Abstract: In this study, nylon tubes were welded to nylon plaques using laser transmission welding. A conical mirror inserted inside the tube was used to guide the laser beam along the weld path around ...

Abstract: Industrial robots may not be off-line programmable, unless their accuracy is improved by a suitable calibration procedure. However, proper calibration is a time-consuming and expensive procedure ...

Abstract: Most industrial robots cannot be off-line programmed to carry out a task accurately, unless their kinematic model is suitably corrected through a calibration procedure. However, proper calibration ...

Abstract: A new robot kinematic calibration procedure is presented. The parameters of the kinematic model are estimated through a relationship established between the deviations in the joint variables and ...

Abstract: This paper addresses the reinforcement of photopolymers, through the addition of short glass fibers, for Rapid Layered Composite parts Manufacturing (RLCM). Novel designs for an (external) ...

Abstract: Significant attention has been paid recently to the topic of robot calibration. To improve the robot’s accuracy, various approaches to the measurement of the robot’s position and orientation ...

Abstract: In this paper, we present a rapid manufacturing process for the layered fabrication of polymer-based composite parts using short discontinuous fibers as reinforcements. This process uses a ...

Abstract: Laser transmission welding (LTW) is a relatively new technology for joining plastic parts. This paper presents a three-dimensional (3D) transient thermal model of LTW solved with the finite ...
