Design of Control System for Electrolytic Deburring Machine Based on PLC and Touch Screen

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.

Simulation analysis of platform screen door control system in rail transit

“…Once a passenger is hijacked or dragged away, PLC can immediately start the DC motor, stop it from running, and then start it again to avoid the danger of passengers being hijacked. The composition of the platform screen door control system is shown in system figure 1 [7] . This article selects the most common model of shield door motor on the market: brushless DC motor (BLDC), also known as brushless DC motor.…”
