The automotive industry is continuously developing and finding new ways to respond to the incremental demands of higher safety standards and lower environmental impact. As an answer to weight reduction of vehicles, the combination of boron steel and composite material is being developed along with their joining process, self-pierce riveting. Boron steel is an ultra-high strength material that needs to be locally softened before the joining process. However, the joining process deforms the part. This paper investigates factors affecting the geometrical deformation during the tempering process and lists important phenomena that need to be included when simulating the tempering process.

Det finns en övertygelse om att sättet som vi utvecklar industriarbetet på ger fördelar och konkurrensfördelar som inte går lätt att kopiera! Denna skrift visar hur några av de bästa företagen i Sverige utvecklar industriarbetet för att stärka sin konkurrenskraft och produktion i Sverige. Här är produktion och produktivitet i fokus som samtidigt skapar bra förutsättningar för individen och erbjuder ett attraktivt långsiktigt hållbart arbete. I en grundbild beskrivs gemensamma kvaliteter som företagen eftersträvar att stärka och vidareutveckla. Skriften ger inspiration för att ta fram en gemensam målbild inom det egna företaget för utveckling av industriarbetet som har förutsättningar att skapa fördelar både för företaget och medarbetare. Den innehåller också ett workshopunderlag för att analysera nuläget (bra initiativ, aktuella utmaningar, företagets egna styrkor), för att identifiera och prioritera aktiviteter och ta fram ett underlag till en handlingsplan. Skriften bygger på erfarenheter från  SKF, Scania CV, Alfa Laval Lund, SSAB EMEA, Atlas Copco Secoroc, Skaraverken, Furhoffs Rostfria, Westbaltic Components, Volvo Personvagnar och forskare från olika forskningsfält i Sverige. Studien och denna skrift har genomförts på uppdrag av IF Metall, Teknikföretagen, Swerea IVFs Intressentförening och Vinnova.

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. Copyright © 2009 by ASME.
