Abstract :
A wheelset disassembly machine is newly designed for dismounting wheelsets using a double-side disassembly technology. This NC machine tool integrates such functions as hydraulic controlling, mechanism positioning and process monitoring with a user-friendly Human-machine interface (HMI). A control system using Siemens S7-200 series PLC is introduced to accomplish these functions. After analyzing three main architectures of PLC-based control systems in NC machine tools, this paper presents details of the machine´s control system design and PLC program. Especially, the communication mode and protocol between PLC and master computer is discussed.
