FIGURE 8 Product quality on machinery manufacturing sales impact Virtual automation is an important part of mechanical engineering. This project aims to reduce the complex processes in machine manufacturing, save unnecessary investment and effectively reduce the cost of machine manufacturing through new information technology such as artificial intelligence, computer graphics and multimedia. For example, virtual automation of machine manufacturing can perform various drafting tasks in a short period of time. Paperless virtual automation also saves a lot of paper resources. During the design, processing and manufacturing of the machine, the production of the machine must be effectively controlled to ensure that the design parameters meet the specified requirements.
