Strengthening the quality management of machining can effectively improve product quality and increase the market competitiveness of enterprises. According to the market demand, enterprises should adopt advanced and scientific management methods to strengthen the management and control of processing quality from all aspects. Aiming at the problems existing in machining quality management, the following improvement strategies are put forward. 1. Pay attention to the training and assessment of personnel, and the professional quality of relevant personnel is the key factor in the quality management of machining. Therefore, we should improve the quality awareness of machining operators and managers, realize the importance of product quality to enterprises, and regularly conduct professional training and learning for machining quality operators and managers to continuously improve the professional level of relevant personnel [3]. In enterprises, it is necessary to implement the quality responsibility system, clarify the responsibility of each employee, establish a scientific and effective quality management performance evaluation system, stimulate the enthusiasm of employees, and enhance the sense of responsibility of all employees. In addition, a technical team can be set up within the enterprise to concentrate on learning, which provides a new way for processing quality management and ultimately effectively improves processing quality management. Technicians should also adjust the relevant equipment according to the actual situation of the enterprise, rationally configure the equipment on the assembly line and realize the perfect combination of equipment. Control all links in the production process. Professional technicians are responsible for key production equipment, and make handover records and maintenance records. You can also organize a technical skill competition within the enterprise, and it is estimated that employees will study the equipment attentively and understand its working principle. 2. Improve and strengthen the monitoring and management during processing. In the process of processing, many production links are involved, such as turning, planing and pliers. Therefore, all processing links should be tested, and different testing methods should be set according to different production links to test key links. Qualitative detection and quantitative detection can also be carried out to ensure the controllability in processing [4]. For example, the cutting parameters of the product, feed mode, etc. Can be quantitatively detected to control its quality. In addition, we should attach importance to the construction of quality supervision department, integrate this department, clarify the responsibilities in production, and ensure the index detection and collaborative management in the processing process.
