Precision cutting process machine and precision cutting process method

Abstract

A precision cutting process machine aligns a workpiece to be subjected to a precision cutting process by a continuously rotating cutting tool relative to the cutting tool, and cuts the work into a predetermined pattern so as to form fine grooves at a predetermined pitch by a continuous cutting processes. The machine includes a main body base portion and an up-and-down moving table driven in the up-and-down direction with respect to the main body base portion. The cutting tool, which is arranged on the up-and-down moving table, sets a plane formed upon rotation of the cutting tool on a plane along the back-and-forth direction of the main body base portion and is continuously rotated; back-and-forth moving table is driven in the back-and-forth direction with respect to the main body base portion, a right-and-left moving table is fixed on the back-and-forth moving table and driven in the right-and-left direction with respect to main body base portion, a holding device is arranged on the right-and-left moving table for detachably holding the work, and a measurement device is arranged on the up-and-down moving table for measuring dimensions of the workpiece in the up-and-down and right-and-left directions. In order to perform the cutting process of the workpiece held by the holding device, the moving amount in the up-and-down direction of the cutting tool, which is arranged on the up-and-down table and continuously rotated, is measured by the measurement device while the moving amount, in the right-and-left direction, of the workpiece held by the holding device on the right-and-left moving table is measured by the measurement device.
