Tool wear, however, is a dominant and irremovable component in many machining processes, which is a systematic assignable cause. The ordinary measures of process capability are inaccurate because the process data is contaminated by the assignable cause variation. In order to determine the optimal tool replacement time to maintain minimal product quality, conventional capability calculation must be modified.

工具磨损正是制程里一个非常普遍的可归属原因之一，当我们在进行制程能力的运算时应该将此项因素考量进来，否则所得到的制程能力值可能会产生严重的偏差，所以希望能透过修正后的制程能力指标之运用，让我们正确的估算制程能力并且找出合适的工具汰换时机。
