Abstract

In biaxial contour tracking applications, the main concerns are the tangential and the contour errors. This paper presents a tangential-contouring controller to achieve effect and decoupled control of these concerns. The proposed controller is based on a coordinate transformation between the X-Y frame and a tangential-contouring (T-C) frame that is defined along the contour. Experimental evaluation for the proposed controller is conducted on a biaxial positioning table.
