    摘要: A tracing control system for tracing a groove counter can easily measure the groove contour formed on a three-dimensional model surface. A tracer head is provided with a stylus having a size enabling the stylus to slide in a groove formed on the model surface in the state that the stylus receives a load from three axial directions. Amount of displacement sensing means senses the amount of displacement of the stylus. Displacement vector calculation means calculates the displacement vector of the stylus based on the sensed amount of displacement of the stylus. Movement control means controls the positional movement of the tracer head so that the displacement vector is equal to a predetermined vector value at all times. Position sensing means senses the present position of the tracer head. Data creation means creates digitized data based on the sensed present position of the tracer head and the amount of displacement of the stylus.

    摘要: According to the method of machining on ultra-precise surface of revolution (240) on a workpiece (204) held in position by means of a workpiece-carrier spindle assembly (1) whose spindle is mounted on a spindle slide (202) by means of active magnetic bearings, the natural frequencies of the bearing servo-control are adjusted to values which are less than about 80 Hz, and the speed of spindle rotation is adjusted to a value of about 20 Hz to about 75 Hz, the radial and axial positions of the spindle are selectively modified about a nominal position by applying variable reference voltages to the circuits controlling the magnetic bearings, said voltages being varied as a function of control signals which are delivered as a function of the position of the tool (207), and displacement of the spindle slide (202) is inhibited so long as the control signals are less than predetermined values lying within the dynamic range of the magnetic bearings. The invention is particularly suitable for machining atypical surfaces of revolution by copying a master template.

    摘要: Provided is a tracer control method in a master-slave type tracer system having first and second tracer units in each of which a tracer controller (TCC.sub.1, TCC.sub.2) generates velocity commands (V.sub.x, V.sub.y, V.sub.z) along respective axes by using a detection signal generated by a tracer head (TC.sub.1, TC.sub.2), motors (XM.sub.1, YM.sub.1, ZM.sub.1 ; XM.sub.2, YM.sub.2, ZM.sub.2) provided for respective axes are driven on the basis of the velocity commands and a workpiece (WK.sub.1, WK.sub.2) is subjected to tracer machining conforming to the profile of a model (MDL), tracer machining being performed by tracing a model (MDL.sub.1) with the tracer head (TC.sub.1) on the first tracer unit side and providing the second tracer unit with a move command on the basis of the tracing. In the tracer control method, the first tracer unit (TCC.sub.1, TCM.sub.1) produces the velocity commands (V.sub.x, V.sub.y, V.sub.z) in digital form to drive the motors (XM.sub.1, YM.sub.1, ZM.sub.1 ) for the respective axes, monitors a current position of a movable element, and sends a distance travelled along each axis during a predetermined time interval as a digital move command to the second tracer unit (TCC.sub.2, TCM.sub.2). A pulse distributor (PDC.sub.2) of the second tracer unit performs a pulse distribution calculation on the basis of move command data received as an input from the first tracer unit, thereby to control the motors (XM.sub.2, YM.sub.2, ZM.sub.2) of the respective axes on the side of the second tracer unit.
