    • Manual zero adjustment of a tracer head and adjustment of differential amplifiers for the tracer head are eliminated by a step of storing the outputs of differential amplifier circuits as zero-point offset amounts while maintaining the tracer head in a non-contact state, a step of successively maintaining the tracer head in a first and a second state, and while doing so, storing first and second coordinates of the tracer head in the first and second contact states, together with first and second amounts of displacement compensated for by the zero-point offset amounts, a step of calculating and storing gains of the differential amplifier circuits on the basis of the first and second coordinates and the first and second amounts of displacement compensated for by the zero-point offset amounts, and a step of effecting tracing control through the use of the stored zero-point offset amounts and gains. These steps are carried out under control of a processor.

    • In tracer control equipment which controls the relative feed rate between a tracer head (1) and a model by controlling a motor (12X to 12Z) according to a displacement signal (.epsilon..sub.x to .epsilon..sub.z) from the tracer head, a deceleration control circuit (18) is provided to perform deceleration control corresponding to the configuration of the model at a jerk point thereof.

    • In a tracer control system in which tracer head control is switched over from a quick feed mode to a deceleration mode of operation to alleviate a shock when the stylus of the tracer head contacts the model, the amount of change in the configuration of the model at a profiling start point is detected to control the point of switching over the quick feed mode to the deceleration mode of operation for the next profiling start point in accordance with the detected value, thereby to ensure that the above mentioned mode switching is always accomplished at substantially a constant position relative to the profiling start point on the model surface so as to shorten the profiling time.
