Based on the requirements of a machine tool which is used to measure and process aeronautic structural parts, a three-axis simultaneous control system with dual-CPU structure (Galil motion controller and industrial computer) is presented in this paper. The core of the system is the GALIL motion controller, and the human-machine interface, data processing and real-time monitoring functions are realized...
To meet the need of advanced manufacturing technique, an open computer numerical control (CNC) software package for CNC machining is developed. Module library of the software package was of tree structure with a depth of 5. Terminal nodes of the tree were module units with unambiguous functions. Module units which dealt with real-time tasks were developed adopting real-time dynamical linked library...
The current 5-axis coordinated linear interpolation method results in low-speed, low-accuracy and enormous numerical control (NC) files in sculptured surface machining. An instruction format with AKIMA spline curves suitable for 5-axis coordinated real-time interpolation is presented by making use of the advantages of AKIMA curves to represent spatial curves. Curve through position vectors in the...
In this paper, a motion controller for computerized numerical control (CNC) machining is developed in accordance with open modular architecture controllers (OMAC) agreement and industry standards. The motion controller is a software package running on personal computer. It is developed based on modular structure adopting hierarchic organization mode. After analysis of software and hardware structure...
