Abstract: Aiming at the complex operation with low cutting precision and the poor control connector scalability of traditional metal band sawing machine, the induction to cut requirements for metal band sawing was made. The control system based on ARM and CPLD technology was proposed, and the selection of the main components, the control system of the power distribution circuit, the control interface of the software and the control of the work process were designed. The metal belt cutting size and system response time was tested by CNC cutting test bed. The experimental results show that the control system which can display and control the running state of sawing machine at real time is a set of advanced, novelty, practical control system with the advantages of automatic processing, high cutting precision, stable running and extensible multichannel interface.
