From the design stage to improve product quality and quality of the innate

Global economic development and intense market competition, product quality to win business users become a critical factor. How to effectively improve product quality, especially from the design stage to improve product quality innate quality, has become a topic of concern for many experts and scholars. In this context,  Diamond blade  product quality, improve product performance and robustness of the new design method - robust design came into being. Modern design is based on sound engineering model, and computing technology, optimization techniques combining design methods. This paper, the optimal design methods and robust design ideas  synthetic diamond  integrated, is proposed based on stochastic simulation test robust optimization design method. By analyzing the design of products to achieve robust way to establish a robust design objective function; passing  abrasive grinding , the variation of the control design parameters affect the function of the design, to ensure the robustness of the design solution; analysis of robust stochastic optimization design quality characteristics sex, the use of probability theory and mathematical statistics theory, stochastic simulation method of product quality statistical calculation and processing characteristics.

Hardened finishing technology has made ​​great progress, and the emergence of some new processing methods

In order to improve the carrying capacity of the gear at home and abroad since the 1970s has been widely adopted hardened technologies. Over the years, hardened finishing technology has made ​​great progress, and the emergence of some new processing methods. We combine shaving honing method and the method has the advantage, developed a new structure of the coating with CBN honing wheel, and a plating method to improve the diffusion honing wheel CBN materials and the bonding strength between the substrate. The structural design of the honing wheel structure honing wheel, there are two, namely the overall style and assembled (see Figure 1).  abrasive grinding  in the overall through-slot basis, the development of CBN honing wheel  abrasive wheels  by the gear-shaped cutter body 1, the gear-shaped plate 3, the gear plate 2 is composed of honing shape, positioned by the positioning pin 4, using six bolts 5 fixed. 1,3 on the tooth surface with a certain  Diamond blade , width 4mm, serves as a guide only. The honing width of 10 ~ 11mm in round honing surface of the tooth plate 3 is plated with CBN abrasive, the use for honing. Meanwhile, in order to facilitate and reduce the chip honing pressure, the honing on the board with two flute, thereby forming three honing surface and the respective side edges. In honing, in addition to the tooth surface of the honing tool effects, both sides of the blade will have a shaving function, honing plate 2 are interchangeable.

On honing processing principle is analyzed

For the above problem, we conducted a magnetic field on the electroplated CBN honing tool Numerical Analysis of the role. Its main contents are: (1) First, honing processing  is analyzed, including the engagement of honing processing conditions,  abrasive grinding , no backlash regular engagement, honing knife cutting research. (2) in the study honing process on the basis of the principle of honing tool has been designed, including  abrasive wheels  calculation, calibration honing wheel and be added to the center distance between the gears, shaft angle, radial clearance and gear to be machined shaped involute length, and finally the use of three-dimensional design software Pro / E for honing knives were modeled.

Honing is a new and widely used gear finishing techniques

Gear is an important part of automotive transmission, along with the rapid development of modern automobile industry to improve the carrying capacity of gears and precision is particularly important. Honing is a new gear finishing technology and is widely used in automobile manufacturing. Honing abrasive wheels tool used by many forms, its  synthetic diamond  process is also of concern in the academic community. This paper intends to honing machining of a new tool - Plating CNB honing knives research. Currently, the electroplated CBN honing knives mainly exists in the manufacturing process: participation in the tooth surface honing knife cutting superhard materials CBN grains and metal coating bond strength is not enough, the uneven distribution of electroplating CBN grains and other issues.

Some Hardened reducer with the same rated power compared to a soft tooth surface reducer

Gears and gearing is an important foundation for machinery products in parts. With the development of machines, especially the rapid development of automobile industry, the demand for gear growing exponentially, and the accuracy of the gear increasingly demanding. From an international point of view, gear manufacturing technology is moving in the manufacture of high load capacity, high tooth surface hardness,  abrasive wheels  gear direction. Hardened gear greatly facilitated the adoption of the machine weight, miniaturization and quality performance improvement, making the machine work faster a grade. For example, in the case of other conditions are the same, instead of using hardened carburizing quenching soft tooth surface gear carrying  synthetic diamond powder  be increased by 2 to 3 times the number of Hardened reducer with the same rated power soft tooth surface reducer compared life can be increased more than 3 times, the weight and volume can be decreased by 40% to 60%. Visible, hardened, high-performance gear. For now, the domestic gear  Abrasive grinding wheel technology can not meet the high-volume, hardened, precision gear production requirements, in order to further improve the technical level of the gear finishing in gear manufacturing gear cutter and its proposed new design theory methods particularly important. Based on the above ideas and tools currently exist electroplated CBN honing wheel low accuracy and short life issue, electroplated CBN honing wheel hard honing radial technology.

Combined with an internal combustion engine coupled parts precision machining project eyelet hole processing technology

Heng plating with low life, the size should not be guaranteed, processing technology immaturity, etc., have not been satisfactorily resolved. These problems seriously restricting domestic small hole finishing technology and development. Therefore, this article combines an internal combustion engine coupled parts, precision hole  cutting tools , hole  grinding wheel  technology used in electroplating honing with the preparation and application of technology has been studied, the paper in the following  cubic boron nitride  analysis. Analysis summarizes the domestic small diameter deep hole processing technology, introduced the current hole processing technology and the latest research in this area in the domestic situation.

Holes and even cutting research field

Small diameter hole finishing techniques, because of its wide range of applications, the importance and difficulty of processing high, has been a hole processing and even cutting research field content. American hole processing technology, also known as  abrasive wheels , the use of diamond or cubic boron nitride abrasive grains produced by the electroplating honing tools, honing technology compared with the conventional,  grinding wheel  accuracy, shorter  Diamond blade time, fewer skills and lower processing costs, and therefore the future precision hole processing technology is an important development direction. However, research in this country is still very limited, there are some problems.
