Generally, 80% of the production cost is decided in the design stage, which is an important link to control the product cost.At present, in the enterprise product research and development process, the industrial design always plays the overall situation important role.At the beginning of industrial design, decisions are made on product design positioning, cost control, production and manufacturing, quality testing, publicity and display, marketing and recycling treatment of the whole cycle for comprehensive consideration, with far-reaching influence. In the process of industrial design, CNC prototype fabrication is an important link. From pure manual model making to semi-mechanized model making to modern CAM, the progress of hand model making is a miniature of the progress of modern manufacturing technology. Practice has proved that the production of prototype not only plays a very important role in product design decisions. Is product information confidentiality and marketing tools, not to be underestimated. Below from the different stages of the industrial design process to see the importance of hand-made model.
1. Design optimization
Modern industrial design covers a wide range of contents, from paper clips and ballpoint pens to airplanes and ships, all of which contain the shadow of modern industrial design.But so many products are designed differently.Mechanical parts that focus on geometric shapes can be well designed directly by computer graphics, In addition, some motion simulation experiments can be carried out by using the dynamic laws of computer 3d software. For some products with curved surface, such as household appliances products, First, you can design directly by computer. Secondly, 3d modeling data can also be obtained through 3d mapping by reverse engineering technology ,After smoothing correction by the difference algorithm of computer, the corrected 3d model data can be used for prototype fabrication. This method has more obvious advantages when designing artworks that focus on the changes of surface modeling. Since the exterior modeling of artworks focuses on people's direct aesthetic feelings, there are often no rules to follow, and it is difficult to find regular geometric elements in them. If the computer three-dimensional drawing is directly carried out, it will only get half the result with twice the effort. Even if the model is established, its subsequent modification is very poor. If the opposite is done, first of all by the modeling designer directly with sludge and other materials to shape the shape, and then through the three-dimensional scanning equipment to parameterize the model, get the original model computer data and then further through the hand rapid model equipment to make processing, can greatly improve the design efficiency.
2.Design discussion
In the process of product design, discussion is very important. Visualization is an important part of product design expression and the cornerstone of design discussion.Rapid and effective product modeling can achieve higher design efficiency in the same time.In the stage of design creativity, 2D representation based on drawings is often used.However, in the middle and late stage, the design performance will be more specific, and a more specific and intuitive hand model should be adopted as the object of discussion.Compared with the 2D performance of the plane, the prototype has irreplaceable advantages. The prototype can make the details of the product clearer and the visual perception of the product more intuitive.Everyone in the design team can see these designs, which has obvious advantages in coordinating the work of the whole team.the design efficiency can be greatly improved if the model is made and processed by the hand plate rapid model equipmentafter obtaining the computer data of the original model.
3.Functional testing
The prototype fabrication can be made for functional tests.Can simulate product morphology, including functional morphology, surface morphology, etc. Using materials with a certain strength (such as ABS, PC, etc.), a functional prototype with internal structure can be made. In order to test whether the structure of the product is reasonable, wall thickness is in line with the requirements, smooth moving parts, etc. The prototype can also be used for aerodynamic test. For example, in the design of automobiles, high-speed trains or spacecraft, which need high-speed moving objects, A 1:1 model can be made and put into a wind tunnel for intuitive aerodynamics research.
4.Reduce costs
A design defect verified by a 1000-yuan prototype fabrication,If put into production, put into the market, may cause a huge loss of 10 million, In many cases, the problem is fatal. The steady progress of the design process is very necessary, so it is very important to timely find the defects in the product design process at the early stage of product design and timely correct them, so as to avoid problems in subsequent production. Among them, prototype fabrication is an important link that we can use. The shape, size, structure or color test of the product can be obtained at a small cost by prototype fabrication and can also predict product volume, quality and other important information, This can effectively control the cost of packaging, transportation and raw materials used in manufacturing, And then estimate the sales price and profit of the product. If the cost exceeds the original design, it can be adjusted in time until the target range of cost is reached. The production of prototype is an effective means of enterprise cost control.
5. Product confidentiality
Product design is an important part of the company's core competitiveness, The products need to be kept strictly confidential at the design stage. The division of labor in modern manufacturing industry is becoming more and more detailed. The advantage of design outsourcing is that it can save the cost of establishing an independent design institution within the enterprise and reduce the risk of product research and development, But this also brings the difficulty of product confidentiality, Even though the company has its own research and development organization, If the model stage still needs to be completed by an external design agency, there is still the possibility of leakage of design secrets. So the large manufacturing enterprises generally have their own independent research and development institutions, with their own prototype fabrication equipment, The research and development process of new products should be completed independently within the enterprise design team to reduce the contact with external service agencies, so as to ensure that the design data is not leaked and protect the design secrets of the enterprise.
6.Market research
In the trade fair, it is not more attractive to show flat boards or 3d animation demonstration to potential customers. The simulation model can directly show the shape, color, size, structure, function and other information of the product.The production of prototype is a convenient and quick initial performance of the product. Different schemes in the initial stage can be made into models, and market surveys can be conducted through exhibitions or actual verification by customers, We can also use the rapid prototyping technology to reproduce the model in small batches, and send the product model to different regions for investigation, so as to obtain more market differentiated survey data. The prototyping technology can predict the actual psychological effect and use effect of product consumers before mass production.
In general, with the progress of modern processing technology, the production technology ofprototype is becoming more and more perfect.At present, Duochuang prototype have four mainstream processing methods for prototype fabrication: CNC machining, SLA, SLS and vacuum casting.
