In five-axis machining, multipoint tool orientation has the merit of getting a wider strip width. However, large computing time restricts its application. In this paper, for machining free-form surfaces by toroidal tools, a highly efficient and conve

Blades are affected by clamping, cutting forces, and residual stress, thus resulting in warping and distortion because of the thin wall and free surfaces. In this paper, a new process for the control of machining distortion is proposed to eliminate s
