“…Castelino et al [44] model a machining tool path problem as a regular GTSP which is subsequently transformed into a TSP by doubling the number of nodes and redefining some arcs. This TSP is then solved using the Lin-Kernighan heuristic of Helsgaun [85] when no precedence constraints are present, or by the branch-and-cut approach for the SOP of Ascheuer et al [24] when precedence constraints are present.…”

This paper presents a review of the literature on generating cutting paths for laser cutting machines. Firstly, the cutting path problem is defined including all relevant technical side constraints which exist plentifully in laser cutting. Secondly, a former classification method is updated to include all types of cutting path problems. Thirdly, a comprehensive review of solution methods and related applications is presented. Throughout the literature review, trends in research in cutting path generation and interesting areas for future research are identified.

“…The trajectory planning refers to the generating the position commands, velocity and acceleration of all degrees of freedom of a robot at each sampling time. Proper formulization of the trajectory enables further optimization so that the energy consumption, the forces and torques transmitted to the joints/arms and the time of machining are minimized [16,17]. It is worth mentioning that a trajectory can drastically affect the quality of the machined work piece, time, cost and the life time of the tool at the end effector of the robot.…”

In this paper, a CAD-based trajectory planning scheme for parallel machining robots is introduced using the parametric Non-uniform rational basis spline (NURBS) curves. First, a trajectory is designed via a NURBS curve then, a motion scheduling architecture consisting of time-dependent and constant feedrate profiles is advised to generate the position commands on the represented NURBS curve as the tool path. Using the generated commands, the inverse kinematics is elaborated to obtain the joints motions of the parallel machining robot. This paper investigates the NURBS trajectory generation for a parallel robot with 4(UPS)-PU mechanism as the case study. In order to evaluate the effectiveness of the proposed method, the inverse kinematic results for the parallel machining robot of 4(UPS)-PU is compared with the simulation results obtained from the CATIA software. The results confirmed that the proposed trajectory planning scheme along with the advised motion planning architecture is not only feasible for the parallel machining robots but also yields a smooth trajectory with a satisfactory performance for all the joints.
