In the lapping process, what is charged?

The workpiece
The lubricant
The lap
The machine

The correct answer is: The lap

In the lapping process, the lap is the component that is charged. Lapping is a precision finishing process where two surfaces are rubbed together with an abrasive between them, which can include a lap made from a soft material. To enhance the effectiveness of this process, the lap is often charged with an abrasive material. This can involve applying a fine abrasive compound that helps to remove material from the surface of the workpiece, ensuring a smooth and precise finish. Charging the lap is crucial because it increases its abrasive action, allowing it to effectively achieve the desired surface finish. The lap itself typically has a structure that can hold this abrasive, which is integral to its function in the lapping process. Typically, the workpiece and the lap work together, but it is specifically the lap that is prepped or "charged" with abrasives to facilitate effective material removal.
