The implementation of a modular open architecture PC-based CNC system used as a research and education equipment
Journal Title: Proceedings in Manufacturing Systems - Year 2017, Vol 12, Issue 2
Abstract
Open-architecture CNC technological equipment are used nowadays both for industrial and educational purposes. Using a modular structure and a PC-based CNC controller, these devices allow the users to develop and test new control and machining strategies, to train in the field of CNC programming and CAD/CAM techniques, while keeping the costs as low as possible, in comparison with the industrial, closed architecture, CNC machine-tools. However, the modular, reconfigurable, structure and consequently the modular assembly method, comes with some drawbacks, most of them related the accuracy of the system. Also, PC-based open architecture controllers lacks some important features linked with 4&5-axis indexed machining and 4&5-axis continuous machining, which normally are present in industrial CNC controllers. Among these features, the ability to use local coordinate systems and the ability of using tool center point management are the most important, and their absence makes the use of CNC machines with PC-based open architecture for multi-axis machining quite difficult. This paper present the implementation of a 5-axis modular CNC machining center, built in a modular way and using LinuxCNC as PC-based CNC controller. Some methods for improving the accuracy of the equipment and strategies to overcome the difficulties related to 4&5 axis machining are presented.
