This work aims to provide a solution to minimize the task completion duration for planar tasks by in-troducing kinematic redundancy. An example setting of a redundant planar mech-anism is considered and an algorithm developed for resolving redundancy order to minimize task completion duration is discussed based on this mechanism.Conference Object Design and Analysis of a Parallel Mechanism for Kinematically Redundant Hybrid Planar Laser Cutting Machine(2014) Dede, Mehmet İsmet Can; Gezgin, Erkin; Kiper, Gökhan; Mastar, Ercan; Sığırtmaç, Tayfun; Uzunoğlu, EmreConventional planar laser cutting machines cannot achieve high accelerations, because the required precision values cannot be achieved due to the high inertial loads. Machines configured as kinematically redundant mechanisms are able to reach 5-6 g acceleration levels since they include a parallel mechanism with a smaller workspace which is exposed to smaller inertial loads. The study presented in this paper focuses on the design of a parallel planar mechanism to be integrated to the main axes of conventional planar laser cutting machines to achieve higher accelerations of the laser head up to 6 g. Parallel mechanism’s conceptual design and dynamic balancing studies are provided along with the joint clearance effect on precision due to having more joint structures.
