摘要:
An automatic positioning apparatus comprises a smoothing means. The smoothing means is adapted to connect smoothly a 3-dimensional path based on the preceding and succeeding four taught points irrespective of a straight line or a curved line, while correcting a driving system with a delay of a system of a means being controlled, thereby to achieve a control in consideration of not only inertia but also a response characteristic.

A method of determining an adaptive tool path for additive deposition to an aerofoil having a leading edge, a trailing edge and suction and pressure surfaces extending between the leading and trailing edges, the method comprising the steps: providing an aerofoil with a deposition plane; determining for the deposition plane points corresponding the leading edge, the trailing edge and the centre of a circle constrained by both the suction surface and the pressure surface when they are at their greatest distance apart; determining the position of the centre point of a circle the edge of which passes through the deposition plane points; determining a trailing edge reference line extending from the centre point of the circle through the trailing edge point, a leading edge reference line extending from the centre point of the circle through the leading edge point and one or more mid reference lines extending from the centre point of the circle through one or more mid reference points between the leading edge point and the trailing edge point; trimming each mid reference line to the bounds of the suction surface and pressure surface and determining the length of each mid reference line; applying an adaptive factor to the length of each mid reference line to provide an adaptive point for each mid reference line; determining an spline extending through the leading edge point, the trailing edge point and each adaptive point; and traversing a tool along the spline or a path offset from the spline by a predetermined factor.

In order to suppress fluctuations in specific components of posture angle in a target coordinate system while maintaining the position of the leading edge of the wrist, the velocity of movement of the leading edge of the wrist, and the permissible velocity of the shaft during velocity suppression, an articulated robot which moves while calculating the position in interpolated points on a teaching path, the posture and the angles in each axis is provided, wherein a judgment is made as to whether the velocity of the wrist shaft exceeds a permissible limit, and if the permissible limit is exceeded, a plurality of candidates for angle of the wrist shaft that maintain the velocity within permissible limits are calculated, and the candidate with the minimum fluctuation in the specific component of the posture angle of the weld line coordinate system is selected from said plurality of candidates and made to serve as the angle of the wrist shaft, the angles of other shafts that correspond to this angle are recalculated and made to serve as the subsequent interpolation point, and the articulated robot is driven.

Das Verfahren erlaubt es, sowohl translatorisch und/oder rotatorisch bewegte als auch unbewegte Werkstücke (W2) mit ortsfesten oder mobilen Robotern (R2,R3,R) zu bearbeiten. Dabei wird die Eigenbewegung des Werkstücks (W2) programm-, steuerungs- und regelungstechnisch vom Roboter (R2,R3,R) berücksichtigt. Die für die Technologieanwendungen notwendige Bahntreue und Bahngeschwindigkeit wird am bewegten Werkstück (W2) eingehalten. Das Steuerungsproblem wird transformatorisch über eine Kettung von Koordinatensystemen (ROS,KS1,KS2,KS3,ZAS) gelöst. Wesentlich ist, daß die Gesamttransformation über Parameter (VBE1...n, ZA1...n) je nach Systemkonfiguration vom Anwender frei projektierbar ist.
