    摘要: When a non-contact tracing of a configuration of a three-dimensional model is carried out, the measurement axis of a tracer head is controlled to always be facing in an optimum direction with respect to a model surface by controlling the attitude of the tracer head, to thereby create tracing data of the configuration of the model. The tracer head is provided with two non-contact distance sensing units, and a normal vector of the model surface is determined based on a measurement value obtained by sampling tracing data supplied from the tracer head. At this time, the direction of a normal vector is determined from the outer product of surface vectors in a range in which the angle between an axial vector starting from a measurement point of the measurement axis of the tracer head and the normal vector at the measurement point does not exceed 90.degree.. The tracer head is controlled to be rotated in the direction toward a projection obtained by projecting the normal vector on a predetermined plane.

    摘要: A noncontact tracing control system for tracing machining a workpiece through a tracing of the contour of a model without contact. Coordinate values of a plurality of points on the model surface are acquired from measured values obtained by a plurality of times of sampling from two noncontact distance detectors (5a, 5b) provided at a tracer head of a tracing machine (3). A noncontact tracing control system (1) selects three points forming a triangle closest to an equilateral triangle, from among these points. A normal vector is acquired using the coordinate values of the vertices of these three points and outputs a command (SC) for rotating the tracer head (4) in the direction of a projection of this normal vector onto the X-Y plane. This command (SC) passes a D/A converter (17c), is amplified at an amplifier (18c), drives a motor (32c) and rotates the tracer head (4). As the measuring axis of the noncontact distance detectors (5a ,5b) is oriented in the direction most nearly perpendicular to the model surface, the distance thereto can be measured with a high accuracy.

    摘要: A digitizing control device for generating tracing data related to a shape of a model while a tracer head carries out a non-contact tracing of the model shape. The rotation of the tracer head (4) is controlled in accordance with the inclination of a model surface (6), and distance detectors (5a, 5b) measure the distances therefrom to the model surface (6). When the inclination of the model surface (6) is smaller than a reference angle, the control of the rotation of the tracer head (4) is prohibited, to thereby achieve a stable distance measurement, and accordingly, accurate tracing data can be generated by a non-contact tracing of the model surface.
