Several approaches are explored and developed to improve the contouring accuracy in CNC machines. A tuning procedure is proposed to tune the gains so as to achieve matched axial dynamics. The contouring accuracy for both linear and circular contours can be significantly improved. For circular contours, the radial errors resulting from the limited bandwidth of the axial dynamics can be further reduced by feedforward compensation. A two-stage stiction compensation scheme is proposed to reduce or eliminate the contour errors caused by stiction. A model-based Taylor series expansion error...

Transnational Asian America: Literary Sites and Transits examines the diasporic and transnational aspects of Asian American literature and asserts the importance of a globalized imaginary in what has been considered an ethnic subgenre of American literature. The thirteen essays in this volume engage works of prose and poetry as aesthetic articulations of the fluid transnational identities formed by Asian American writers who move within and across national boundaries. With its emphasis on the transmigratory and flexible nature of Asian American literary production, the collection argues for...
