Abstract	Based on the mathematical model describing the third-order approximation of the cutter envelope surface according to one given cutter location (CL), a tool positioning strategy is proposed for efficiently machining free-form surfaces with non-ball-end cutters. The optimal CL is obtained by adjusting the inclination and tilt angles of the cutter until its envelope surface and the design surface have the third-order contact at the cutter contact (CC) point, which results in a wide machining strip. The strategy can handle the constraints of machine joint angle limits, global collision avoidance and tool path smoothness in a nature way, and can be applied to general rotary cutters and complex surfaces. Numerical examples demonstrate that the third-order point contact approach can improve the machining strip width greatly as compared with the recently reported second-order one.
