With the continuous innovation and breakthrough of numerical control technology, five axis machining is adopted by more and more industries, such as aerospace, electric power, shipbuilding, high-precision instruments, mold manufacturing and so on. However, the automatic programming software plays a key role in the five axis machining technology, because the process layout of the tool path, the interference inspection between the tool collet and the workpiece or the fixture, and the identification of the blank residue are all automatically considered by the software, and the programmers can not achieve it through calculation. They just optimize the cutting parameters according to…

With the development of science and technology and the diversification of social needs, the competition of products is becoming more and more fierce, and the renewal cycle is becoming shorter and shorter. Therefore, it is required not only to design new products as soon as possible according to the requirements of the market, but also to manufacture prototypes in the shortest possible time, so as to carry out performance testing and modification, and finally form finalized products. In the traditional manufacturing system, it needs a lot of mold design, manufacturing and debugging, which has high cost and long cycle, and…

In recent years, as people pay more and more attention to environmental issues, automobile manufacturers have been under increasing pressure to improve fuel efficiency. Stricter and more restrictive regulations have brought technical challenges to industrial production and material processing. Among these trends are lower exhaust emissions, lighter bodies and longer service life of parts. The progress in material processing has brought unique opportunities to the field of stainless steel pipe production. Specifically, manufacturers are required to produce such parts. They must have lighter weight, but they must still have anti-corrosion characteristics and meet the strength requirements. In addition, the space…

The random error of machine tool is caused by external conditions and is greatly affected by external conditions. It can be divided into: positioning accuracy error, geometric accuracy error, thermal deformation error and so on. Let's take a brief look at these three errors. 1. Error caused by load deformation of the process system: when turning, the workpiece is often affected by cutting force, clamping force, inertia force, gravity, etc., resulting in corresponding deformation, which eventually destroys the correct relative position between the tool and the workpiece and reduces the machining accuracy of the workpiece. For example, when the stiffness…

As for mechanical design, I believe everyone can read and draw the drawings, but you should also know that the most difficult part of mechanical drawings is dimensioning and technical requirements. So, today, I'd like to introduce some experience that Xiaobian has summed up in his career of mechanical design in the past few years. No more nonsense, empty talk will harm the country, do solid work to prosper the country, and directly start dry goods 1. Remove scale from parts. 2. There shall be no scratch, scratch and other defects damaging the surface of parts on the machined surface…

1、 What is non-standard mechanical design? In short, it is the design of non-standard equipment, non-standard parts and non-standard tooling. For example: C616, C620, C630, c6125, M7475, b650, M131 and other equipment are well-known standard equipment in the machining industry, so there are many special equipment not included in the standard equipment, which is the work goal of non-standard designers. Non standard machinery is a mechanical product that is not finalized. Generally, it can not be bought directly in the market. It should be customized from the manufacturer. The size and shape of machines with the same function may be…

As we all know, machining accuracy refers to the compliance between the actual size, shape and position of the machined part surface and the ideal geometric parameters required by the drawing. Therefore, when we need precision machining, our first response is to find a precision machining equipment, and our inventory of precision machining equipment comes from parameters. In fact, for the definition of this precision, the standards of each country are different. Let's take a rigorous look at those things about accuracy! Accuracy: refers to the closeness between the measured result and the true value. High measurement accuracy means that…

As a widely used traditional material, ceramics is exquisite and durable. However, its hard and brittle characteristics make the 3D printing of ceramic materials more difficult. However, once the application is mature, its benefits are very large. Because the traditional ceramic preparation process can only produce products with simple three-dimensional shape, and the cost is high and the cycle is long. The development of ceramic 3D printing technology makes it possible to prepare complex ceramic products. The advantages of 3D printing technology, such as simple operation, high speed and high precision, have injected new vitality into ceramics. There have been…

5、 Die grinding 1. Importance of die grinding Regular grinding of die is the guarantee of punching quality consistency. Regular grinding of the die can not only improve the service life of the die, but also improve the service life of the machine. It is necessary to grasp the correct grinding time. 2. The specific characteristics of the die need to be sharpened For the grinding of the die, there is no strict number of blows to determine whether the grinding is needed. It mainly depends on the sharpness of the cutting edge. It is mainly determined by the following…

1、 Information from waste The scrap is essentially the reflection of the formed hole. The opposite position is the same. By checking the scrap, you can judge whether the gap between the upper and lower dies is correct. If the gap is too large, the waste will have rough and undulating fracture surfaces and a narrow bright zone. The larger the gap, the greater the angle between the fracture surface and the bright zone area. If the gap is too small, the waste will show a small angle fracture surface and a wide bright band area. The excessive gap forms…
