Method for Determining the Normal Times of Machine-Hand Suboperation in Sewing Seams with Two Radii of Curvature

This paper describes the methods for determining the normal times of machine-hand technological suboperations in sewing curved seams with two radii of curvature, based on systematic research and measurements during the performance of machine-hand suboperations in sewing. For that purpose measurements were performed in the laboratory of the Department of Clothing Technology at the Faculty of Textile Technology, University of Zagreb, using modern measurement equipment, as well as the recording technology of the process of sewing clothes in a real production process. After that, the video recordings were analyzed and the times of performing the sewing suboperations were extracted. Based on the measured data a mathematical model and a computer program to calculate relevant parameters in joining work pieces with two radii of curvature BIR were established.
