An Experimental Investigation of Temperatures in Chip Formation

  • H. T. Young


The results of an experimental investigation on chip temperatures by infrared thermo-tracer are presented. The experimental data are seen to seriously disagree with the boundary conditions at the interface of chip/work free surface that are made in previous analytical models. Correction measure is taken and a comparison of the derived temperatures along the shear plane with previous results is made. It is also found that the temperatures directly taken on the chip back can be best used for verification of previous models. A scheme is developed for determining the tool/chip interface temperatures from the measured data. Results indicate that a simplified model with assumed constant shear plane temperature is sufficient in evaluating the maximum temperature on the tool/chip interface at higher cutting speeds.
