Computation of the thermal field in tools during machining processes

This paper deals with the modelling and computation of the thermal field inside turning tools during machining processes. The analysis is developed for the parabolic heat equation both in the transient and steady case as well as for inverse-type problems where some information on the solution is obtained from experimental data. Some numerical simulations are performed and a discussion on some research perspectives is proposed.

Dynamic Analysis of Production Processes by Planned Experiments

An experimental investigation was performed on a plant providing selected raw material to ceramic and tile industry. Sizable single and combined effects of a number of factors were observed, and valuable information relevant to process planning and control was obtained, leading to improved production rate and energy conservation. Dynamic aspects of process mechanics were also investigated, since under given conditions vibration induced fatigue loading affects critical component integrity. Dependence of critical spectral components from process parameters was therefore investigated; data obtained include maps of safe operating regions within a broad sample space, allowing trouble free operation without impairing production rate.
