Drawling Algorithm Research Of The Cartesian Coordinate Manipulator Based On CAD Document

This paper has developed a mapping function control software in Cartesian coordinates manipulator to enable it to the importation of machinery to control the use of PC CAD graphics into identification, control manipulator in a designated area to set the pace of drawing CAD graphics, but with routing optimization functions.Firstly,according to the company AutoDesk DXF document analysis,VC++6.0 identification extraction of CAD Graphics plans metadata information also extract data optimized. According to extracted data , based on data prepared by the sampling linear interpolation algorithm,circular interpolation algorithm for motion control orders. To avoid the manipulator,the stage stop dithering and the impact of the design acceleration and deceleration function.Mapping the path of the optimal design,according to the TSP traveling salesman problem solving algorithm,made in the system for the shortest path algorithm,the optimal path drawn.Secondly,this paper introduces the Cartesian coordinates manipulator control system,the principle and hardware characteristics,combined with practical application,on the control model and motion parameters settings.Finally,the use of 3-DOF manipulator Cartesian coordinates platform optimized for data extraction , Manipulator mapping and graphics path optimization three aspects of the pilot,the certification part of the algorithm reliability and validity , proved that the three-DOF manipulator Cartesian coordinates NC Mapping function of practicality.
