摘　　要：提出一种实现双转台五轴机床后置处理的新方法。在直线运动的坐标变换和空间圆弧插补中引入了四元数算法,使旋转变换计算更加简洁,几何意义更明确,提高了代码的可重用性。通过限制A、C轴角度增量,对直线进行细分,减小了五轴运动非线性误差,提高了运动精度。A new method was presented for the two-turntable 5-axis postprocessor. The quaternion algorithm was adopted to con-duct the coordinates transformation and space arc interpolation. Thus,the rotation arithmetic was become more visual and the code re-usability was improved. By setting restriction to the A,C axis’increments and subdividing long lines into multiple segments,the non-linear error was reduced.
