Um dos métodos de fabricação de engrenagem em grande escala é baseado na usinagem por ferramentas de corte denominadas Cortador Hob ou Fresa Caracol. Esse método permite agilidade e precisão. A máquina e a ferramenta destinadas a esse processo são para aplicação específica na fabricação de dentados em engrenagens e eixos, fazendo-se necessário portanto um aprofundamento na otimização, melhor utilização dessas ferramentas. A não substituição da ferramenta no momento correto implica em dois problemas: ou ela poder ser trocada antes do término da vida ou ela pode ser usada em excesso e formar o chamado desgaste excessivo, o que reduz o número de afiações do cortador. O ponto a ser estudado o qual se trata essa dissertação é poder estimar a quantidade de peças a ser produzida com cada uma dessas ferramentas. Entretanto, sabe-se que uma mesma ferramenta pode ser aplicada a diversos tipos de peças, com variação de diâmetro e espessura, o que caracteriza a complexibilidade desse processo. Para isso foram coletados dados de usinagem e de desgaste da ferramenta em função das dimensões do par peça/ferramenta. Depois foram determinada curva padrão de desgaste em relação ao par peça/ferramenta e a partir dessa curva padrão, determinar a vida dos cortadores em quantidade de peças a serem fabricadas. Em seguida, os testes realizados puderam comprovar a efetividade dessa correlação. / The method of manufacture of gear on a large scale is based on process that use cutting tools, called Hob or “Caracol”. This method allows the speed and accuracy. The machine and tool designed for this process are specific for application in the manufacture of toothed gears and shafts.

Failure to replace the tool at the right time involves two problems: or it can be exchanged before the end of life, or it can be overused and form the so-called excessive wear, which reduces the number of cutter sharpenings. The point of study from which it comes this work is to determine the quantity of parts to be produced with each of these tools, it know that the same tool can be applied to various types of pieces, ranging in diameter and thickness, which characterizes the complexity of this process. Therefore data about machining tool wear depending on the size of the pair part / tool were plotted collected. After that, standard curves of wear in relation to the pair part / tool and by this standard curve, to determine the life of the cutters in quantities of parts to be manufactured. Soon after, the tests performed could proved the effectiveness of this correlation.

This project was performed in collaboration with Electrolux and takes off in the transition towards a circular economy where products are considered to have multiple life cycles and need to be designed to be able to cycle longer through maintenance and repair. Electronics are rarely designed to fit into circularity thus an induction hob was chosen to show this principle. The research question for this project was therefore how an induction hob should be designed and what other tools are needed to enable a non-experienced user to repair it to provide the perfect repair experience. The project began with a literature study which investigated the concept of circular economy, also how to design for circularity and sustainability. It moved on to investigating why people get rid of products and why people don’t get rid of products. It was found that there are many barriers at the individual’s level and at a structural level, as that people feel that they should replace their products after some time, as well as economical aspects. The main reasons why people keep their products are the emotional attachment to product or that it cost less than to repair than replace the product. A user study was performed to investigate the repair experience for an induction hob today. It was done through letting people disassemble an induction hob while they answered questions about the experience. The insights from the literature and the user studies were narrowed down to the following problems to be solved: Easy diagnosis, easy opening, identification, and replacement of the broken module. Concepts were prototyped and more rounds of user studies were performed with these. The final concept lets the hob stay in the counter while the repair is performed. It contains a tray which resembles a “bento box” in which the internal modules are placed that also functions as a hiding area for the cables in the hob. A new opening mechanism has been designed and the internal modules are now more approachable. The final result only considers barriers for repair at the individual’s level, lowering them to make the repair process easier. The diagnosis has become simpler through the NFC tag and the provided instructions and identification of modules was easier because of the icons. The design follows the Electrolux brand guidelines and gives the user the feeling that they can touch and replace the modules. Also, an electrical safety system has been added. The final concept gives a non-experienced user the tools and confidence to perform the repair themselves. When the user has performed the repair themselves, they are more prone to keep the hob for longer. / Det här projektet gjordes tillsammans med Electrolux och tar avstamp i förändring mot cirkulär ekonomi där produkter kan ha flera livscykler och därför behöver vara designade för att kunna underhållas och repareras. Elektronikprodukter är sällan designade för att passa in i cirkulär ekonomi och därför valdes en induktionshäll för att påvisa principen. Frågeställningen för projektet var hur ska en induktionshäll designas, samt vilka andra verktyg behövs, för att en icke erfaren användare ska kunna få den perfekta reparationsupplevelsen. Projektet inleddes med litteraturstudier som undersökte cirkulär ekonomi och hur produkter kan designas för att sträva mot hållbarhet och cirkularitet. Vidare undersöktes varför människor gör sig av med produkter samt varför människor behåller sina produkter. Det visade sig att det finns många barriärer både på individnivå och på strukturell nivå, såsom att människor efter en tid känner att de bör byta ut sina produkter, såväl som ekonomiska aspekter. Människor behåller sina produkter för att de har känslomässiga band till dem eller för att det kostar mindre att reparera än att köpa nytt. Flera omgångar av användarstudier utfördes, bland annat fick personer ta isär en induktionshäll för att kunna analysera upplevelsen av reparationen idag. Från användarstudierna och litteraturstudien upptäcktes följande problem som behövde lösas: diagnosticering, öppna upp hällen, identifiera och byta ut den trasiga modulen. Koncepten utvärderades kontinuerligt genom användartester med modeller. Det slutgiltiga konceptet låter induktionshällen vara kvar i köksbänken när reparationen utförs. En ny öppningsmekanism konstruerades och de interna modulerna designades om för att kännas mer tillgängliga och vänliga för användaren. I induktionshällen finns en inre ram som efterliknar en så kallad “bento box” där de interna modulerna placeras och alla kablar göms. Slutresultatet tar endast hänsyn till barriärer för reparation på individnivå och har sänkt dessa i de olika faserna i reparationsresan för att förenkla denna. Diagnostiseringen har blivit enklare genom NFC-taggen och de medföljande instruktionerna. Identifieringen av moduler har blivit enklare med hjälp av ikonerna. Designen följer Electrolux varumärkesriktlinjer och ger användaren känslan av att de kan röra och byta ut modulerna. Dessutom har ett elsäkerhetssystem lagts till. Det slutliga konceptet ger en icke-erfaren användare verktygen och självförtroendet att utföra reparationen själv. Efter den upplevelsen är de mer benägna att behålla hällen längre.

The diploma thesis present technology production of draining outlet. This is a rectangular deep drawn part, where basic shape is formed in two towing operations now. The used material is an austenitic stainless steel 17 240 with thickness 1 mm. According to the entry documentation the production technology was not change – current technology (it means drawing without thinning the wall) is most suitable. Based on technological and control calculations two-operations production was determined, which will take place in the united conventional instrument. The hydraulic press with marking Dieffenbacher PO250, which has a magnetic tool clamping, per stroke will perform here both operations. The payback was calculated for yearlong production 50 000 pieces after 0,8 years. The proposed production will make the current production more efficient including economic benefits.

Bien qu’une vaste littérature musicologique porte sur Joseph Haydn (1732-1809), aucune ne comprend une étude exhaustive de l’ensemble de ses sonates pour clavier, incluant les premières oeuvres composées dans la décennie 1750. La présente recherche se propose de combler en partie cette lacune par le biais d’une analyse des 52 premiers mouvements Hoboken (Hob.) XVI. Basée sur des outils empruntés principalement à William E. Caplin, Brian Alegant et Don McLean, cette étude constitue un premier pas vers une typologie du premier mouvement de sonate chez Haydn, permettant par le fait même de refléter l’évolution de la forme sonate, en mutation tout au long de la vie créative du compositeur. Dans un premier temps, une série d’analyse capliniennes permet d’effectuer un survol des différentes formes qui composent le corpus à l’étude afin d’en dégager certains procédés spécifiques, nommément l’exploitation de techniques formelles à des fins de développement thématique, ainsi que l’emploi marqué d’ambiguïtés formelles et fonctionnelles. Dans un second temps, une analyse de la disposition du matériau suggère une conception du premier mouvement en forme sonate basée sur le développement thématique d’un nombre réduit d’idées musicales, dont la répétition est compensée par plusieurs procédés dont les principaux sont la variation structurelle dans la section de réexposition et l’emploi de différentes fonctions formelles à chaque itération. Prises dans leur ensemble, ces analyses démontrent que l’ensemble des premiers mouvements de sonate pour clavier Hob. XVI sont liées par une certaine imprévisibilité créée spécifiquement au moyen de la réutilisation thématique et des fonctions formelles. / Although there is a vast musicological literature on Joseph Haydn (1732-1809), none includes an exhaustive study of all his keyboard sonatas, including the first works composed in the 1750s. The present research aims to fill this gap through an analysis of the 52 first movements of the keyboard sonatas Hoboken (Hob.) XVI. This study constitutes a first step towards a typology of Haydn’s sonata first movement, thereby making it possible to look at the evolution of the sonata form, under development throughout the composer's creative life. Initially, a first series of Caplinian analysis allows an overview of the different forms that make up the corpus under study in order to identify certain specific procedures, namely the use of formal techniques for thematic development purposes as well as the marked use of formal and functional ambiguities. Secondly, an analysis of the arrangement of the material suggests the conception of the sonata form’s first movement to be based on the thematic development of a reduced number of ideas, the repetition of which is compensated for by several processes, the main ones of which are structural variation in the recapitulation section as well as the use of various formal functions for each iteration. Taken as a whole, these analysis show that the 52 first movements Hob. XVI are linked by the expression of a certain unpredictability caused specifically by thematic restatement and the use of various formal functions.
