The finish cutter location data were computed using the equidistant offset surface method, and the machining row distances were acquired by the control of the residual height.

This algorithm combines the block Pilot-aided LS channel estimation algorithm with a phase tracking algorithm, which can compensate the phase rotation caused by the residual carrier frequency offset.

Static correction problem is resolved by adopted methods like sand dune curve, interactive refraction static correction, and offset-division surface-consistent residual static correction.
