At present, most domestic high speed molybdenum wire cutting machine tools do not perform systematic and comprehensive process tests and establish a corresponding process database. Various types and specifications of high-speed wire cutting machines are incompatible from hardware to command codes, and there is no unified standard for them. Moreover, due to the different boundary conditions of the machine tools, the r

Using molybdenum cutting wire or brass wire China’s high-speed molybdenum wire-cut WEDM has made great progress, but there has been a tendency for heavy equipment and light processes, resulting in backward technology. (l) The selection of line cutting process parameters still largely depends on the operator’s experience, or approximate selection based on the process parameter table, and the process parame

BP (Backpropagation) algorithm is an effective algorithm, its model has become one of the important models of the neural network。 The BP network is a unidirectional propagation multi-layer feed-forward network consisting of an input layer, an output layer, and an implicit layer (which can be one or more layers). The BP neural network for molybdenum wire-cut EDM is the input layer and the input layer is four. Units: w

Due to the randomness and complexity of the molybdenum wire cut EDM process, it is difficult to establish a precise mathematical model between process parameters and process effects. It is very difficult to study the machining process with traditional methods. The research on the Thousand Processes is not deep enough to improve the quality of the processed products and the processing efficiency is low, which seriousl

With the development of computer technology, the function of the computer to solve the mathematical model of the complex system is becoming stronger and stronger. The mathematical simulation (also called numerical simulation) of the system using computer has been paid more and more attention by people and has been widely used. The time required for the simulation test is much shorter than the physical simulation, and

Cutting trajectory anomaly and elimination methods The cutting trajectory deviates from the machining pattern and generally occurs when machining program programming errors or digital program control deviations occur. The abnormalities of the cutting trajectory that occur in addition to the machine control and programming errors can be discussed in the following two aspects. (1) The electrode wire does not return to

Trouble shooting in WEDM using molybdenum wire or brass wire Trouble shooting principles (l) First outside and then inside. The development of wire-cut EDM technology is very mature today. The machine tool structure and the control circuit of the electrical control box are generally free of problems and lead to the failure of spark wire cutting. Therefore, in the process of diagnosis, it is necessary to start from th

The surface quality of the wire-cut electric discharge machining is closely related to the servo feed control. If the servo feed control system has poor performance and improper operation, it often occurs with fast feeding, slow down, short-circuit back and forth, and even frequent broken wires ( molybdenum wire or brass wire ). At this point, the quality of the processed surface is definitely not good. In order to i

Process Method for Improving the Surface Quality of Wire Cutting EDM Using molybdenum wire electrode or brass wire 1.Using narrow pulse width precision processing The use of narrow pulse width precision quasi-machining is an effective process for obtaining the required surface quality. As we all know, whether it is a low-speed wire(molybdenum wire)feeder or a high-speed EDM wire feeder, high cutting speeds can be ach

1) Clear angel wire cut processing method using molybdenum wire or brass wire (I) The processing method for punch punching are relatively simple. When cutting to the top of the corner, continue to cut forward along the original cutting direction by a certain distance (approximately 0.5 mm longer cutting length), then use this distance (approximately 0.5 mm) as a radius, and follow the arc to the other side of the cor
