摘要
分析了激光飞行标刻过程的扫描幅面约束(SAL)特性以及影响最大飞行速度(MFV)性能的因素。研究了在同-扫描幅面约束下,工件进入扫描幅面的不同方位对最大标刻位移(MMO)值的影响,推导出匀速运动情况下最大飞行速度和最大标刻时间的计算公式,理论公式表明MFV与最大标刻位移值成正比,与标刻时间成反比。对于竖向方位和横向方位进入扫描幅面的工件,采用先进入先标刻(FEFM)扫描算法进行了激光飞行标刻试验,在不同的标刻时间下得到的MFV实验结果和按照理论公式计算得到的MFV值吻合良好。
The scanning area limitation （SAL） and maximum flying velocity （MFV） in laser flying marking system are analyzed. Under the same SAL, the influence of grapics entering into the different direction of scanning area on the maximum marking offset （MMO） is studied. Under the condition of the uniform motion, the relationship between MFV and maximum markable time （MMT） as well as MMO is deduced. For the graphics entering scanning area horizontally and vertically, the experiment of laser flying marking using first entering first marking（FEFM） scanning algorithm is carried out. At different markable time, the experimental MFV value agress well with theoretical ones.
