Interpreter for Open Architecture CNC System: A Conceptual Model

Conventional Computer Numerical Control (CNC) machines are operated by controllers. Each controller has software model inside known as interpreter. The function of interpreter is to translate input data model code into CNC understandable internal data structure. These conventional CNC controllers are found to be closed in nature and are dependent on vendor specifications. In order to overcome these problems open architecture control systems are introduced. This paper presents an interpreter for open architecture CNC control system. The developed interpreter takes current available Computer Aided Design (CAD)/ Computer Aided Manufacturing (CAM) systems generated International Standard Organization (ISO) 6983 file in text (.txt) format as input and extracts the position, feed rate, spindle etc data from code. Then finally it writes interpreted code in user defined .txt and EXtensible Markup Language (.xml) formats.

Open Architecture of CNC System Based on STEP-NC Data Model

A kind of novel open architecture CNC system is put forward based on the key hardware ‘‘PC+PMAC controller’’. The intelligent CNC system is divided into four layers, the field bus is used in it for openness and interoperability. The system software including several functional modules is developed based on COM for reuse and reconfiguration. The proposed open CNC system is based on STEP-NC data model, which aim to provide higher-level information for process control. The framework presented can be used as a reference for STEP-compliant CNC.

Study on Universal Open-Architecture CNC Development Platform Based on Clipper

An universal open-architecture CNC development platform for further designing all kind of numerical control devices is study, which is beneficial to making considerable reduction of development cycle and cost. The platform adopts IPC+Clipper construction to achieve the open-architecture of hardware, adopts modular programming technique to implement the open software according to user requirement. The control system consists of closed outer position loop and closed inner speed loop.As a result, the combination of position loop and speed loop achieve high precise and good stability of the motion control.

Research of the Series Port Communicate System between PC and MCU Based on Wireless

The paper introduces a Wireless Series Port Communication System between PC and MCU based on the wireless communication module. With the MSComm control technology and the VC++ platform, a PC-side communication software is developed. Hardware and software of MCU-side is also designed by setting serial communication protocols and working modes. The system has been applied in the wireless communication of Open Architecture CNC System successfully.
