Abstract: We present a novel 4-DOF (degrees of freedom) parallel robot designed for five-axis micromachining applications. Two of its five telescoping legs operate simultaneously, thus acting as an extensible parallelogram linkage, ...

Abstract: Abstract. We derive closed-form solutions to the direct-kinematics problem of a family of three and six degrees-of-freedom 3-X_PS parallel manipulators. In this class, the direct kinematics reduces to the classical ...

Abstract: The telescoping ballbar is a versatile and easy-to-use error identification instrument for machine tools. The ballbar movement trajectory used while machining is limited to acquiring a large circular arc for positioning ...
