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

Figure 6 – 5 (a)   False  (b)  Correct (2) Use closed cutting with a threaded hole. When punching parts such as punches, it is customary not to consider punching through the holes, but to cut them through a lengthy induction program from outside the material boundary. This operation is very convenient, but is easily affected by the internal stress of the material. In some occasions where the precision of machining is

Using molybde molybdenum wire num wire or brass wire 1. Process for improving dimensional accuracy Prior to Wire cutting EDM, the workpiece material has been subjected to overheating and cold working, and there is a certain amount of stress inside the material. Even if the over-annealing process is performed, various stresses will appear during the on-line cutting process, and the workpiece will deformed, thus affect

People’s concern about the electric spark wire cutting plus T-members, includes machining accuracy (size accuracy and shape accuracy) and surface quality (surface roughness, cutting stripe and surface texture change layer) of the processing part. Although many factors affecting the WEDM processing accuracy and surface quality have been discussed in detail in the 3rd chapter, how to deal with it in production practice
