Model and method for the determination and distribution of converted energies in milling processes (A02)

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

The specific cutting forces generated in the process and the distribution of the resulting heat loss are influenced in many cases today by the use of cooling lubricants. This usually also has a reducing effect on the wear rate. In the 3rd phase of the subproject, the developed energy model and methods for recording and balancing the energy conversion in the milling process are to be extended by the influence of cooling lubri-cant and tool wear. The aim is to predict the temperature fields in the tool and the heat flow distribution in the process. For this purpose, the influence of cooling lubricant on the heat flow distribution in the cutting zone is fundamentally investigated and modelled. Initially, analogy tests in the form of interrupted turning tests are planned in order to validate the findings and models gained on a real, cooled milling process.
