The role of insert geometry in minimizing the cost of milling operations-II
January 12 2014 -
In milling, as with all manufacturing operations, if a machine tool isn't working, it's not earning any money. Understandably then, machine shops and machinists push for the highest possible metal removal rates, but this won't necessarily minimize costs.
The concept of using a combined gas turbine and steam (COGES) plant for merchant vessels, and LNG carriers in particular, was first announced by GE at The Motorship’s 2013 Gas Fuelled Ships conference and featured in our December issue.
The role of insert geometry in minimizing milling costs - I

Getting more life from cutting inserts is the key to minimizing costs, especially in milling operations. While it’s natural to focus on maximizing material removal rates, higher speeds can mean earlier and less predictable failure.

German steam power plant boasts 46% efficiency and 750MW output
December 17 2013 -
The Lünen hard-coal-fired power plant owned by Trianel Kohlkraftwerk Lünen GmbH und Co. KG has been built as a turnkey unit under a consortium arrangement between Siemens and IHI Corporation. It has an installed electrical capacity of 750 megawatts. With 7,000 full-load operating hours predicted for 2014 the Lünen plant can provide electricity for around 1.5 million households. It also supplies the city of Lünen with district heating. With an efficiency of almost 46 percent, Lünen lies on the Datteln-Hamm Canal, a major inland waterway in North-West Germany.
Wood Group GTS has appointed Mike Fisher to the new position of president of its US oil, gas & industrial services (OGIS) business.
