Abstract
A numerically controlled sewing machine for controlling the movement of a workpiece holding means according to a program made on the basis of a basic standard size of a basic standard piece and the shape of a basic standard seam to be formed on the basic standard piece. The numerically controlled sewing machine includes detecting means for detecting the first difference between an actual size of a workpiece to be sewn and the basic standard size, and for dividing the first difference by two, size selecting means capable of manually selecting a size close to the actual size from among the basic standard size and a variety of standard sizes predetermined in a given increment, value generating means for generating a half value of the second difference between the size selected by the size selecting means and the basic standard size, compensating means for compensating the length necessary to feed the workpiece from a loading station to a sewing station by summing up a half value of the first difference, a half value of the second difference, and a feeding length predetermined on the basis of the basic standard piece, stitch change means for changing the number of stitches to be formed in the workpiece according to the second difference.
