Abstract

The cutting forces in drilling significantly affect the accuracy and quality of hole machining. The unbalanced radial component of the cutting force increases the hole diameter and decreases its accuracy. In machining composites, extreme axial cutting force separates the layers and impairs hole quality. Accordingly, there is a pressing need to predict the cutting forces in drilling. In the present work, the cutting force and torque in the drilling of 6061-T6 aluminum alloy are simulated by the smoothed particle Galerkin (SPG) method. Comparison shows that the results obtained are in good quantitative agreement with other calculations and experimental data.
