Faster ,or slower for the tracking cutting status of Wire cutting ,either of which will have an influence on the cutting speed ,surface roughness of workpieces and processing stability . Under the circumstance of the same high power and processing material , sometimes the surface of finished workpieces are clear and bright ,very delicate, still other time black and rough . This is because spark discharge must produce

Some simple and special assistant tools are used in order to improve machining efficiency in the process of high-speed wire cutting . 1)Wire feed tool 1 : As chart9-2 shown, a Φ2mm steel wire is used and bent caudally, a little groove in an inverse V type is cut by wire . This tool is mainly used to make electrode wire gone through the wire hole from top to bottom . Electrode wire is firstly embedded into the little

For each of the curves in Figure 6-17, after the pulse parameters are determined, there is always an optimal workpiece thickness value that corresponds to the maximum value of the cutting speed of molybdenum cutting wire. When the workpiece thickness is at the optimum value, the pulse discharge efficiency is the highest, the workpiece thickness is too small or too large, and the cutting speed is reduced. When the wor

using molybdenum cutting wire The large number of large-thickness parts put forward higher requirements for molybdenum wire -cut electric discharge machining. General high-speed thread cutting machine is only suitable for processing workpieces with a thickness of 100mm or less. When the workpiece thickness exceeds 100mm, the processing stability is degraded, and the machining accuracy and surface roughness cannot mee

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
