In order to meet the market demand for high-quality and high-precision glass products, especially in mold manufacturing and surface treatment, it is particularly important to develop an efficient, accurate and cost-controlled glass mold surface generation method. With the rapid development of computer technology, numerical control technology and laser processing technology, new glass processing technologies have gradually been proposed, and these technologies have shown good application prospects in improving the efficiency and quality of glass mold surface generation. For example, the use of CNC machine tools for precision cutting and grinding of glass can effectively realize the processing of glass mold surfaces with complex shapes. At the same time, laser processing technology is increasingly used in micro-machining of glass surfaces due to its high energy density and excellent focusing characteristics. However, the traditional method for generating glass mold surfaces has the problems of low glass mold surface generation accuracy and poor optical properties of mold surface generated glass.

This process helps to understand the arrangement mode of the material at the microscopic level and reveal the uniformity and orderliness of its internal structure. The good degree of short-range arrangement is directly related to the physical properties of the glass, such as strength and toughness. The microscopic local structure unit analysis is performed based on the short-range arrangement data of the glass microstructure to obtain the glass microscopic local structure unit data. This analysis can identify and characterize the local structural characteristics inside the glass, including atomic clusters and local defects. By calculating the local atomic loss of the glass microscopic local structure unit data, the glass microscopic local atomic loss data is obtained. The existence of local atomic loss leads to a decrease in material performance, such as reduced strength and transparency. Therefore, identifying and quantifying these losses is crucial to optimizing the manufacturing process of glass. Understanding the distribution of missing atoms will help to make necessary adjustments in the mold design stage to reduce the impact of defects on the performance of the final product.

Transmittance is one of the key indicators to measure the optical properties of glass, which directly affects the visibility and optical effect of glass in practical applications. The reflectivity is calculated based on the microscopic local atomic loss data and transmittance data of the glass to obtain the reflectivity data of the glass microstructure. Reflectivity is another important optical property that affects the transmission and reflection behavior of light. By calculating the reflectivity, the optical properties of the glass are comprehensively evaluated to provide comprehensive data support for mold design. The optical microscopic properties are evaluated based on the transmittance data and reflectance data of the glass microstructure to obtain the optical microscopic properties data of the glass. The key to this step is to comprehensively consider the transmittance and reflectivity to comprehensively evaluate the optical properties of the material.

This analysis process can reveal the change of optical properties of the material under different temperature conditions and understand the stability and adaptability of the glass during the heat treatment process. This is very important for designing glass molds for high temperature processes, ensuring that the mold can effectively resist the performance degradation caused by temperature fluctuations in practical applications, thereby improving the reliability and consistency of the product. The evaluation process can identify the thermal damage suffered by the glass under high temperature or rapid temperature change conditions. This evaluation discovers potential quality problems in advance, allowing designers to take preventive measures in the mold design stage to reduce the risk of mold breakage or failure during the production process, thereby reducing production costs and improving production efficiency. Identify uniformity problems of the material at the microscopic level, such as the inhomogeneity of atomic arrangement or local defects. These defects can lead to a reduction in optical properties, such as instability of transmittance and reflectivity. By identifying these problems early, optimization is performed in material selection and mold design to ensure consistency and reliability in optical properties of the final product. This calculation can provide detailed information about microscopic defects generated by the material during the thermal phase change process, such as cracks, bubbles or other structural defects. This information is crucial for optimizing the glass production process and material formulation, and can help designers make necessary adjustments during the mold design stage, thereby improving the overall performance and quality of the glass.

The spatial distribution statistics of microcracks provide an important basis for evaluating the uniformity and potential weaknesses of materials, which helps engineers to carry out effective quality control during the design and manufacturing process. The calculation of the depth of optical thermal damage quantifies the impact of thermal effects on the internal structure of the material, and then evaluates its safety and stability in long-term use. By analyzing the degree of influence of optical thermal damage, we can more comprehensively understand how these damages affect the overall performance of the material, and help develop glass products that are more resistant to high temperatures and thermal stress. In addition, combining the spatial distribution data of microcracks with the degree of influence of optical thermal damage to calculate the microscopic defects of thermal phase change can reveal the microscopic defect characteristics of glass materials under different heat treatment conditions, thereby providing a scientific basis for optimizing the heat treatment process of glass and improving its application performance in high temperature environments. The effective implementation of this series of steps not only helps to improve the quality and performance of glass materials, but also lays a solid foundation for future research and development.

This process provides a reliable basis for all subsequent processing and molding processes, thereby reducing material waste and production delays caused by design errors and improving the overall efficiency of production. In addition, the accuracy of the geometric shape also directly affects the subsequent product assembly and use performance, ensuring that the product can achieve the expected function during use. The measurement of geometric dimensions is a key step to ensure that glass products meet design specifications. Through accurate dimension measurement, the existing dimensional deviations can be discovered and corrected in time to avoid subsequent processing and installation problems caused by inappropriate dimensions. The mold surface shape is constructed through glass geometric shape data and geometric dimension data, effectively improving the design accuracy of the mold. This process not only improves the matching degree between the mold and the glass, but also significantly improves the surface quality and appearance of the finished product. High-quality mold design can ensure the stability of the glass during the molding process, reduce the generation of defects, and improve the market competitiveness of the finished product. The initial glass mold surface is constructed in combination with the microscopic defect data of the glass thermal phase change, so that the mold design can fully consider the performance of the material under high temperature conditions.

This process enables the design team to identify the key factors that lead to mold failure at an early stage, thereby providing a scientific basis for subsequent optimization and ensuring the reliability and stability of the mold in actual production. By performing stress concentration point analysis on the mold surface defect impact data, the stress distribution characteristics of the mold under load are deeply explored. This analysis not only helps to understand the stress concentration of the mold under high temperature and high pressure conditions, but also reveals the weak links in the mold design, thereby providing guidance for strengthening the design and avoiding the risk of accidental damage or failure of the mold during use.
