    摘要: Die Erfindung betrifft ein Verfahren zum Bewegen von Führungsköpfen (7, 8), ggf. eines Werkstücks (5), einer Drahterosionsmaschine entlang jeweils einer Drahtführungsbahn (TD), wobei mittels eines zwischen den Führungsköpfen verlaufenden Schneiddrahtes (1) eine Kontur in das Werkstück (5) geschnitten wird und der durch die Bauchung des Schneiddrahtes (1) entstehende, tatsächliche Schleppfehler (S) kompensiert wird, indem die jeweilige Drahtführungsbahn (TD) gegenüber einer durch wenigstens eine Umrißkurve (UK) dargestellte, zu schneidende Kontur korrigiert wird, dadurch gekennzeichnet, daß zum Korrigieren der jeweiligen Drahtführungsbahn (TD) ein Schleppfehlerkorrekturvektor ( S B ¯ ) berechnet wird, wobei dessen Betrag (| S B (t) ¯ |) aus den momentanen der Erosion zugrundeliegenden Erosionsparametern und dessen Richtung, insbesondere den Winkel (α(x)) zwischen dem berechnetem Schleppfehlerkorrekturvektor ( S B ¯ ) und der Tangente an einen Punkt x der Umrißkurve (UK), aus den momentanen der Erosion zugrundeliegenden Erosionsparametern und/oder aus der Geometrie der zu schneidenden Kontur berechnet wird. Außerdem betrifft die Erfindung eine zum Durchführen des Verfahrens geeignete Drahterosionsmaschine.

    摘要: A digitizing method which controls the movement of at least one axis (X- or Y-axis) by the numerical control based upon the passage data, which controls the movement of another axis (Z-axis) by the profile control, and which monitors the current positions of the axes in order to obtain three-dimensional data on an object. A numerical controller (101) performs numerical control based on NC data supplied from an NC tape (106) to move a tracer head (105) in the X-and Y-directions. A profile controller (102) performs the control relying upon displacement components (εx, εY, εz) of the axes generated by the tracer head, to produce a speed instruction V z of the Z-axis, and to move the tracer head in the direction of Z-axis. The numerical controller (101) counts the number of pulses (F z ) generated every after a motor (M z ) that drives the profile control axis (Z-axis) has made rotation of a predetermined angle, and obtains the current position of the profile control axis. The numerical controller further obtains an instruction position of the numerical control axes (X-, Y-axes) using the passage data, and subtracts servo delay amounts (E x , Ey) which are the contents of error registers (ER . , ERy) from the instruction position, in order to obtain a current position expressed by a mechanical position. Thereafter, the current positions of the axes represented by mechanical positions are stored in a memory (101b) every after a predetermined period of time.

A numerical controller (101) performs numerical control based on NC data supplied from an NC tape (106) to move a tracer head (105) in the X- and Y-directions. A profile controller (102) performs the control relying upon displacement components (epsilonX, epsilonY, epsilonZ) of the axes generated by the tracer head, to produce a speed instruction VZ of the Z-axis, and to move the tracer head in the direction of Z-axis. The numerical controller (101) counts the number of pulses (FZ) generated every after a motor (MZ) that drives the profile control axis (Z-axis) has made rotation of a predetermined angle, and obtains the current position of the profile control axis.

    摘要: Machines having a boom or arm pivotally disposed thereon wherein the length of the boom or arm and the angle thereof with respect to a reference plane are adjustable by means of actuators are well known. However, it is extremely difficult, if not impossible, to simultaneously control the actuators in a coordinated fashion to move the end of the boom or arm in a straight line path. In order to overcome this problem, a boom control system for a boom (12) according to the present invention controls the actuators (16, 18) in either of two modes of operation, the first mode of operation comprising independent control over each actuator (16, 18) to afford polar coordinate operation and the second mode of operation comprising synchronized control over the actuators (16, 18) so that the end of the member (12) may be moved in a straight line. Means (34) are provided for manually selecting one of the two modes of operation. Means (110-118) may be provided for calculating the amount of remaining horizontal throw of the boom (12) or arm when a command to move same is issued.

    摘要: An individual section glassware forming machine comprises generating means (29) for generating an electrical command signal which is used to control transfer means (2) of the machine. The transfer means (2) is used for transferring a parison (P) from a blank station (A) at which the parison is formed in an inverted position and presenting the parison (P) in an upright position at another station (B). The magnitude of the electrical command signal varies in accordance with the desired position against time curve for the movement of the parison (P) and is used to operate an electrical or hydraulic servo-mechanism (32; 42) for controlling the movement of the transfer means (2).
