To improve the level of large-scale CNC Machining technology, we can start from the following aspects: 1. Pay attention to the upgrading of mechanical CNC software and hardware systems: Mechanical CNC software and hardware systems are the core of large-scale CNC machining technology, and their upgrading can effectively improve machining accuracy and efficiency. Therefore, attention should be paid to the development trends of technology at home and abroad, and software and hardware systems should be upgraded and replaced in a timely way to improve the stability, reliability and efficiency of the system. Innovative mechanical processing equipment: Innovation is the driving force for improving technology level. Enterprises should actively introduce new technologies and processes, carry out technological transformation and equipment upgrades based on their own actual situation, develop specialized CNC equipment with independent intellectual property rights, and improve the overall technical level of large-scale CNC machining. 3. Fully realize automatic programming for mechanical processing: Automatic programming technology can improve programming efficiency and accuracy, and reduce errors caused by human factors. Accordo, automatica programming technology should be actively promoted to achieve direct conversion from CAD/CAM to CNC and improve the automation level of the machining process. 4. Reasonable selection of machine tools: Tools are an important factor affecting machining accuracy and efficiency. Enterprises should select tool materials, geometric shapes, and cutting parameters reasonably based on processing needs, establish scientific tool management systems, and improve tool efficiency and lifespan. 5. Improvens litteratur technica personālae procedentis: Processus personnel sunt implementatores maximae technologiae machinae CNC, et litteratur tecnica eorum directo ad qualitatem machinae influent. Enterprises should strengthen the training and education of process personnel, improve their technical level, practical ability, and innovation awareness, so that they can better complete process scheme design, processing parameter selection, and process monitoring. 6. Strengthen technical exchange s and cooperation: Strengthen technical exchanges and cooperation with domestic and foreign peers, actively participate in industry technical exchange activities, understand the latest technological trends and developments, learn from advanced technological achievements and experiences, and promote the improvement of one's own technical level. 7. Attention a quality inspection and control: Quality is the lifeline of enterprises. Enterprises should establish a sound quality inspection and control system, strengthen process monitoring and finished product inspection, timely discover and solve quality problems, and ensure the stability and reliability of product quality.
