A simulation based guide to machinability assessment

Important results from the project

Machining plays an important part in the automotive industry. The project´s aim is to create a digital guide to quickly assess the machinability of the incoming workpiece materials. The machinability guide predicts cutting forces, chip formation and tool wear during different cutting speeds and feed for two different demonstrators. The prediction tool is a valuable basis for cutability and further model development.

Expected long term effects

Through the digital model-based machinability guide, the project primarily supports "flexibility and quality", for early decisions, and "shortened lead times". The milestones deal with increased knowledge in cutting machining through new material models, implementations for calibration and validation of cutting processes. The dissemination of knowledge has taken place through international journal publications and conference papers. A doctoral degree and a licentiate degree have been completed within the framework of the project.

Approach and implementation

The project is based on the collaboration between Volvo AB, VCC, Sandvik Coromant and Scania CV together with Chalmers and KTH. We have identified and studied a number of turning and milling demonstrators that combine "material modeling", "material science" and "structural dynamics" to describe the cutting process via the cutability guide. Milestones and deliveries apply to both methodology and competence development.
