     the present work propounds an inverse method to estimate the heat sources in the transient two-dimensional heat conduction problem in a rectangular domain with convective bounders. the non homogeneous partial differential equation (pde) is solved using the integral transform method. the test function for the heat generation term is obtained by the chip geometry and thermomechanical cutting. then the heat generation term is estimated by the conjugated gradient method (cgm) with adjoint problem for parameter estimation. the experimental trials were organized to perform six different conditions to provide heat sources of different intensities. this method was compared with others in the literature and advantages are discussed.
