This paper presents simulation techniques to further study the tool temperature distribution curve previously reported. The simulation setup employed a miniature oxyacetylene torch incorporated with a pulse control mechanism. The experimental simulation yielded similar temperature distribution curves to those obtained in the cutting experiments. The temperature distribution curve obtained by digital computer simulation shows a good agreement with that obtained in the cutting experiments. An analysis of the effect of the removed material near the tool tip was made using the numerical method. The result indicates that the material removed up to a tool tip thickness of 0.085 in., which was used in the previous paper, does not show significant effect on the temperature responses.
