This report describes a Bachelor thesis work in which a robotised laser welding cell has been modelled and simulated for the purpose of making a presentation movie. The report shows that the work has been concentrated on making the movie from the modelling phase through the recording of the movie and ending up with the editing of the final presentation movie. A pre-study was made prior the Bachelor thesis work. In the pre-study a literature study was conducted about measurement and calibration of a welding cell. Measurement of almost all equipment in the entire cell was also conducted in the pre-study.

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.

Biogas är en förnyelsebar energikälla som tillverkas genom att organiskt material som matavfall bryts ner av mikroorganismer under anaeroba (syrefria) förhållanden. Regeringen har satt upp mål för en högre matavfallsutsortering vilket leder till ökad mängd tillgängligt substrat till biogasproduktion.Matavfallet som samlas in börjar brytas ner under tiden det transporteras och lagras. Syftet med studien var att undersöka hur länge matavfall lagras, ta fram ett representativt recept på ett genomsnittligt matavfall i Sverige och utvärdera hur mycket metanpotential som försvinner från matavfall med avseende på lagringstid, insamlingssystem (papper- och plastpåse) och lagringstemperatur (22°C och 6°C) genom laboratorieförsök.Den genomsnittliga lagringstiden för matavfall från villor och flerbostadshus i undersökningen var sex dagar. Ett recept för matavfall har tagits fram med hjälp av litteratursökning och modifiering av recept i Avfall Sveriges rapport U2010:10. Laboratorieförsöken visade att skillnaden i metanpotential mellan plast och papper var tydlig vid 22°C, då metanpotentialen sjunker, men obefintlig vid 6°C.För att uppnå maximal metangasproduktion från matavfall under den varma delen av året så är plastpåsar bättre då de har en mer konserverande effekt på matavfallet än papperspåsar.

To meet the needs and demands of the costumer, accurate information about how much is available in stock is necessary. When the information in the system does not match the physical inventory, inventory inaccuracy occurs. Inventory inaccuracy is common among companies and may contribute to increased labor cost, excess inventory, production disruptions, waste of time, late deliveries, poor service and lost customers.The purpose of this study is to identify contributing factors to inventory inaccuracy for business with outdoor storage. The study also aims to investigate how efficiency factors can reduce the inventory inaccuracy for business with outdoor storage.A case study was conducted to answer the purpose. A company in the steel industry was chosen to examine inventory inaccuracy on business with outdoor storage.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.

In an ever more competitive environment Sandvik Materials Technology,SMT, runs a large-scale program to improve their processes for product development.The purpose with the program is to increase the company?s profitability by increasingthe number of new products in their product portfolio. The strategies SMT is usingfor reaching their goals are to change the way they work with product development byreducing lead time and learning how to prioritize products with the highestprofitability. In the R & D Department the work of improvement pursue by adaptingLean R & D to their way of working. Lean R & D encourages working withcontinuous improvements and eliminating waste.The main purpose for this Master?s Thesis is to develop didactic support to make iteasier to implement Lean in SMT R & D department.

I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Trådgnistning (på engelska Wire Electrical Discharge Machining eller WEDM) är en termiskbearbetningsprocess för att med en trådelektrod skära i elektriskt ledande material. Metoden har teoretiskt sett många fördelar och relativt få nackdelar. Intervjuer i studien visar att trots detta så undviker flera industriföretag om möjligt denna process. Syftet med studien är att utifrån de teoretiska fördelarna som anges i litteraturen undersöka vad företag i Sverige anser vara de mest relevanta praktiska fördelarna med trådgnistning som bearbetningsprocess. En internetbaserad enkät har skickats ut och besvarats av 20 industriföretag runtom i Sverige.

Denna rapport i form av examensarbete för utbildningsprogrammet Managing Technology and Business Projects, är en del i Volvos framtida produktions-/ produktstrategier.Uppsatsens syfte är att ur ett produktionsperspektiv understödja Volvo Construction Equipment i Braås i strävan mot en ökad modulindelning av ramstyrda dumprar, som en del i utvecklingsarbetet för en effektivare produktion. Resultat har uppnåtts genom analys av intern och extern benchmarking jämfört med den teori som finns inom ämnesområdet modulindelning. Huvudresultatet visar att teorin och verkligheten skiljer sig genom att modulindelning ska anpassas individuellt utifrån varje företag och inte fungerar som en generellt applicerbar process. Slutsatsen visar att Volvo CE i Braås måste utveckla en egen handlingsplan och kravspecifikation utifrån egna definitioner som är skräddarsydda specifikt för företaget.I rapporten presenteras förslag till ovanstående handlingsplan för modulindelning på Volvo CE i Braås..

Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise.This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE.

Detta examensarbete är resultatet av en utredning av tvättning och rengöring av produkter som tillverkas på Volvo Construction Equipment Components AB i Eskilstuna. Arbetet är uppdelat på två huvudområden, tvättning i processen samt slutgiltig renhet. Skillnaderna mellan dessa är framförallt att det finns fastställda krav på den slutgiltiga renheten för artiklarna men en motsvarande märkning saknas för de olika tillverkningsstegen. Idag tvättas ungefär 70% av TMAs artiklar i en central tvättstation. I och med detta uppstår en hel del problem med ledtider och kvalitet.
