“…Xiao et al conducted extensive research on the optimization design of multistation cold heading process based on Deform-3D [9]. Liu et al [10] used Deform-3D numerical simulation to study the effects of various process parameters on the cold extrusion forming of clutch external splines. Related studies have shown that the design of the heading process and the selection of process parameters are closely related to the forming quality [11].…”

We conduct a study on the thin-wall characteristics of a certain type of A286 thin-walled pipe fittings during the swaging forming process, focusing on the issues of folding and incomplete filling. In order to explore the forming mechanism of defects in thin-wall pipe fittings, the Deform-3D finite element software is utilized for numerical simulations. Through analysis of the forming results, equivalent stress, equivalent strain, material flow lines, and material flow patterns during the swaging forming process, it is found that the occurrence of defects in the thin-wall pipe fittings during the forming process is closely related to the material flow behavior. When the material flows in a positive extrusion manner during the thin-wall feature forming process, the specimen exhibits obvious folding defects. Moreover, there is significant stress concentration occurs in the transition region between the rod and the head.

To explore the application of programmable logic control (PLC) in the automatic control of nonlinear machine tools, the application of PLC in the nonlinear electronic system control is studied. First, the author takes PLC technology in the numerical control machine tool electrical control application as the research equipment, PLC technology in the numerical control machine tool electrical control application is divided into four types. Then, according to the need of management number, the overall structure of PLC is designed and developed, and the concept of operation modularization is adopted to realize the decentralized development of PLC. There are three functional modules: repair, compile, and simulate. Finally, the machining performance of the nc system is evaluated experimentally. The processing time difference of two kinds of machine tools is compared. The average processing time of the original (Numerically controlled) NC system is 3.06 s, and the average processing time of the embedded soft PLC system is 2.01 s, with a gap of 1.04 s between the two systems. The Computer Numerical Control (CNC) machining improvement of 1 s is significant in the processing efficiency of CNC machine tools. The numerical control system embedded in the PLC system is more stable in the machining time, so it can be concluded that the numerical control-embedded soft PLC system has carried on some improvements and upgrades to the operation of machine tools. PLC has relatively strong reliability, stability, and flexibility and is widely used in industrial control systems. In the production process of CNC machine tools, the application of PLC can improve the automatic control level of machine tools. The application of PLC can improve the automatic control level of machine tools and realize the effective control of each link in the production process of CNC machine tools, such as the start-stop program, the automatic replacement of cutting tools in the production process, the automatic diagnosis, and treatment of various faults in the production process, which can be realized through the application of PLC technology.
