Abstract :
A new type of touch probe for measuring small optical parts is proposed. The probe is excited by a piezoelectric actuator in sinusoidal waveform. When the vibrating probe touches an object, harmonic components of the vibration appear in the power spectrum of the probe vibration. When the power of the second harmonic exceeds a threshold level, it is judged that the probe touches the object. Measuring force is small enough for measuring the surface of optical parts. The touch probe is mounted on a small CMM controlled by a PC and evaluated its performance by measuring a standard steel ball.
