In-process monitoring of microscale grain protrusions by tracing impulse-discharge energy related to thermal transmission balance on diamond cutting interface

Stable ground surface depends on abrasive grain protrusions, but it has no way to monitor the wheel topographical state during grinding. Generally, the charge coupled device (CCD) monitoring is employed to on-machine measure 2D grain protrusions, but the whole wheel micro-topography has not been recognized in-process. In the electro-contact discharge (ECD) truncating of diamond wheel, a thermal transmission balance on diamond cutting interface...
