Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Analysis on the experimental environment and process of automobile simulation

 

The mechanical car simulation test bed was later developed to test the overall product. A gear-chain drive is used to divide the circumference of the drum into six areas at equal distances. Tiles may be placed on each area, and the shape of the tiles is also more complicated. What is placed on the wheel drum is a trailer or a two-axle car.

To simulate vibration correctly, not only does the simulation platform produce a random vibration that is consistent with the actual amplitude distribution, but the acceleration power spectrum density diagram also conforms to the test conditions, which is simply impossible on a simple mechanical simulation platform. By adjusting the rotation speed, the shape and placement of the tiles on the wheel drum, the load on the trailer and other factors, so that the following five indicators are consistent with the actual measurement, it is considered that the field transportation test environment has been moved to the laboratory for simulation. The five indicators are:

(1) The average value (mathematical expectation) of the peak (or valley) random variable recorded by the simulation table vibration is equivalent to the actual measurement.

(2) The first moment (variance) test of the peak value is equivalent to the actual measurement. (1) and (2) Two, indicating that the peak random variable of the analog station is in the same distribution as the actual measurement.

(3) The main frequency range on the acceleration power spectrum, the test is equivalent to the actual measurement.

(4) The power spectral density value at the main frequency) G1 (f) and G2 (f), the test is equivalent to the actual measurement. (3) and (4) Two, indicating that the energy concentration in the main frequency range is consistent.

(5) The root mean square acceleration value of the acceleration time history, the test is equivalent to the actual measurement. This indicates that the total power given to the test piece by the simulation platform is consistent with the actual measurement.

Due to the lack of proper mathematical description between the above five indicators and the debugging parameters, there is a lot of blindness in the process of debugging and the workload is heavy. It often happens that this indicator is met, but another indicator is not met.
