花样激光自动裁剪系统的DSP控制

为了实现服装面料优质高效裁剪，引入激光裁剪技术，采用具有丰富外设资源的DSP处理器TMS320F2812，运用正切运动插补算法，研究开发了激光自动裁剪控制系统，克服了传统机械裁剪刀具切削引起的震动，不但提高了面料或花样裁剪的质量，而且也提高了裁剪效能。在激光裁剪的原理和自动裁剪系统的总体设计基础上，完成了结构设计和硬件设计，同时配合软件设计，应用SD卡存储及FAT32文件管理程序实现轨迹控制文件的传输，结果表明：激光自动裁剪具有高精度高效率的裁剪效果。

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.
