Drill, Ye Tarriers, Drill!

States near the Marcellus Shale, a huge natural gas formation centered in Pennsylvania, are feverishly pursuing a $4 billion ethane "cracker" to be built by Royal Dutch Shell. The cracker will process ethane-rich gas from the Marcellus Shale into ethylene, and the ethylene will be used by the pharmaceutical, chemical and plastics industries. The plant will create 10,000 construction jobs and several hundred permanent jobs.

Soft machine

Robust and stiff often come to mind when considering the characteristics that make for a productive milling machine. However, Juanjo Zulaika, a researcher at the applied-research center Tecnalia Research & Innovation, thought otherwise and developed a "softer" milling machine with reduced weight and stiffness. That's achieved while increasing productivity.

Plunge Milling Improves Metal Removal in Deep Machining

Significant progress in metalworking productivity most often results from the combined efforts of toolmakers, machine tool builders and software developers. Plunge, or Z-axis, milling is a good example.
