(1) Product design is the starting point of the entire processing process. Designers use computer-aided design (CAD) software to create three-dimensional models based on the product's usage requirements, functional performance and design. In CAD software, designers can accurately define the shape, size, features and assembly relationships of parts.
(2) Commonly used CAD software includes AutoCAD, SolidWorks, Pro/Engineer, etc. These software provide rich functions and support parametric design, making it convenient for designers to modify and improve parts. During the design process, the feasibility of the processing technology must also be considered to avoid designing structures that are difficult to process or too costly.
