigställandet av samtliga koncept och den följande designfasen. / In materials research and a large part of the mechanical and mechatronic industry, there is an interest in using flash X-rays to study dynamic events in enclosed systems, not visible with conventional cameras. Since many movements within the named areas also take place at hyper-speed, flash X-rays allow to capture static images of movements in several km / s, with minimal distortion. This thesis has been based on developing and evaluating concepts for a complete system setup including a high speed camera for this application. The purpose of the work has thus been to both identify and define the product's included product requirements, to reflect the function and purpose that is desired to be fulfilled, and based on this generate concepts for the set-up at system level, as well as for separate components. Finally, the selected concepts have been evaluated through practical performance tests to check its compliance with the product requirements. The data collection for the work took place in the form of two practical experiments for the collection of quantitative data, as well as recurring follow-up meetings with involved employees for the collection of qualitative data. The study resulted in a concept for an end product, called an end concept that corresponded to, and met the defined product requirements in terms of functionality and performance. A discussion was also held for the further development of the end product, including the completion of all concepts and the subsequent design phase.
