New encapsulation concept for robot controller cabinet / Nytt inkapslingskoncept för robotstyrskåp

Guo, Siyu January 2020 (has links)
Robot controller cabinets are specified with interfaces which make it possible to connect different modules for completing numerous tasks that are chosen for the robot manipulators. Different interfaces will be utilized depend on the kind of tasks and settings that are chosen. Thus not every interface will be put into use in a controller cabinet, some are left behind. In order to fulfill the encapsulation standards of electrical enclosures, the unoccupied interfaces are covered and sealed with on-screwed cover plates and gaskets during the assembly of the cabinet. However, a new method for encapsulation hope to be investigated and introduced to improve the current solution with respect to the encapsulation requirements from ABB.  The introduced new solution is a knockout concept. The detailed design is investigated with the help of finite element analysis with the explicit dynamics method used for simulating the punching processes of the knockout designs. Where three different design variables are put into consideration for finding the most optimum knockout design.  The results show that, for the particular steel plate provided by ABB, a V-grooved knockout design with a grooving angle of 90 degrees and an unaffected thickness of 0.1 mm has the best performance in terms of smoothness at edges and the amount of plastic strain occurred in the material.  Traditional manufacturing methods to manufacture the obtained knockout design appear to be extremely time consuming and thus not profitable for mass production. However, a type of fairly recent developed grooving machines, the so called V-grooving machine, is believed to be able to solve the manufacturing problem. / Robot styrskåp är specificerad med mängder gränssnitt vilket gör det möjligt för anslutning av olika moduler till att kunna fullborda de uppgifterna valda för robot manipulatorerna. Olika gränssnitt utnyttjas beroende på den typ av arbetsuppgift och inställningar valda just för den. Därför kommer inte alla gränssnitt att kunna tas i bruk i ett styrskåp, vissa lämnas kvar. För att kunna uppfylla inkapslingsstandarden för elektriska kapslingar är dessa obesatta gränssnitt täckt och förseglat med påskruvad täckplåtar och packningar under montering av styrskåp. En ny inkapslingsmetod hoppas att kunna utredas och introduceras till att förbättra den nuvarande lösningen med avseende på de inkapslingskraven från ABB.  Den introducerade lösningen är ett knockout koncept. En detaljerad konstruktion undersöks med hjälp av finita element analys med explicit dynamik som grunden till att simulera knockout processer. Där tre olika design parametrar tas i beaktande för att hitta den mest optimala knockout konstruktionen.  Resultaten visar sig att, för den här särskilda stålplåten som tillhandahålls av ABB, en V-spårad knockout konstruktion med en spårvinkel på 90 grader och en tjocklek på 0.1 mm har den mest tillfredställande prestandan med avseende på jämnhet, d.v.s. reduceringen av vassa kanter, och mängder av plastiska töjningar som inträffas i materialet efter knockout processen.  Traditionella tillverkningsmetoder till att tillverka en sådan knockout konstruktion visar sig vara väldigt tidsödande och anses därför inte vara lönsamt för massproduktion. Emellertid upptäcks det en typ av relativt nyutvecklad spårmaskin, så kallad V-grooving machine, som tros att kunna lösa tillverkningsproblemet.

Applicability Study of Software Architectures in the Discrete Manufacturing Domain

Bizhuta, Ermal, Carhoshi, Dhespina January 2019 (has links)
Manufacturing, under the umbrella of the latest industrial revolution, has gone through enormous changes in the last decades to then later evolve in what we know now as smart manufacturing. Different companies and entities have developed their own versions of architectures for intelligentand digitalized manufacturing systems. Ideating a exible and safe architecture is one of the first steps towards a system that intends to be applicable in different environments, regardless of the vast variety of possibilities available. For this purpose, the following thesis presents an investigation on the state-of-the-art solutions of the most recent digitalized cloud-based system architectures in the domain of discreet manufacturing. Based on an initial system architecture conceived from the company ABB, an evaluation of this architecture was conducted, by taking in consideration the existing systematical approaches to the digitalization of this industry. In the following thesis work, we investigate, describe and evaluate the limitations and strengths of the most recent and known architectural approaches to cloud robotics. Finally, a few key remarks are made towards ABB's initial solution but also to the industry in general. / PADME

ABB Gate Model : En processledningsmetod för ABB:s produktutveckling / ABB Gate Model : A Process Management Model for Product Development in ABB.

Hallqvist, Stina, Moström, Johanna January 2003 (has links)
<p>Organisations tend to focus more and more on product and process development to increase their competitiveness. Several major organisations, among them ABB, have developed models aimed to more effectively control and manage product development processes. ABB is using its standardised model ABB Gate Model for this. The purpose of this thesis is to analyze how the introduction of ABB Gate Model has affected the outcome of decisions and also the decision-making in the product development process. The study is limited to elucidate the version of ABB Gate Model handling product development projects. No deeper study is conducted regarding the information used or the criteria for the gate decisions; instead, the focus is to findelements in basis for the decision- making that have a greater significance for the outcome at some gate or at specific types of gate decisions. The empirical data of the thesis has to a great extent been collected through interviews with respondents from both of the studied units and also the unit in charge of the implementation and development of ABB Gate Model. The study shows that ABB Gate Model does not to any significant extent affect the outcome of the decisions in the product development projects. In general, the same decisions are made as before and projects are seldom cancelled. The foremost effects of ABB Gate Model at the units are: increased clarity and support to the operational work, improved co- ordination between the units functional departments, and contributed to make essential aspects of the product development projects visible and taken into consideration.</p>

ABC och ekonomisystem : En studie av Volvo Construction Equipment Components AB / ABC and Accounting Information Systems : The Case of Volvo Construction Equipment Components AB

Gustavsson, Tomas, Muänoz Elvelin, Pedro January 2001 (has links)
<p>The accounting information system comprises budgeting, accounting, and costing. The accounting information system has, traditionally, constituted an integrated system where the different elements collaborate. If ABC is introduced this order is disturbed, since ABC is based on another logic which cannot easily be integrated with budget and accounting. ABC, therefore, is usually used parallely to the conventional costing method. There are, however, companies that have taken its ABC one step further by letting it replace the old costing model and integrate it with the accounting information system. Our purpose is to describe how a well-integrated ABC has been designed and analyse its general possibilities to create an integrated ABC and accounting information system. In order to fulfil this purpose we have based our empirics on interviews and internal documents from our case company; a subsidiary to Volvo. In the case we have studied, a high degree of integration has been achieved through a partial adaptation of ABC as well as the remaining components of the accounting information system. The account of overhead revenues has changed from focusing on hours to register based on articles produced. The budget, at a whole, continues unchanged, but some rationalisations in the budget process have been a positive consequence of the adoption of ABC. ABC has been adapted by letting the accounts plan and the cost pool structure remain unchanged and no division based on activities has been realised. The procedure of the studied case can be applicable to other constructing enterprises facing the decision to adopt or integrate ABC to its accounting information system.</p>

Sarbanes-Oxley Act - Uppfyller den sitt syfte? : En studie av svenska bolags åsikter om SOX och vad den inneburit för dem

Sahlén, Karl-Magnus, Hagman, Johan January 2010 (has links)
<p>Sarbanes-Oxley Act, SOX, har inneburit stora förändringar för de företag som</p><p>är noterade på en amerikansk börs. Med höga krav på en struktur för interna</p><p>kontroller av processer inom företaget har detta inneburit mycket arbete för</p><p>företagen och revisorer. Framförallt under införandet men även efteråt i det</p><p>dagliga arbetet.</p><p>I denna uppsats redogör vi för hur svenska företag ser på Sarbanes-Oxley Act</p><p>och vad de anser om hur väl regelverket uppfyller sina mål att förhindra fel</p><p>och fusk i redovisningen samt den finansiella rapporteringen. För att komma</p><p>fram till våra slutsatser har vi intervjuat sex olika personer som på något sätt</p><p>kommer eller har kommit i kontakt med SOX. Det är svar från personer på</p><p>ABB, AstraZeneca, Autoliv, Ericsson samt Ernst & Young som varit grunden</p><p>i vårt arbete.</p><p>Det visade sig att de alla ansåg att SOX höjt kvaliteten i deras redovisning och</p><p>hjälpt dem att hitta felaktigheter i ett tidigare skede. Dock är det tveksamt om</p><p>regelverket motverkar de riktigt omfattande bedrägerier vi sett och kanske</p><p>även i fortsättningen kommer se.</p>

Konsten att belöna goda prestationer : en studie i projektorienterad miljö / The art of rewarding performance : a study in a project based environment

Ahlström, Jenni, Larsson, Lina January 2002 (has links)
Bakgrund: I de kunskapsintensiva företagen av idag krävs en ny utformning av belöningssystem. Eftersom de mänskliga resurserna utgör en viktig del i konkurrenskraften är det också alla medarbetare i företaget som ska beröras av ett belöningssystem. Utmaningen ligger i att företagets övergripande målsättning med belöningssystemet måste fogas samman med medarbetarnas uppfattning om vad som motiverar för att det ska få avsedd effekt. Syfte: Syftet med uppsatsen är att analysera utformningen av belöningssystem i en komplex projektorienterad miljö, med hänsyn tagen till såväl företagsledningens önskemål om beteenden och prestationer att premiera som till vilka belöningar sommotiverar medarbetarna. Genomförande: Intervjuer har genomförts med 7 chefer och 8 medarbetare på ABB Power Systems. Dessutom har en enkätundersökning bland medarbetare inom enheten genomförts. Resultat: Studien visar att önskvärda prestationer och beteenden kan specificeras i måluppfyllelse respektive goda insatser. I en projektorienterad miljö bör det finnas utrymme för att belöna såväl enskilda individer som grupper. Belöningar som utdelas ska variera både i förhållande till vad de består av och med avseende på deras värde.
