摘　　要：龙门铣床的横梁由于承载自身和主轴等关键零部件的质量,会产生严重变形,影响其几何精度,进而影响工件加工精度。因此,文章通过对横梁进行加工工艺补偿,来提高横梁的直线度。利用ANSYS Workbench对龙门铣床横梁进行静态特性研究,分析主轴在不同位置时横梁的最大变形区域和最大变形量,并以此为基础进行工艺补偿。借助激光干涉仪测量工艺补偿前后横梁的直线度,测量结果显示工艺补偿后横梁的直线度误差降低了90%,证实了工艺补偿对提高横梁几何精度的有效性与可行性。Because the beam of the gantry milling machine bears the quality of key components such as itself and the spindle,it will have serious deformation,affecting its geometric accuracy,and then affecting the workpiece processing accuracy.Therefore,the paper improves the straightness of the beam by compensating the beam processing technology.ANSYS Workbench is used to study the static characteristics of the beam of the gantry milling machine,analyze the maximum deformation area and the maximum deformation amount of the beam at different positions of the spindle,and make process compensation on this basis.Laser interferometer is used to measure the straightness of beam before and after process compensation.The measurement results show that the straightness error of beam after process compensation is reduced by 90%,which proves the effectiveness and feasibility of process compensation for improving the geometric accuracy of beam.
