Design of Open-architecture Gantry Milling NC System Based On Motion Control Card

摘要

The open-architecture control system is designed to realize the accurate motion control of gantry milling machine in this article. The hardware construction of control system adopts "industry PC + Clipper motion control card" architecture to achieve the opening and modularization. The Full coordination method is selected by assigning two motors of the gantry system to the same axis in the same coordinate system. The function modules of control software are demonstrated. It is programmed based on Visual C++ and Pcomm32 pro DLL library. The design of the gantry milling control system can realize the opening of architecture, and more accurate, smooth motion control of 4 axes.
