Design of automatic pattern laser-cutting system based on DSP control

To achieve high speed clothing cutting with high control precision,the control system for cutting automatically by laser is developed.Taking advantages of digital signal processor TMS320F2812′s rich hardware resources,the system improved laser cutting technology and tangent motion interpolation algorithm.Based on laser cutting principle and general design ideas of auto-cutting system,the mechanical structure with hardware and software is developed for the cutting control system.It involved secure digital card storage and FAT32 file management process,realizing the transmission of files for trajectory control.The results indicated that this automatic laser-cutting system fulfils cutting more exactly and efficiently.Compared with conventional products,it deleted the vibration from mechanical cutter,meanwhile improving the work efficiency and quality for clothing cutting or pattern cutting.
