Engineers automatically + manual intervene workers read maps 3D conceptual design - 2D engineering drawings + axonometric drawings - also 2D drawings for 3D solids - machining manufacturing compares the above two processes and can be found in the designer's 2nd Most of the dimensional engineering of engineering drawings is done automatically by CAD software. It is very easy for workers to read drawings because of axonometrics. And, more importantly, when modifying part designs, 2D engineering drawings are automatically updated with 3D software technology; 2D CAD software and hand-drawn 2D drawings cannot be used to do this.
Establish a modern product design environment. Utilizing modern product design techniques, optimization design, reliability design, standardization techniques, and group technical principles to establish product specifications, including: the structure and combination based on the characteristics of parts, forming a standardized, modular, parametric design system. Concurrent engineering environment for manufacturing, assembly, and inspection. Make full use of mature technologies, create new principles and methods, and achieve innovative design.
3. The role and relationship of CAD/CAE/CAM/PDM CAE (Computer Aided Engineering) usually refers to the finite element analysis and the kinematics and dynamics analysis of the organization. Finite element analysis can complete mechanical analysis (linear, nonlinear, static, dynamic); field analysis (thermal field, electric field, magnetic field, etc.); frequency response and structural optimization. The mechanism analysis can complete the calculation of the displacement, velocity, acceleration and force of the components in the mechanism, the movement simulation of the mechanism and the optimization of the mechanism parameters.
CAM (Computer Aided Manufacture) can be used to automatically generate NC code for part machining and perform dynamic simulation, interference and collision check of the machining process. It is for CNC machine tools.
PDM (Product Data Management) product data management. Including engineering data management (EDM), document management, product information management (PIM), technical data management (TDM), and technical information management (Technical) Information Management-TIM), Image Management, etc., in a word, is all systems for managing product definition information.
CAD is the basis for CAE, CAM, and PDM. In CAE, whether it is a single part, or the finite element analysis of the whole machine and the motion analysis of the whole machine, CAD is needed for modeling and assembling. In CAM, CAD is needed for surface design, complex part modeling and mold design; and PDM Then it needs CAD to carry out the relationship after product assembly and the details of all parts (material, number of pieces, weight, etc.). Any changes made to parts and components in CAD will react in CAE, CAM, and PDM. Therefore, if CAD is not well developed, CAE, CAM, and PDM are difficult to do well.
4. The establishment of a CAD system As the leader of a company, it should seriously study the state's preferential policies for computer applications and try its best to obtain funds for relevant projects so as to understand the development of computer technology and the application of the same industry at home and abroad.
According to the company’s products, technologies, personnel, and funds, it established an application plan for five years or so; applying the method of system engineering, the company’s CAD system was gradually established with planning, organization, and goals. (To be continued)
