Geometric contour following for scanning control in SFF application is used to
refine the boundary ofthe parts for increasing the accuracy or to develop the capability to
arrange various scanning directions and paths for improving the part strength. The scanners
must be driven to follow the prescribed path as fast as possible, limited by available
torques. In this paper the minimum time optimal control problem with specified path and
limited control torque is formulated. According to the trade-off between various
requirements, a control strategy is studied.Mechanical Engineerin
