Orthogonal cutting force measurements and single-point tool life tests were conducted in order to analyze the sensitivity to heat treatment on the machinability of three titanium alloys: Ti6Al4V, Ti-5Al-4V-0.6Mo-0.4Fe (TIMETAL 1 54M), and Ti6246. The Ti6246 alloy showed the highest tool wear rates and the higher cutting forces in all the heat treatment conditions which could be related to its higher mechanical properties. TIMETAL 1 54M alloy, a newly developed alloy with similar mechanical properties to the more commonly used Ti6Al4V, showed the lowest wear rates. Microstructural changes due to heat treatment have some influence in the machinability of the alloys. The b annealed samples of the Ti6Al4V and TIMETAL 1 54M alloys, with a very coarse lamellar microstructure, showed considerably shorter tool life and higher cutting forces. The rest of the heat treatments showed no significant influence in the machining behavior of the analyzed alloys as they do not cause important microstructural changes.

are experienced specialist practitioners in workplace consulting. Peter Osborne of PA Consulting Group has a wide property and construction background and has published a number of articles on workplace subjects. Stephen Bradley is an architect and the Director of The Workplace Forum, an international think-tank, research and learning group of major corporate and governmental occupiers of business accommodation, brought together by the architects and workplace consultants DEGW. The Workplace Forum focuses on the implications of emerging workplace issues, producing a wealth of case study-based knowledge in this field. ABSTRACT Many organisations have increased collaborative performance by introducing new technologies and new processes; by integrating these with innovations in the working environment they can catalyse additional andsustained improvements in collaborative performance. If planned, designed and managed as an integrated system encompassing people, process and place issues, the workplace environment can be a powerful catalyst for business change.

A proposed new digital hierarchical technology roadmapping architecture can integrate and align research activities with the manufacturing capabilities needed by industry.
