The mechanical design basis of Guangdong machining plant refers to the design of mechanical devices and mechanical systems - machines, products, structures, equipment and instruments. Most mechanical design requires the use of mathematics, materials science and engineering mechanics. We are interested in the whole design process. How did it start? Can engineers just sit at a white paper table and start designing? When he wrote down some ideas, what should he do next? What influences or controls the decisions that should be made? Finally, how does the design process end?
Sometimes, though not always, design begins when Guangdong Machinery Factory recognizes a need and decides to do something about it. It is often a highly creative job to recognize this need and describe it clearly in language. Because this need may be just a vague dissatisfaction, an uncomfortable feeling, or the feeling that something is incorrect. This need is often not obvious. For example, the need to improve the food packaging machinery may be due to excessive noise, changes in the weight of the package, small but perceptible changes in the quality of the package, etc. There is a clear distinction between describing a need and the problem to be solved later. The problems to be solved are more specific. If clean air is needed, the problem to be solved may be to reduce the dust emission from power plant chimneys, or to reduce the harmful gases emitted by cars.
Guangdong mechanical processing plant should formulate all the requirements of the design object in the problem determination stage. These design requirements include input quantity, output characteristics, space size occupied by design object and all constraints of these parameters. We can think of design objects as something in the black box. In this case, we must specifically determine the input and output of the black box, as well as their characteristics and constraints. These design requirements will define production cost, yield, life expectancy, operating range, operating temperature and reliability. There are also many implicit design requirements due to the specific environment of the designer or the nature of the problem itself. The manufacturing process and equipment available in a factory will limit the work of designers and thus become part of the implied design requirements. For example, a small factory may not have cold working machinery. Therefore, designers must choose other metal processing methods that can be carried out in this factory. The technical level of workers and the competition in the market are also part of the implied design requirements.
After Guangdong mechanical processing plant has determined the problems to be solved and formed a series of written and implied design requirements, the next stage of design work is to synthesize to obtain the optimal results. Because only through the analysis of the designed system can we determine whether its performance meets the design requirements. Therefore, without analysis and optimization, the synthesis cannot be carried out. The design work is a repeated process. In this process, we have to go through several stages. After evaluating the results, we can go back to the previous stage. Therefore, we can synthesize several parts of the system, analyze and optimize them, and then synthesize them to see how they sometimes affect other parts of the system. Analysis and optimization require us to establish or make abstract model of the system, so as to carry out mathematical analysis. We call these models mathematical models. We hope to find a good mathematical model to simulate the actual physical system when we build the mathematical model in Guangdong mechanical processing plant. Evaluation is an important stage in the whole design process. Evaluation is the final test of a successful design, usually including the laboratory test of the prototype. At this stage, we hope to find out whether the design can really meet all the requirements. Is it reliable? Can it win in the competition with similar products? Is it economical to manufacture and use this product? Is it easy to maintain and adjust? Can profit be made from its sale or use? It is the last and key stage of the design process to communicate with others about the design scheme. There is no doubt that many great designs, inventions or creations are not used by human beings because the creators are not good at or willing to introduce their achievements to others. To come up with a plan is a job of persuading others. When an engineer puts forward his new plan to the operation, management department or his supervisor, he hopes to explain or prove that his plan is better. Only when this work is successfully completed, can the time and energy spent on this project not be wasted.
There are basically only three ways for people to express their thoughts, namely, written materials, oral expression and drawing. Therefore, an excellent engineer should be proficient in these three expressions besides mastering technology. If a person with strong technical ability is poor in one of the above three expressions, he will encounter great difficulties. If the above three abilities are poor, no one will ever know how capable he is! A competent engineer should not be afraid of the possibility of failure in presenting his own plan. In fact, accidental failure is bound to happen, because every truly creative idea always seems to be accompanied by failure or criticism. We can learn a lot from a failure. Only those who are not afraid of failure can gain the most. In short, the decision not to submit the proposal is a real failure
