Optimization of assemble uppers systems using CAD/CAM

Abstract

The paper presents the optimization of assembly uppers using CAD/CAM systems based on bibliographic study and analysis of existing manufacturing tehnologies in the enterprise shoe ISC „Cristina Mold-Rom Simpex” SRL, Chisinau city. The purpose of this paper is to improve existing technologies uppers assembly in the company implementing new ways of designing manufacturing technologies footwear with uppers of leather. The practical value is to: develop automated design of technological process of assembling uppers of leather; developing unified database assembly faces technological operations; expanding the base of information about the process of assembly. The need for rapid introduction of high design constantly pressuring all companies producing shoes. Be the first to bring a new style shelves is often the difference between success and failure in business. The case study was conducted at the footwear company EFC "Cristina Mold-Rom Simpex" LLC, with conventional tehnologies and modern tehnologies. They have been made 10 models of shoes, is found the following: between clasical and modern tehnologies is a difference of 1 to 5.0 min; number of workers performing traditional sewing machines, ranging from 1 to 2 workers on the automatic sewng machine made to engage a worker. Active introduction CAD/CAM systems in light is an innovative tehnique that allwows improving the manufacturing uppers enchancing the quality uppers; decreasing the number of workers involved.
