Analysis of the relationship between the shape and function of the GeorgV 2 virtual axis machine tool of the 5-axis hybrid machine tool of the Manufacturing Engineering and Machine Tool Research Institute (IFW) 4 The relationship between the modeling of the virtual axis machine tool and the aesthetics and ergonomics The design of the virtual axis machine tool emphasizes the function In harmony with the styling, the styling is based on function and reflects the functional beauty. The virtual axis machine is functionally integrated with various processes such as machining, measurement, assembly and material handling; it is high speed, high flexibility, light weight and low cost integration in performance. Excessive emphasis on functionality and neglect of styling quality, or the pursuit of aesthetics without embodying functionality, can affect the functionality of the product. The virtual axis machine tool is a kind of numerical control machine tool that reflects the characteristics of the product in the era of knowledge economy. Its shape must produce scientific and rigorous abstract functional personality in human thought and psychology, that is, enhanced functional beauty.
3 The relationship between the shape and structure of the virtual axis machine tool The early appearance of the prototype has great similarity in structure, and most of them adopt the relatively standard Stewart platform structure. In the subsequent research, a variety of new structures (shown in 2) have emerged, each with its own characteristics and applicable fields.
In recent years, the design of machine tools has attracted more and more attention to aesthetics and ergonomics. This is the result of the development of modern design and the demand of market competition. The style and temperament of the CNC machine tool styling meet people's aesthetic requirements.
The total number of parts of the virtual axis machine tool is less than one quarter of that of the conventional machine tool, and the structure is simplified and the integrity is good. In order to obtain a holistic shape, two methods are generally used: one is to improve the clarity and uniformity of the shape and body "block" feeling () | 2L is to use a fully enclosed shape (), this method of reducing exposed parts From an ergonomic point of view, it improves visual stability and reduces the environmental impact of noise and processing waste.
Multivariate refers to the diversification of the style of virtual axis machine tools. 1 Use structure to express shape () to express the beauty of the shape with the scientific and advanced nature of various new structures; 2 Maintain the style of ordinary CNC machine tools (). This style conforms to the machine modeling style that people have seen, and is the leading mode of virtual axis machine tool design; 3 modeling is original (). Based on the structural characteristics, the design of the design breaks through the traditional sense of CNC machine tool style, which is refreshing. This will be the future development trend of virtual axis machine tool design.
German Machine Tool Institute (FW) 6-axis milling machine: the development of Neos material science in Sweden, the emergence of new special technology, providing an effective means for the beautification of mechanical and electrical products. The color of the finish, the natural color inherent in various materials, the reflection of the surface texture light formed by the different processing methods and the surface decoration process, can produce more attractive and multi-layered chromatic effect | 21. Ergonomics The principle and method are applied to the design of the virtual axis machine tool, which greatly improves the production efficiency.
5 virtual axis machine tool design method should determine the relevant size data |3) according to the technical parameters specified in the design task book, thus forming the basic shape of the machine tool shape. Then determine the style of the machine. Nowadays, the machine tool adopts a fully enclosed shape, and the protective cover is basically bent from a steel plate. Considering the processing technology and cost of the metal material, a straight square box style or a trapezoidal style can be adopted, and different transitions are adopted between the shapes. (such as small rounded corners) way to enrich the line type of the machine. In order to reflect the humanized design trend, the surface of the machine can also be curved. For the virtual axis machine tool, in order to express the characteristics of the structure, it is not necessary to cover the inside with a large piece of steel plate. The plexiglass can be used as the main body of the protective cover, so that the sliding door and the observation window are combined into one, which is beneficial to The surface design of the machining process can achieve a clean and bright effect. The color design of the CNC machine tool presents a variety of features. A set of color, two sets of colors, and three sets of color matching methods can meet people's aesthetic needs in a wide range, and conform to the popular tendency of various combinations of social colors.
The characteristics and continuity of the image, the color design of the machine tool should try to maintain the original color tone.
3) Ergonomic design The working environment of the virtual axis machine tool is neat, and the direct operation of the machine tool is mainly concentrated on the control panel. Therefore, the shape and color of the machine tool should be coordinated with the environment. The operator feels comfortable and improves efficiency when working.
The size, shape and position of the virtual axis machine control panel (integral, hanging, down-draw, free-standing) should ensure that the operator can observe and work conveniently. The layout of the control panel is in line with the human visual response and is convenient for the operator to operate.
The size, position and height of the sliding door, observation window and table on the virtual axis machine should conform to the size of the relevant parts of the human body, so that the operator can easily observe and load and unload the workpiece.
Decoration (corporate logo, trademark, factory name, etc.) design is a means to further improve the artistic effect of the product. Pay special attention to the reasonable use of the logo that represents the corporate image to meet the long-lasting requirements of the company's image and product quality.
6 CNC boring and milling virtual axis machine tool XNZ63 modeling design example The author is now working with the Yunnan Provincial Provincial School Cooperation Project “Development, Design and Development of Virtual Axis Machine Tool Commercial Model†in cooperation with Kunming Machine Tool Factory of Tsinghua University. Milling virtual axis machine tool XNZ63 shape design.
The structure of the XNZ63 is as shown. The three vertical frames are each equipped with two branches, and the six-axis linkage allows the end-effectors of each branch to reach any position in the workspace.
According to the structural characteristics of the machine tool, combined with the existing conditions of the factory, and the modeling design style of today's CNC machine tools, the modeling style of the machine tool is determined: the fully enclosed, straight and straight line style.
The machine is simple in shape. This method of "seeing the circle in the square and seeing the square in the circle" enriches the linear shape and makes the shape natural, vivid and beautiful.
Now I have sampled 50 true color pictures from domestic and foreign CNC machine tools (CNC, grinding, milling machine, machining center) for quantitative analysis of the number of main body color of CNC machine tools, 14 for designers to learn from.
The color of the main body is 14%. The choice of a set of colors is easy and generous, and it is easy to coordinate with the environment. But the hue is too single.
The color of the main body is 60% of the two sets of colors. The configuration of the two sets of colors can distinguish the primary and secondary, highlighting the main color, and the color changes are rich.
The main color is 26% of the three sets of colors. It is difficult to use three sets of colors, which is easy to cause color confusion, and the overall feeling is not strong.
In color design, we must pay attention to the specialization and standardization of corporate color style.
The color style of the enterprise product represents a kind of corporate culture, in order to ensure that the enterprise's shape sliding door is in front of the machine tool is the design focus. The sliding door is divided into two left and right sides, equipped with a pulley sliding, and its moving area ensures sufficient space when loading and unloading the workpiece. In order to obtain a better viewing angle and viewing range, in addition to providing two viewing windows on the sliding door, observation windows are also provided on the remaining two sides. The observation window adopts a plexiglass shape with a rectangular shape and a small rounded transition, and a sealing strip is embedded around the window.
The handle is an important part of the machine tool. In this design, the handle adopts a large arc design, which is consistent with the overall line style. (Continued on page 25) Effect Conclusion This paper uses fuzzy logic based method to control the obstacle avoidance of two-wheel differential mobile robot. First, the risk of collision is introduced, and the risk of space collision is used as the input variable of the fuzzy controller. This description of the collision risk relationship between the mobile robot and the obstacle is more accurate and comprehensive. Second, the mobile robot The 180* range of the front sensor perception is different from the traditional division. This division transforms a four-dimensional fuzzy control into two two-dimensional fuzzy control, and corrects the left front and right front rules with the left and right rules. And supplements, the number of rules formed is small. Simulation results show that the method is effective.

A fiber laser is a laser where the active medium being used is an optical fiber that has been doped in rare elements; typically, erbium, ytterbium, neodymium, thulium, praseodymium, holmium or dysprosium. While you don`t need to worry too much about which rare-earth elements have been used, the main thing to note is that it is fiber that is being used at the centre of this Laser Machine. This is different to the two other main types of laser, which are gas lasers (typically uses helium-neon or carbon dioxide) and crystal lasers. Fiber lasers are the newest type of laser to hit the market, with many arguing that it is the more beneficial of the three types.
