Summary
The following project will investigate in details the mechanics and microstructural aspects associated with large-strain plastic flow in high-speed machining of low diffusivity heat-resistant superalloys and their impact on tool degradation and machined surface integrity. The following objectives have been defined : - to develop experimental methods for the in-process characterisation of tool-chip/tool-workpiece contact conditions in high-speed machining. - to develop In-situ/In-operando experimental methods for the investigation of tool/coating degradation mechanisms (e.g. diffusion, chemical wear, oxidation) under High Pressure-High Temperature. - to apply Synchrotron-based X-ray analysis methods to characterise the impact of tool material/coating/geometry design and process parameters on the surface integrity of machined workpiece. The result from this project will provide Seco Tools with scientific knowledge to further develop a robust science-based technical competence platform to design and optimise tooling materials and coating solutions with enhanced properties in order to achieve a predictable machining performance.
Popular science description
Sandvik Machining Solutions (SMS) is a business area of the Sandvik Group, which Seco Tools is a part of. SMS holds a world leading position in the metal cutting tool industry sector with world market share of 35% and plays also an important role in the Swedish manufacturing sector where the demands for increased productivity requires the development of high performance products and advanced metal cutting solutions for a more efficient component manufacture. In order to meet these challenges and remain competitive on the market, robust knowledge-based competence platforms are needed for developing new cutting tool geometries, tool and coating materials. In the latter, the optimisation of a particular material design and synthesis route for the tool/coating material remains a crucial step that often determines the mechanical properties and wear performance of the final product. The proposed research represents an important step in this direction where accordingly a competence platform utilising advanced “in-process” material characterisation will be developed for studying in details the cutting behaviour and tool degradation properties of ultrahard cutting tool materials at elevated temperatures and pressures approaching those typically encountered in metal cutting operations. The research work will be carried out at the department of Mechanical Engineering at Lund University and will also leverage on the proximity to large scale infrastructure such as MaxIV laboratory for industrial utilisation of synchrotron based radiation techniques for material characterisation.
