Abstract
In the process of machining parts, burrs are hard to avoid. Electrolytic deburring method can obtain high homogeneity and surface quality, which is suitable for metal burrs in complex inner chambers. Therefore, it is widely used in automotive engine, aerospace, pneumatic and hydraulic industries. Electrolytic deburring process is affected by many factors, and its control system design is particularly important. Based on the principle of electrochemical deburring processing and PLC control technology, designs a set of electrochemical deburring machine tool control system, through the analysis of the processing technology and design the PLC closed-loop design idea algorithm and software running flow, through the configuration software design the control system of the human-computer interaction interface, in combination with the RS - 422 bus technology to realize processing parameters and data transmission and processing. According to the characteristics of the deburring machine, an adaptive control system is developed. Specific work includes: machine tool control system requirements analysis; hardware circuit design and communication design; PLC program design and man-machine page design; anti-interference design from both hardware and software aspects; field debugging of the control cabinet to improve the system function. The test results show that the machine tool is stable and reliable, and the deburring effect is very good.
Highlights
In the process of cold metal cutting, the phenomenon of grain shear slip and plastic deformation occurs in metal parts under the action of cutting force
Ming Li: Design of Control System for Electrolytic Deburring Machine Based on PLC and Touch Screen upper and lower limits of the set range, the two alarm outputs are effective
Workpiece is connected with the positive pole in the electrolytic deburring process, and the tool is connected with the negative pole
Summary
In the process of cold metal cutting, the phenomenon of grain shear slip and plastic deformation occurs in metal parts under the action of cutting force This phenomenon will cause the material to be extruded and teared, and the sharp corners and bristles, i. The control system is the CPU of the whole machine tool, which is responsible for coordinating the work of each part of the equipment and controlling the processing parameters in the process of processing, so that the processing process can proceed steadily and orderly. These six parts are independent and interrelated. In the process of deburring, the control system plays a coordinating role of process actions and the monitoring role of process parameters, which is an essential part of the electrolytic deburring machine tool
