Abstract
CNC(Computer Numerical Control) machine tool is the foundation and core of modern manufacturing systems, advanced CNC technology is the key to sustainable development of machine tool manufacturing industry. This thesis presents ARM as the main chip, motion control chip MCX314, the operating system using μC / OS-II, to build a CNC system development hardware platform and software platform, to explore the new ways for numerical control system development and design. This thesis can be divided into: CNC system hardware platform structures, including ARM and external hardware selection, hardware interface design and testing; MCX314 hardware platform design and testing; Software Platform, including the use of real-time operating system μC / OS-II to achieve the mission of the NC system, scheduling, management, μC / OS-II transplantation on ARM; MCX314 hardware platform building and testing; application framework built , program design and testing. Test results showed that: ARM as the main chip, MCX314 as a motion controller of the CNC system is feasible, its motion performance can meet the design requirements.
