Research And Realization Of Programe Preconditioning Technique About CNC Cutting Of Blank

Flat pieces of CNC cutting aviation industry, usually using laser cutting to complete.Two-dimensional projection of two-dimensional digital-analog DXF files for cutting on theCATIA environment from the modulus of the three-dimensional laser scanning measurementsin different ways. Currently laser cutting AutoCAD-based programming, digital to analogfrom different pathways exist coincide lines, large arc lines, broken lines, zigzag lines,ellipses and other defects, but also need to add additional technology and process informationon a number of holes, etc. Manual processing of these defects workload is large, and is easy tomiss some flaws, designed as a pre-treatment system to AutoCAD platform has practicalsignificance.The paper describes the process of development and research status of pre-programmedmaterial handling flat pieces of CNC, the research program for the former two-dimensionallaser cutting the number of mold problems in processing methods, described in detail themethod automatically remove coincide lines, large arc lines treatment, broken lines to findmethods and processing algorithms, researched with a jagged boundary line fitting methodnoise optimization(linear and circular fitting hybrid algorithm), geometric features, such asspecial hole quick study and research ellipse treatment method to add.The paper describes the AutoCAD/ObjectARX secondary development of technology anduse ObjectARX secondary development tools for software developers to achievepre-programmed laser cutting material handling flat pieces of CNC, the guarantee of thequality of laser cutting of blank to solve the relevant laser ablation other issues, reduced theworkload of technical staff to improve business productivity.
