This paper reviews real-time (RT) Ethernet and discusses special requirements for numerical control (NC). Then such a real-time Ethernet - EtherMAC (Ethernet for Manufacture Automation Control) is presented. EtherMAC uses master-slave communication structure. The master device supports standard Network Interface Card (NIC), and the slave device has a(More)
Surface roughness and surface shape simulation are presented for the intelligent STEP-NC turning controller in this paper. Simulation models for surface roughness and surface shape were established. Graphic user interface (GUI) was developed to input the simulation parameters and output the simulation results. Simulating with the developed simulation(More)
The current automotive electrical/electronic (E/E) systems are characterized by proprietary solutions, which seldom allow the exchange of applications between both automotive OEMs and their suppliers. It is especially difficult to change ECU suppliers or reuse the software in a new generation of products. Increasing functional requirements in automotive E/E(More)
High efficiency and low cost have been the focus of embedded system development, and computer numerical control (CNC) system based on PC and Windows operating system is the main stream of open-architecture system. The characteristics and requirements of open-architecture CNC system is introduced briefly. A new method that develops the open-architecture CNC(More)
Embedded control systems play a very important role in the modern industry, which fulfill various complicated and durable control tasks in automation industry. A typical embedded control system consist of a microprocessor based hardware and a set of software running on top of it. Due to rapid upgrading and function changing, the life cycle of embedded(More)
With the new emerging technologies of high performance machining and the increasing demand for improved machining accuracy in recent years, the problem of thermal deformation of machine tool structures is becoming more critical than ever. The computer numerical control (CNC) turning system for noncircular section pistons is designed with giant(More)
