What is the main process of mechanical design?

Mechanical design is an important part of mechanical engineering, is the first step of mechanical production, is the most important factor in determining the performance of machinery. Mechanical design efforts to target: in a variety of limited conditions (such as materials, processing capacity, theoretical knowledge and calculation means, etc.) under the design of the best machinery, that is, to make the optimal design.

Optimization of the design needs to be considered in a comprehensive manner many requirements, generally: the best performance, the lowest manufacturing cost, minimum size and weight, the use of the most reliable, the lowest consumption and the least environmental pollution. These requirements are often contradictory, and their relative importance varies according to the type of machinery and use.

The main process

1, according to user orders, market needs and new scientific research results to develop the design task.

2, preliminary design. Including determining the working principle of machinery and the basic structure of the form, motion design, structural design and draw a preliminary general drawing and preliminary review.

3, technical design. Including modification of the design (according to the preliminary review), drawing all parts and new general drawing and the second review.

4. Working drawing design. Including the final modification (according to the second review), draw all the working drawings (such as parts drawings, parts assembly drawings and general assembly drawings, etc.), and develop all the technical documents (such as parts lists, wearing parts list, instructions for use, etc.).
