This paper computes and investigate

This paper computes and investigates the effect of fixture compliance and cutting conditions on workpiece stability and uses it as a basis for selecting a suitable fixture among several alternatives. We use two criteria, the minimum eigenvalue of the fixture stiffness matrix and
the largest displacement of the workpiece due to the cutting forces to assess the stability of the workpiece. First, the minimum eigenvalues of the fixture stiffness matrices, for the fixtures being considered, are computed. Second, since the eigenvalues are not dependant on the cutting forces, a displacement measure, the largest displacement of the workpiece due to the cutting force, is computed for each fixture. This displacement is a function of the cutting force and the fixture compliance. The choice of fixture is often a compromise between the two criteria. We also consider the combined influence of fixture compliance and cutting
conditions on workpiece stability. The results from the simple study used for illustration show that the eigenvalues remain constant under different cutting conditions whilst the largest displacement reduces by 68%, a significant reduction.

本文计算和夹具法规遵从性和切削条件对工件稳定性的影响进行了研究，并使用它选择合适的夹具，在几个备选方案中。我们使用两个条件，夹具刚度矩阵最小特征值和由于切削力，评估了工件稳定性工件最大位移。第一，夹具刚度矩阵，对正在审议，该装置的最小特征值计算。第二，因为特征值不是取决于切削力、 位移测量，由于切削力、 工件的最大位移被计算每个夹具。这个位移是切削力和夹具的法规遵从性的函数。夹具的选择往往是两个标准之间的妥协。我们也考虑夹具法规遵从性和切割的综合的影响工件稳定性条件。从这个简单的研究，用于演示结果表明本征值保持不变不同切削条件下虽然最大位移减少了 68%，显著减少。

本文计算了夹具的依从性的影响及切削条件对工件的稳定性和使用它作为在多种选择中选择一个合适的夹具基础。我们使用了两种标准，最小特征值的夹具的刚度矩阵和
最大位移由于切削力，工件工件的稳定性评估。第一，夹具的刚度矩阵的最小特征值的装置，被认为是计算。其次，由于特征值不依赖于切削力，位移测量，由于切削力、工件最大位移，是每个夹具的计算。这种位移是切削力的作用和夹具的依从性。灯具的选择往往是两个标准之间的妥协。我们也考虑夹具符合组合影响切削条件对工件稳定性
