This study includes a review of these studies, a categorization of similar ones and detailed information about measurement systems. Through the review of studies, we ...

Zigzag pocket machining (or 2D-milling) plays an important role in the manufacturing industry. The objective is to minimize the number of tool retractions in the zigzag machining path for a given pocket (i.e., a planar domain). We give an optimal linear time dynamic programming algorithm for simply connected pockets, and a linear plus O(1) time optimal algorithm for pockets with h holes. If the...

Electrical discharge machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and a work piece in the presence of a dielectric fluid. Aluminium metal matrix composites (AMMCs) refer to the class of light weight high performance aluminum ceramic material systems. The reinforcement in AMMCs could be in the f...
