Electrical discharge machining system and control method thereof

Abstract

The invention discloses an electrical discharge machining system and a control method thereof. The electrical discharge machining system comprises an electrical discharge machine and a communication terminal, and the electrical discharge machine is provided with a control module, an authentication module and a communication module; the authentication module is used for verifying identity information of a machine operator to judge whether the machine operator leaves the machine; when the authentication module receives authentication information, the control module is used for comparing the authentication information with the prestored identity information of the machine operator; if the comparison is successful, confirm that the machine operator leaves the machine; and at the moment, the control module communicates with the communication terminal through the communication module so as to send information to the communication terminal and / or receive the information emitted from the communication terminal. According to the electrical discharge machining system disclosed by the invention, the machine operator can grasp the dynamic state of the machine under the condition of keeping faraway from the machine in time, in favor of saving the labor hours and the working hours of the machine.

Description

technical field [0001] The invention relates to the technical field of electrical discharge machining, in particular to an electrical discharge machining system and a control method thereof. Background technique [0002] EDM machine tools play a very important role in the field of mechanical manufacturing (especially in the field of mold manufacturing). They are often used to process various complex cavities, especially for machining cavities on workpieces of difficult-to-machine materials. [0003] However, EDM machine tools are prone to abnormal discharge states such as short circuits and arcs during processing, especially in deep cavity processing. Once such discharges occur, the machine tool will suspend processing and give an alarm. If the machine operator does not intervene in time, It will seriously affect the production schedule. In addition, because the removal of material by EDM is a process in the microscopic field, the material removal rate is relatively low, wh...

[0003] However, EDM machine tools are prone to abnormal discharge states such as short circuits and arcs during processing, especially in deep cavity processing. Once such discharges occur, the machine tool will suspend processing and give an alarm. If the machine operator does not intervene in time, will seriously affect the production progress

In addition, because the removal of material by EDM is a process in the microscopic field, the material removal rate is relatively low, which also determines that the processing efficiency of EDM machine tools is low, and it takes several hours or even ten hours to process the cavity. a couple of hours

Therefore, during this long processing time, machine tool operators often dare not leave the workshop, or even stay away from the machine tool, but in most of the time (sometimes during the entire processing process), the discharge state of the machine tool is normal, and there is no need to perform maintenance on the machine tool. Intervention, which results in a serious waste of labor

[0004] In addition, once the machine tool starts processing, it needs to continue until the processing task is completed. Therefore, the machine tool operator is often still working after work. If the machine tool operator leaves the workshop, he will not be able to grasp the status of the machine tool and the progress of the processing task in time. In the event of an abnormal discharge state, it is impossible to return to the workshop to intervene in time, and it is also impossible to shut down the machine tool or replace the workpiece in time to start the next processing task after the previous processing task is completed, which will undoubtedly cause a waste of man-hours for the machine tool
