In the traditional design, CNC machining is based on the drawings designed by CAD, so it is inevitable that there are two sets of the same part data in CAD and CAM, which is easy to lead to management confusion. In this way, 3D CAD technology can help designers reduce a lot of workloads, reduce working time, and improve working efficiency by 3-5 times. Similarly, when the size and shape of parts change, other related structures will also change. However, in the process of parametric and variable design of 3D CAD, parts can be changed according to the change of structure size to achieve the appropriate effect.
CAD DRAWING SOFTWARE
Traditional CAD drawing software and existing two-dimensional drawing software can’t realize the parametric design. (3) Reduce design time and improve efficiency When designing parts, designers can use 3D entities or even 3D entities with quite complex constraints to design, realize the simulation assembly and simulation operation in the design stage, so as to make the design closer to the actual process. (2) Facilitate the assembly of parts more convenient and intuitiveĬAD software makes 3D design can show the structural features of components vividly and intuitively. In addition, CAD and CIMS are also applied to organize production, which promotes the new development of the mechanical product design. The mechanical product is integrated with information technology. With the support of 3D CAD technology, modern mechanical production uses advanced design methods to improve the level of design and ensure the quality of products, involves optimization, virtual design of products, finite element stress analysis, motion simulation, etc.
(1) Improve product quality and technical content In general, the advantages of 3D CAD technology and software than 2D CAD for mechanical design are as follows: It’s also easier to show and explain the product in presentations to consumers and workers with a 3D model. While with the 3D CAD model, we can see the final product, most people can understand the design. The model contains various information about the points, lines, faces and entities of the product geometry.īecause the 2D CAD drawings are plane, designers have to understand how the final product look clearly, this may be difficult for people who do not with the technical background. The core of the 3D CAD system is the 3D model of the product, which represents the actual shape of the product on the computer.
In the 2D CAD system, products and engineering design drawings are generally regarded as a collection of geometric elements such as points, lines, circles, arcs, etc., rely on the geometric models. While 3D is defined as 3-dimensional drawings or models they described objects with height, width and depth.ĢD CAD drawing is related to rectangle, square, triangle, polygon, etc., and 3D drawing is including cylinder, cube, sphere, pyramid, prism and more.ĢD drawings are typically measured in square units like cm², while 3D measurement includes cubic unit cm³, and quart liters. 2D CAD is a two-dimensional Computer-Aided Design, 3D CAD is a three-dimensional Computer-Aided Design.ĢD is a display of length and height on a plane without depth.
