... in Fig. 3a a , the heat carrier consisting of HWS and HBS carriers moves at the drilling feed rate to simulate the heat conduction to the workpiece during drilling. Since the heat carrier and workpiece have different meshes, the inconsistent mesh sizes in hole surfaces may cause the elements...

... to estimate the transient thermal load and the thermal deformation of the structure in real-time. To satisfy the stringent accuracy and stability requirements of the control system, a new inverse heat conduction problem IHCP solver is developed. This solution is capable of including the inertia effect...

The full three-dimensional nonlinear transient heat conduction equation is solved numerically using a control volume approach to study these nonlinear effects on cutting tool temperatures. The extremely small size...
