摘要:
A lapping machine control system which utilizes a electromechanical probe (13) to generate a signal responsive to the separation of the laps (10, 11), which also represents the thickness of the part (13) being lapped. The separation signal, which is unsuitable for direct control since it is too noisy, is used with a best fit algorithm to estimate the time to reduce the part (13) to the desired thickness, based on the rate of material removal provided by extrapolated line (320) representing the best fit of the lap separation signal. The machining is terminated when the extrapolated line (320) reaches the intercept of time (340) and thickness (330).
