    摘要: A rotating body tracing control apparatus which performs a tracing while rotating a model and a workpiece. A plurality of point coordinates (P1 or P10) are set on the outer peripheral surface of the model (6), which points depend on a position of the central axis of the rotation and the angle of the rotating axis of the rotation, and a tracing is executed by using a line connecting the individual points (P1 to P5, P6 to P10) as a potential line. Therefore, even when tracing a model, such as a groove of a cylindrical cam having a shape which varies along the central axis of a rotating body, only the groove region can be set around the potential line, and thus the tracing time can be shortened and the groove alone can be treated with a high accuracy.

    摘要: A tracer control system which performs tracer control based on a displacement signal from a tracer head tracing the surface of a model and is equipped with the function of freely setting the infeed of a cutter for machining a workpiece. The tracer control system is provided with a first drive system for feeding the tracer head in the Z-axis direction, a second drive system for feeding the cutter head in the Z-axis direction, first and second position detectors for detecting the positions of the tracer head and the cutter head in the Z-axis direction, and a superimposing circuit for superimposing on each other a position detection signal from the first position detector and an infeed command signal for setting the infeed of the cutter head. The cutter head is fed by the second drive system in the Z-axis direction so that the difference between output signals from the superimposing circuit and the second position detector may be reduced to zero.

    摘要: In a system which performs tracer control by calculating the direction and the velocity of tracing through utilization of signals from a tracer head tracing the model surface, there are provided an input unit for entering data defining the tracing operation, a memory for storing the data and processor for reading out the data from the memory to control respective parts of a control device. Data concerning clamp tracing is read out by the processor to change the clamp level by a predetermined value for each working, thereby performing repetitive clamp tracing.

    摘要: The movement of a template past a stylus is controlled by furnishing desi velocity signals to first and second motors driving the template along two mutually perpendicular axes. Two wheatstone bridge strain gauge arrangements, one for each axis, and energized by quadrature voltages furnish signals which are combined in a summing amplifier to yield a signal having an amplitude and angular deflection corresponding to that of the stylus. The signal is rectified yielding a signal corresponding to the amplitude of stylus deflection and is further used to synchronize a sawtooth wave generator in accordance with the angle of deflection. The sawtooth wave output and the amplitude signal output are compared and when equal set a monostable multivibrator which closes two switches each sampling the output of one of the quadrature voltage generators energizing the strain gauges. Each of the so sampled voltages is applied to a potentiometer the output of which controls a corresponding one of the drive motors for the template.
