In this article we learn the topic Mechanical design and drafting this information is important for mechanical engineers and other design related works so lets start,

 Mechanical design and drafting

 Design means by which mechanical engineers design products and create instructions useful for manufacturing product.

• A Technical drawing or drafting is handwritten or computer model schematic show all dimensions needed to create product or part.

• Mechanical Drafting has historically two dimensional process, but now (CAD) computer aided design now allow to create three dimensional.

• The basic instructions to creating part must be fed to necessary machinery either manually or programmed instructions or (CAM) computer aided manufacturing or CAD/CAM program.

• Mechanical Design and Drafting refer to the process of creating technical drawings and specifications for mechanical systems and components using specialized software such as AutoCAD, SolidWorks, and CATIA.

  The mechanical design process involves creating a 3D model of the part or system using CAD software. This model can then be used to create 2D drawings, which include detailed information such as dimensions, tolerances, materials, and finishes. The drawings can be used for manufacturing, testing, and assembly.

  The drafting process involves creating detailed technical drawings of the mechanical parts and systems. The drafting process includes a set of conventions and standards used in engineering and design. These standards ensure that the drawings are clear, accurate, and easy to interpret.

  Mechanical designers and drafters use a range of tools and techniques, such as geometric dimensioning and tolerancing (GD&T), to ensure that their designs meet the necessary specifications and requirements. They work closely with engineers and other stakeholders to ensure that the design meets the project's goals and requirements.

   

Mechanical Design

Engineer have further option to manually manufacturer a part using technological drawings, but this is expand rarity, with use of  (CNC) computer numerical control manufacturing.

• Engineers first manually manufacturing part in areas of applied spray coatings, finishes and other processes that cannot be done by economically or practically done by machine.

Three dimensional models created using CAD software are also used in finite element analysis (FEA) and computational fluid dynamics (CFA).
