Measurements of heat input generated in the plate cut by a laser cutting and a plasma cutting have been made for investigating a predictive equation. The heat input of cutting is called as the residual energy in the cutting field and is important factor for controlling the deformation generated through a thermal cutting process. The total energy needed for the thermal cutting was studied by many researchers and the predictive equation of the total energy was proposed by Wells. However the equation predicting the residual energy was not studied. The equation for the residual energy is derived from modifying Wells equation. By comparing the experimental data with the prdicted values, it is shown that the proposed equation is applicable to the evaluation of the residual energy.
