Choosing five kinds of curved surface finishing methods is commonly used in CAXA and processing compared to the same curved surface parts, on the premise of making the parts same residual height and exploring their selection principle.

When energy crisis is somewhat relieved by the shale gas production, serious negative impacts are simultaneously created to the environment e.g. the regional underground water system will be seriously damaged. Currently, the shale gas production, which is blossoming in China at present, centralizes primarily in the South-west area, where the hydrological environment is quite complicated and pretty weak. In this paper, three threatens caused during the shale gas exploitation is summarized and the crisis source is also outlined. Furthermore, the probable solutions aiming at these problems are discussed, thereby the concept of ‘Water resources tolerance ability evaluation model in SouthWest China’ being proposed. This paper emphasizes that the further enhancement of environment monitoring, improvement of legislation in the related areas as well as domestic adjustment of production technologies are critical to balance the industrializing production and sustainable development.

The Multi-functional medical bed has been designed to the patient whose life cant been provided for oneself, critically ill patients, and the special needs of paralyzed patients. In the paper, through market research and according to the structure of existing medical bed, a manual medical bed has been designed; And the bed board, lift back and leg mechanism, defecation device and eat device of the medical bed have been discussed; the feasibility analysis of the motion mechanism has been carried and the basic design parameters of the product have been determined; on the basis, the main structure for medical bed has been carried on the design and calculation. The results showed that function of the medical bed is reliable, the structure is reasonable, and it is in line with the requirements of ergonomics. Especially, some of these institutions have been optimized and replace to use more convenient and quickly.

Mechanical rotary table [ has been widely used in many work applications, where rotating capacity and power of the table are necessary elements to ensure the operation safety. The paper provides a rotary table design operated by hand movements to lift and fall, rotate and turn over in the absence of electricity and other external powers. Therefore, table should have a simple structure and be easy to maintain, meanwhile working area should be wide enough for convenient operation. Simultaneously good safety performance is of great significant in this design, which requires a reasonable arrangement of each components position to minimize the number of dangerous sections. The rotary part applies commonly used clamping flange, which allows the table to clamp different types of components. Mechanical rotary table can be applied in many different occasions, making it a truly multi-functional workbench.

In view of well- designed showing platform is advantageous to promoting exhibition effect, the author analyzes the developing course of showing platform, and combining the mechanical design problem of existing showing platform which exists in using function, art function and material technique function and others, discusses the mechanical design requirement, the fundamental structure and working principle, the shape design and the color design of showing platform of rotation and vertical reciprocation. Among them the fundamental structure and working principle mainly elaborate the constituent parts of showing platform, the structure characteristics and working manner. Then the possibility is analyzed. On this foundation, the practical application of showing platform of rotation and vertical reciprocation is analyzed.

According to physiological and psychological characteristics of adults, this paper proposed sled design based on ergonomics. The paper respectively provided human research, analysis and design for two aspects directly related to ergonomics, handlebar and seat, in order to make product safer, more comfortable and effective to meet consumers demands.

In view of that manufacturing practice is indispensable practical links in the mechanical industrial design, the author analyzes the current situation of manufacturing practice in the mechanical industrial design and the existing problem in manufacturing practice system. And then The author puts forward a series of methods and concrete measures about manufacturing practice platform construction of mechanical industrial design , including constructing the new mode of manufacturing practice of mechanical industrial design major, constructing the stable base of manufacturing practice, improving the understanding to manufacturing practice and knowing the major role and strengthening the construction of instructors troops of manufacturing practice, Which will certainly have a profound theoretical and practical guiding significance. On this foundation, the study summary on manufacturing practice platform construction of mechanical industrial design is done.

RMB contains a large number of coins in circulation in the financial and other fields, this coin inventory and classification, is through manual means, this mode of operation and low work efficiency and give the operator a great trouble, the labor intensity greatly, and not accurate. In the paper, an automatic sorting and measuring machine has been designed and mainly used for sorting, counting, packaging to a variety of coin. The main function of automatic sorting and measuring machine are automatic sorting, counting and packaging. The machine mainly consists of mechanical systems and control systems. It is applied to the modern innovative design and it is the device meeting the need in places for many small denominations of currency. The machine has achieved automation, improved labor productivity, and also brought many conveniences to life. The machine is the inevitable trend of future development.

In this paper, bionic design of the sled motor body has been introduced on the basis of the main structural features of sled motor. The bionic design included the body design and color design. The theories of the law of formal beauty for the shape and color collocation have been rationally analyzed. And the conclusion has been achieved that there is one process from sensibility to rationality in the bionic model design and color design. It is also the design process, rule and pattern of the abstract form in bionic design.
