Evaluation of stitch length accuracy of embroidery machine by different speed and step

Abstract

The key factor for high quality embroidery is the precision with which the individual stitches are realized in the plane of frame XY. For this purpose, the dispersion in the size of each step on X and Y axes are measured, depending on the step length and the machine speed. The studies were carried out in the entire stroke of the two axes. To evaluate only the positioning error of each individual step the measurements without removing the embroidery fabric from the frame are made in order to eliminate deformations caused by fabric relaxations. The results obtained are particularly relevant for evaluating the ability to produce elements as small as possible.
