The study on energy fraction of flowing heat energy into workpiece using inverse heat conduction method (In the case of triangle shape of heat flux distributions)

摘要

The thermal energy that arose in the grinding surface is distributed and flown into workpiece and grinding wheel, etc. during the grinding manufacturing. Especially, there is widely dispersed from degree of uncertain of the thermometry with 30～90% at this thermal energy distribution fraction of workpiece side. In this study, taking account oxidized heat in the grinding formation plane into the part of heat source, we analyzes the heat energy flux in inverse problem using measured temperature values by the thermometry (25 μm C-A) in workpiece. It is reported that it tried to accurately decide the thermal energy distribution fraction to the workpiece for all thermal energy with or without oxidation heat flow rate.
