In order to promote the high frequency performance of open architecture CNC system, an embedded CNC controller combining FPGA (Field Programmable Gate Array) technology and real-time Ethernet communication bus was designed, which consisted of an embedded ARM (Advanced RISC Machines) processor and an FPGA. An open source CNC software running under Linux operating system was customized to accommodate...
The Computer Numerical Control (CNC) in manufacturing brings advantages like faster, smoother and easer machining of curves, complex 3-D dimensioned profile. Primitive CNC machine tools could not compromise on product quality and process efficiency. The ability to monitor and control multiple process modules increases productivity, improves the quality of products and enhances prognostic capability...
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...
The embedded and field-bus technology have a profound impact on industrial control area. The paper design an embedded numerical control (NC) system based on ARM, the embedded NC system has the characteristics of high precision, low cost, good openness and so on. Through extend CAN bus interface circuit on ARM which can realize the network of embedded NC system. The network for embedded numerical control...
The embedded module network numerical control system is demonstrated in the paper applying the latest development of embedded technology, network and communication (including industry network and communication technology). Besides, the modular development of the systempsilas software and hardware platform is demonstrated with details. By exploiting the modular design method, the embedded module network...
The industrial sector manifests the necessity of a flexible, efficient and reconfigurable platform to attend the diverse applications in mechatronics. The main difficulty to work with this kind of processes is the necessity of real-time control systems of high performance. The design of an FPGA based platform is presented in this work, which gives support to the research and development of products...
Although work has been carried out on fault diagnosis of general computer numerical control system, there have been few papers which focus on fault diagnosis of special computer numerical control system of roll grinder. In order to satisfy higher grinding accuracy and roll shape lower error of roll grinder. In this paper, Rough Set and Dempster-Shafer Theory as a new fault-diagnosing tool is used...
