    A macro-micro mechanism design for laser cutting process
    (MATIMAREN, 2016) Dede, Mehmet İsmet Can; Kiper, Gökhan; Uzunoğlu, Emre
    This paper is organized to provide the novel approaches during the design of a machine to shorten the laser cutting process. Macro-micro manipulation concept is employed for the design of this machine both in the mechanical design and in devising the trajectory planning algorithm. Micro-mechanism design along with its calibration process are also explained since they involve novel approaches in this application domain. Trajectory planning algorithms, which are developed in this work, are discussed based on their applicability to CNC system architecture. Finally, experimental results based on a benchmark workpiece are given and the system design is discussed with respect to these results.

    Development of an R-Cube Based General Purpose Haptic Device System
    (American Society of Mechanical Engineers, 2010) Bilgincan, Tunç; Dede, Mehmet İsmet Can
    A novel 6-Degree-of-Freedom (DoF) hybrid haptic device is presented in this paper. Hybrid mechanism consists of parallel kinematic structure, R-CUBE and a 3-DoF orientation mechanism. In our previous study, the original configuration of the R-CUBE mechanism was investigated. In this work, the original design of R-CUBE is reconfigured as a haptic mechanism and the final mechanism is reoriented in order to equally distribute the gravitational effects to all grounded actuators. Rotational motions of the end-effector are monitored through the 3-DoF orientation mechanism placed on the moving platform of the parallel platform. The design of this haptic device is suitable to reflect forces in translational motions, thus point-type of contact is available for this system. The designed device is manufactured utilizing various types of manufacturing processes, such as wire erosion, laser cutting, milling and turning. Finally manufactured mechanism is integrated with electromechanical components and tested for manipulability.
