Abstract: The purpose of the current study is to provide a monitoring scheme for evaluating the reliability of drilling of electronic circuit board (ECB) made of FR4 composite materials. The ECB is a ...

Abstract: The anisotropy of fiber-reinforced plastics heavily influences the chip formation and cut quality during machining. Fiber arrangement is found more dominant than the often stressed cutting conditions. ...

Abstract: Polymer-based composite materials are used in a variety of industry. Recently, thermoplastic polymer suitable for the resinous matrix in carbon fiber-reinforced composites has been introduced for ...

Abstract: Laser has been widely used in various industrial applications including machining. However, in shaping operation of composite material after curing, thermal damage associated with laser energy can ...

Abstract: Delamination is the major concern during drilling of composite laminates. Delamination, in addition to reducing the structural integrity of the laminate, also results in poor assembly tolerance ...

Abstract: Composite materials are ideal for structural applications where high strength-to-weight and stiffness-to-weight ratios are required. Currently, linear cutting of composite materials has been increasingly ...
