Modeling of hard part machining: effect of insert edge preparation in CBN cutting tools

High speed machining of hardened steels for manufacturing dies and molds offers various advantages, but the productivity often limited by mainly tool life. This study investigates the influence of edge preparation in cubic boron nitrite (CBN) cutting tools on process parameters and tool performance by utilizing practical finite element (FE) simulations and high speed orthogonal cutting tests. T...

The Effect of a Glass Ceramic Insert in Sandwich Technique on Microleakage in Class II Composite Resin Restorations

Introduction: The aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class II composite resin restorations. Methods: Sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). Class II box-only cavities were prepared in distal aspects of each tooth with gingival margin located a...

Using Sentinels in Insert Sort

Although insert sort takes quadratic time in the worst case it has a very efficient inner loop. Its bestcase computing time is linear, which occurs when the data are already in sorted order. It is the method of choice for data stored in linked lists or small arrays. Algorithm 1 is typical, and is written in extended Pascal. Implementing the conditional 'cand' operation (to guard against the err...
