With the rapid development of technology and the accelerating of global economic integration, the competition environment in manufacturing industry has been changed radically. Product quality plays a key role to succeed, so how to improve quality receives Increasing attention by most scholars at home and abroad, also by many enterprises, process quality is the most important section of quality formation during manufacturing process. The control of process quality not only keeps the products manufactured steadily, but also optimizes the design and fabrication technology of the product by analyzing and controlling the quality state. Through the analysis of the controlling technology of the process quality, combining with the traits of electric machines quality control, this paper mainly researches on the process quality control and optimization in the steel wire, using process control chart or other methods to control the manufacture quality.The paper takes working procedure quality as the research object, which is the key control in quality forming process. Take systemic discusses on integrant part of working procedure quality, control method, the rationale, behavioral science etc. Investigation of working procedure quality improvement and working procedure quality control content is also included. Efficiency is carried on the whole system. Study the domestic and foreign quality control developing process and got a complete understand on the present situation research. On the basis of analysis of procedure quality control methods and procedure appraisal, revolves the above working procedure quality control content, a method using computer realize on-line control is proposed, which get advanced performance in electric machine procedure control.The system can use in conditions of single working procedure, multi-working procedures and the regional quality control, and can carry on fail-safe analysis and efficient analysis to working procedure quality itself. It adds important value on the steel wire manufacturing enterprises.
