Estimation of Distribution of Moving Heat Source during Milling of AISIH13 by Inverse Heat Conduction Method

somayeh davoodabadi farahani
This study presents an inverse heat transfer method to estimate the local heat flow into the workpiece during milling of AISIH13 with considering a 3D- thermal model. Conjugate gradient method is used as an inverse solver.Moving point heat source and moving plane heat source with different the heat source velocity is considered. Results indicate a good agreement between the experimental and estimated data with an average root mean square error less than 0.2 °C. Heat flow distribution is a function of the heat source geometry, cutting speed and feed-rate. Temperature distribution is a weak function of the geometry of moving heat source.
Keywords: Milling, Inverse method, moving plane heat source, moving point heat source, Cutting temperature.
