摘　　要：基于环形铣刀在五轴加工中建立的几何运算数学模型,通过MATLAB试验分析了刃倾角、曲率半径、残留高度和变形误差对有效切削域的影响。运用本文的研究结果,可以选择合适的刀具位置姿态,使环形铣刀在刀触点位置的有效切削域最大,从而提高加工效率。通过调整刀具姿态使刀触点处由切削力引起的变形误差减小,以保证加工质量。Based on the model and by MATLAB experiment, the effect of inclination angle, curvature radius, scallop height and deformation caused by cutting force on the effective cutting domain are analyzed. With the application of the re- search results, the appropriate tool position attitude can be selected, So that the ring cutter in the knife contact position of the effective cutting area maximum, thereby improving processing efficiency. By adjusting the tool attitude so that the knife contact at the cutting force caused by the deformation error is reduced to ensure the processing quality.
