<P>PROBLEM TO BE SOLVED: To provide a sewing machine which can easily generate sewing data with little position gap and prevents a deterioration of sewing quality. Ž<P>SOLUTION: With the method for generating sewing speed data of a sewing machine 100, a holding frame which holds textile of a workpiece is provided, and the holding frame synchronizes with vertical motion of a sewing needle and moves relatively to the sewing needle and seam is made on the textile held with the holding frame according to predetermined sewing data. After a change of sewing speed and multiple sewing operations, the process of memorizing the sewing speed of each sewing operation and the amount of position gap detected for every stitch of the sewing data in the sewing speed in a data memory 202, the process of specifying restricted rotation speed of a main shaft as a sewing speed which minimizes the amount of the position gap for every memorized stitch and the process of correcting the sewing speed for every stitch of the sewing data according to the specified restricted rotation speed of the main shaft are performed.
