Abstract:
1. A measurement system for an automated lapping system, the measurement system comprising: a moveable frame configured to be controllably positioned proximate to a lap work product; a non-contact measuring device coupled to the moveable frame and configured to measure a surface of the lap work product; a lapping robot configured to move proximate to and lap the lap work product, the lapping robot not attached to the moveable frame and the non-contact measuring device; a first control component configured to control a movement of the lapping robot; a second control component configured to receive measurement data of the surface of the lap work product from the non-contact measuring device, and to provide first control signals to control a movement of the moveable frame relative to the lap work product, and a second control signal to control a movement of the non-contact measuring device laterally or vertically along the moveable frame, wherein the first control component and the second control component are further configured to coordinate the movement of the lapping robot and the non-contact measuring device so that the lapping robot pivots in a first direction to lap a first surface area of the lap work product while the non-contact measuring device simultaneously moves in a second direction to measure a second surface area of the lap work product.
