- Adhesive joining is frequently used in the automotive industry. In the pursuit of reducing weight, adhesive joining is important due to the possibility of joining different types of materials. The process is often automatised in order to reduce cycle time. In this paper we aim to present a novel framework that includes detailed process simulation and automatic generation of collision free robot paths and in this way improve the quality of the joint and reduce both cycle time and processing time. To verify the simulations, the properties of the adhesive bead have been compared to experiments with good agreement. © 2016 The Authors.

- There is no type of manufacturing process that is not afflicted by variation. Activities intended to ensure the quality of a company's geometry processes are usually referred to as geometry assurance activities. One clear industrial problem is to understand the relations between the products concept and the manufacturing process. Dimensional data is a very important source of experience of how a product's geometry has worked in the interaction with the actual manufacturing system. Users therefore need good analysis and presentation tools of geometry outcomes to support both the product developers and production engineers in the analysis of the production output and its consequences. Today the dimensional data can be difficult to obtain or access, and is not necessarily presented in such a way as to provide the user with all necessary information. This paper presents how presentation and analysis tools of geometrical inspection data can be taken a step further. New functionality for feature based 3D visualization of inspection data has been developed which integrates the variation simulation platform and the inspection data database. The goal has been to create better tools for analysis of geometrical variation and increase the understanding of the sources of variation.

Acquisition of new knowledge in Swedish manufacturing companies - How could it be improved?
- 2017

Konferensbidrag (refereegranskat)abstract
- Experience has shown that new research does not reach out to companies and organizations in Sweden as desired. The spread and application of useful research results was found to be limited to relatively few companies. The situation is similar across the EU according to investigations. This means that many improvement possibilities are missed and probably also increased profitability and competitiveness. In order to explore the underlying reasons for this nineteen Swedish companies were asked about participation in an interview study. Nine agreed to participate and interviews among upper level management were accomplished in order to investigate how new knowledge was acquired and implemented. The interview study included 18 semi-open questions about: organizational relationships; decision levels; distribution of responsibility; cooperation between different departments; successful implementation factors; responsibility for ergonomics issues; management of assembly-related errors and conditions for effective knowledge dissemination. The results showed that the small businesses lacked sufficient resources to manage major changes and that binding subcontractor agreements counteracted possible improvements of product design and assembly solutions. In some cases additional implementation support is probably needed to succeed because time-consuming change initiatives that were not highly prioritized could often not be sufficiently considered. A critical mass of knowledgeable people was considered crucial to manage implementation of new methods and working procedures. It was perceived difficult to find research reports of interest for the own business. Only one company had an ergonomics specialist involved in early development phases but this expertize was wanted by several companies. Eight of nine companies thought it would be useful to increase cooperation with universities and/or research teams. There are different decision-making forums in different companies that decide on changes or implementation of new approaches and methods. Academic knowledge dissemination, implementation and need of (external) support therefore must be adapted to varying conditions in companies in order to be utilized to a much larger extent. Direct communication and local abutment is crucial. Improvement proposals were developed for how to support dissemination and implementation of new knowledge. These were:1.Compilation of easy to read summaries (including contact persons) distributed by research institutes and others conducting research, which companies could subscribe to (see 5. below).2.Innovation/competence centers (knowledge transfer offices) for collaboration/networks between SMEs, universities and research centers of various kind; financing and consulting services for exploitation of research results including specialist staff to help identify and manage relevant knowledge with business potential. 3.Additional time and budget at the end of research programs intended for further dissemination of results and implementation assistance.4.Targeted seminars and work-shops.5.A web portal including useful information of latest research publications, upcoming work-shops, projects and others of interest.6.E-learning for introduction and training in new working methods, tools and others of importance for knowledge transfer before implementation.For all proposals a clear responsibility should be agreed and decided.

How do manufacturing companies acquire new knowledge? - Examples from nine Swedish companies.

- Experience has shown that new research does not reach out to companies and organizations as desired. Thereby many improvement opportunities, increased profitability and competitiveness are probably missed. In order to investigate the underlying causes an interview study in Swedish companies was made. The results showed different reasons in large and smaller companies. The overall conclusion was that dissemination of academic knowledge and associated need of (external) implementation support must be better adapted to varying conditions in companies.
