Model and method for the determination and distribution of converted energies in grinding processes (A03)

• Subject Area: Metal-Cutting and Abrasive Manufacturing Engineering
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 174223256

The result of the 1st and 2nd phase is a parameterized process model providing a quantitative description of the heat fluxes into the components involved in the grinding process - tool, workpiece, cooling lubricant and chips. The influence of tool wear and cooling lubricant supply on the heat fluxes was not taken into account yet. As a result, the model becomes inaccurate as tool wear increases and the coolant supply changes. The objective of the 3rd phase is therefore to investigate the influence of tool wear and coolant supply on the heat flux in grinding and to extend the process model by these influencing variables.
