Application Of Transmitting Energy Fiber On Laser Carving And Software Study About Graphics

Laser, rising in early sixties of 20 century, has affected many fields because of its homochromy, high lum and straight direction. In recent years, laser engraving, as high-tech product based on computer numerical control, emerges in market which has abroad application and numerous requirement.Current laser engraving adopt holophote optical circuit or libration mirror which have some defects such as engraving small, photic circuit complex, adjust difficult or facula size asymmetry. We presents a new laser engraving that use transmitting energy fiber as energy transmittion system. It couples energy in transmitting energy fiber, then engrave by moving fiber. Thereout resolve the problem of deflexion and stabilization and make the carving-line uniform, power invariable, graph slick and suit large-scale engrave. This paper first introduces transmitting energy fiber, constitutes of engraving system, software and hardware design, laser machine theory and interpolation arithmetic.This paper expound software study about graphics. Software applied in laser carving is special. Current software such as AutoCAD and Photoshop are used on computer or printer, inapplicable to laser carving. Because of commerce and patent, the software of manufacturer is kept secret. So there are not software ready for reference. The application of software is correlative with hardware, therefore special software for new-style laser carving is necessary. This paper accomplish software design, write the program and implement along-curve engrave. The software includes graphics disposal and output control. Graphics disposal comprises drawing and handling of basal graphics, read and write of metafile with PLT format. Output control comprises interpolation, the movement of electromotor and on-off of laser.
