S-shaped machining test has been proposed to ISO standard as an amendment to evaluate the accuracy of five-axis machine tools. However, as the geometric complexity of the S-shape machining test, it's very difficult to predict the influence of error sources on the S-shape machining accuracy. This study proposed a sensitivity analysis method to clarify the relationship between S-shaped machining accuracy and feed axes error motions. The results investigated that how each error motions influence S-shaped machining accuracy. This study could be a fundamental research to illustrate how the errors of feed drive system influence S-shaped machining accuracy.
