Study of the local forces along a drill edge – comparison of two methodologies [PDF]
, 2013 In aerospace applications, drilling is one of the most common operations. However, this machining stays complex and expensive, especially in hard to cut materials. Because of the closed aspect of the operation, the measure or evaluation of the phenomenon
