This paper presents the needle penetration materials used in the manufacture of shoe uppers pieces, namely the implementation of experimental studies piercing process details shoe uppers and processing of the results using the software complex LabVIEW. In carrying out experimental research efforts penetration of parts for the system "needledetaildetail", defined by the following parameters: the applied moment; thick material parts. Researching of penetration was conducted on an experimental setup that allows to model processes that occur during stitching piece. Processing of experimental data allowed obtaining the regression equation determining needle penetration efforts in split leather and vinyl artificial leather. For natural value equation supplied to coded X factor in the equation and receiving function depending needle penetration force as part of the applied torque and thickness of parts of the shoe uppers. The resulting differences analytical calculations and research results due to the inevitable errors of experiment and mathematical model of some inconsistency, resulting in the analytical study adopted provisions for simplification.
