Purpose and goal
The project has addressed challenges in casting and realisation of new cast irons with improved properties and machinability, decision making regarding manufacturing strategies and machinability of materials. Silicon-alloyed compacted graphite iron (CGI) has been demonstrated av new alternative for future engine components. New simulation technique for assessing manufacturing strategies has been introduced. Generic knowledge has been developed when it concerns work material machinability with specific reference to combined materials in advanced components.
Results and expected effects
Solution-hardened CGI has higher strength than current cast irons and better machinability than previous CGI. The simulation methodology for assessing machining strategies has been validated through case studies. The methodology with controlled cutting experiments and FE-modelling is generic and can be applied for new materials in future. The improved understanding regarding material variations among suppliers contribute to their capability in sustainable production and technical seminars have been started. Two PhD exams and one licentiate degree have been accomplished.
Approach and implementation
Specific challenges has driven R&D involving close cooperation between university/institute and companies. Correlation between theory, laboratory studies and pilot studies with/at companies (casting tests, machining strategies studies, machining component-like parts) supports applications with good scientific publication and has been combined with internationalisation and two PhD exams and one licentiate degree. The project has been performed between 1 June 2012 to 30 November 2015 with total budget of 15.47 MSEK, whereof 7.7 MSEK has been the VINNOVA support.
