Abstract
The dry drilling process presents a major challenge due to the high temperature values. A finite element model created on Abaqus is used to simulate the temperature on the workpiece. This model considers the hole already machined and a move source of heat. The heat flux to the workpiece is modeled as non-uniform in space and time. In this study, experimental tests are conducted on 1020 SAE steel workpiece and the temperatures are measured at different points. The inverse procedure based on particle swarm optimization (PSO) is used to minimize the error between the measured and simulated temperatures. The coefficients of the heat flux to workpiece and the associated error are presented.
