The English abbreviation for Total Quality Management is TQM. The first to propose total quality management is Feigenbaum. He defines the total quality management: in order to be able to meet the requirements of customers at the most economical level. Conducting market research, design, manufacturing and after-sales services, and integrating the development quality of various departments within the enterprise, maintaining quality and improving quality activities as an effective system. The comprehensiveness of the overall quality management process determines that the content of total quality management should include the quality of the four processes of design process, manufacturing process, auxiliary process and use process. I. Content of quality management in design process Quality management of product design process is the primary link of total quality management. The design process referred to here includes the process of market research, product design, process preparation, trial production and identification (ie, all technical preparation processes before the product is officially put into production). The main work contents are as follows: 1. Through market research and research, according to user requirements, scientific and technological information and business objectives of the company, develop product quality objectives. The design goal of product quality should be derived from the needs of the market (including potential needs) and should be consistent with the requirements of users; it should have certain advancement. In the possible conditions, try to adopt international advanced standards. 2. Organize three-in-one review and verification of sales, use, research, design, process, system and quality control departments to determine the appropriate design. Different design schemes reflect different quality levels or design levels of the same product. Products of different quality levels will inevitably lead to differences in cost and price. The price of any product is usually limited. When the price exceeds a certain limit, the user will decrease. In order to improve the product quality level (design level), the rising cost is almost unlimited. Therefore, choosing a suitable design, from an economic point of view, there is a problem of the best quality of the product. 3. Guarantee the quality of technical documents. The technical documents mentioned here include design drawings, product formulas, process specifications and technical materials. They are the result of the design process, the basis for the production process activities of the manufacturing process, and the basis for quality management. This is to require the technical documentation itself to guarantee quality. The quality requirements of technical documents are: correct, complete, unified and clear. In order to ensure the quality of technical documents, the registration, custody, reproduction, issuance, recovery, modification and cancellation of technical documents shall be handled in accordance with the prescribed procedures and systems; the right to modify technical documents shall be centralized and strict modifications shall be established. Approval and signing system; the scientific classification and custody system of technology shall be established; the technical documents for delivery shall be borrowed and replaced with old ones. 4. Do a good job of standardization review. The standardization, generalization and serialization of product design not only help to reduce the types of parts, expand production batches, improve the quality of the manufacturing process, ensure product quality, but also facilitate the design workload and greatly simplify the preparation of production technology. Therefore, a good review of standardization should also be a part of the quality management of the design process. 5. Supervise and abide by the working procedures of the design trial system. To do a good job in the trial design of new product design, it should be carried out in accordance with the scientific design trial procedure. Generally, the working procedures are: research, testing, product design, sample trial testing and related process preparation, sample identification, stereotypes, small batch trial production and related process preparation, small batch identification, and fixed process. The enterprise shall proceed to the next stage while ensuring the completion and confirmation of the previous work. Any violation of this kind of work procedure, what is the side of the stage design, trial production, production is very harmful. Second, the quality management of the manufacturing process The manufacturing process here refers to the process of direct processing of the product. It is the basis for the formation of product quality and the basic link of enterprise quality management. Its basic task is to ensure the quality of the product's manufacturing and to establish a production system that can stably produce quality products and quality products. The main work contents are as follows: 1. Organize quality inspection work. It is required to strictly control the quality of each process, ensure production according to quality standards, and prevent non-conforming products from being transferred to the next process and production. It generally includes raw material inspection, inter-process inspection and product inspection. 2. Organize and promote civilized production. Organizing and promoting civilized production is an important condition for scientific organization to modernize production and strengthen the quality management of the manufacturing process. It requires: the objective law of the production process should be reasonably organized to improve the rhythm of production and achieve balanced production; there should be strict process discipline to develop the habit of consciously obeying; the products are neatly arranged, safe for storage and transportation; the equipment is neat and tidy; The tools are stored in an orderly manner; the work place is reasonably arranged, the air is fresh, the lighting is good, the surrounding colors are bright and harmonious, and the noise is moderate. 3. Organize quality analysis and master quality dynamics. The analysis should include analysis of the waste (or non-conforming product) and analysis of the finished product. The analysis of waste products is to find out the causes and responsibilities, to discover and master the regularity of waste generation, so as to take measures to prevent and eliminate them. The analysis of finished products is to fully grasp the dynamics of products reaching quality standards in order to improve and improve product quality. Quality analysis can generally be started from certain quality indicators, and there are two types of indicators: one is product quality indicators, such as product grade rate, product life, etc. The other is work quality indicators, such as scrap rate. , non-conforming product rate, etc. 4. Quality control of organizational processes and establishment of management points. Process quality control is an important means of ensuring product quality stability during the manufacturing process. It requires that non-conforming products be discovered and forecasted before they occur, and can be processed and controlled in a timely manner to effectively reduce and prevent the production of non-conforming products. Organizational process quality control should establish management points. The management point refers to the key processes or key parts that need to be specially strengthened and controlled under certain conditions within a certain period of time, based on a comprehensive analysis of the various processes in the production process, and are clearly targeted for quality management. It should use all necessary means and methods to strengthen management. The purpose of establishing a management point is to make the quality control work of the manufacturing process clear and focused, and to make the production in a certain state of operation standard management, to ensure the stability of the process quality.
