Three-Axis Contouring Control Based on a Trajectory Coordinate Basis

抄録

This paper presents a servo control method for three-axis machine tool contouring applications The proposed contouring system operates its control efforts in a trajectory coordinate basis that is moving along the tool path trajectory, rather than the convensional XYZ coordinate basis.With the proposed method, an efficient control of the concerned error components that are defined along the tool path can be achieved.
