RISLocal Contact Stiffness Detection for Nondestructive Testing Based on the Contact Resonance of a Piezoelectric Cantilever
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the field of nondestructive testing (NDT), a suitable defect identification parameter plays an important role in evaluating the reliability of structures or materials. In this work, we proposed a NDT method which detects ...
An Equivalent-Plane Cross-Coupling Position Control for Contour-Accuracy Improvement in Three-Axis Free-Form Contour Following Tasks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To reduce the contouring errors in computer-numerical-control (CNC) contour-following tasks, the cross-coupling controller (CCC) is widely researched and used. However, most existing CCCs are well-designed for two-axis ...
