Abstract
Disclosed is an improved method of cutting and separating a bent board into individual small divisions. Prior to the cutting and separating of the board into the individual chips the board is cut and separated into two or more pieces each large enough to have a reduced bend, compared with the bend of the board. Thus, each large division can be put and fixedly held on the chuck table of a cutting machine in stable condition, thus permitting the smooth, stable cutting of the large division into final small divisions.
