Abstract


Laser cutting is an emerging thermal cutting way , has the advantages of high-precision , high efficiency , low pollution , has become one of the hot thermal cutting technology development . In order to meet the requirements of laser cutting equipment, automation, high precision and control mode digitizing , etc. , in support of major science and technology projects of the Shanghai Municipal Science and Technology Commission of light , research and development with independent intellectual property sheet laser cutting CNC system software to meet the requirements of the development of China 's laser cutting technology . This article analysis and comparison of currently used based PC CNC system architecture and real-time operating system based on the use of the full software CNC system based on ServoWorks CNC system platform architecture and multi-task scheduling analysis and data conversion , coordinated and efficient work has laid a good foundation for the cutting machine CNC system function modules . Developed a more complete cutting machine CNC system software , and a special process for laser cutting , CNC machining path automatically generated , including rollback , Recovery and list point curve cutting path automatically generated . The rich cutting machine CNC system function, improve the level of automation of laser cutting equipment . Cutting machine automatic programming of the NC program , a detailed account of the principle of parametric graphics library , manual nesting and DXF file parsing and converted three graphs automatic programming function module and the design and implementation of methods to shorten the preparation of parts machining program cycle. Laser processing parameters on the cutting quality analysis model of the energy distribution of the incision , the power density optimization of power - speed matching model , the development of numerical control system of the power control module according to the process of cutting the energy balance equation , adaptive laser power control functions integrated into the sheet laser cutting CNC system . Finally , the contents of the research summary and outlook , in-depth research and development of laser cutting CNC system provides a certain reference .
