During the last decades, an increasing use of innovative technologies in manufacturing areas was monitored. A huge amount of physical workload was replaced by the change from conventional machine tools to computer-controlled units. CNC systems spread in current production processes. Because of this, machine operators today mostly have an observational function. This caused increasing of static ...

Until recently, mass producers have relied on long serial lines of dedicated machines in order to machine products at high volumes. Today, as the cost of CNC machining centers decreases, more and more highvolume manufacturers are examining the alternative of shorter lines with more machines configured in parallel. This paper presents the main principles for selecting the right machining system ...

Carney triad is a rare multitumoral syndrome of unknown etiology that was first described in 1977. The neoplasms affect the stomach, lungs, paraganglionic system, adrenal cortex, and esophagus. Approximately 150 cases have been identified. The disorder occurs in young women primarily and is not familial. Multifocal tumors develop in the organs affected.
