分析了机床各构件之间的相对运动，并以此为根据，建立了用齐次变换矩阵的乘积来表述机床运动的形状创成函数。应用这一数学模型，可以求出几何误差对机床加工精度的影响。
Based on the analysis of the relative movement between the components of the machine tool, the product of homogeneous transformation matrix is used to describe the shape creation function of machine tool movement. Application of this mathematical model, you can find out the impact of geometric errors on the machining accuracy.
