Influence of interpolation type in high-speed machining (HSM) [PDF]
, 2014 The recourse to the high-speed machining for the manufacture of warped shapes imposes an evolution towards a very high technicality of the CAM methods and of the machining operation execution. Due to its own characteristics, the high-speed machining (HSM)

An efficient NC tool path planning approach [PDF]
, 2005 One major problem encountered in NC machining is that cutting load fluctuates in twisty tool paths and increases momentarily when milling concave corners where stock material concentrates.

Simulation of the deflected cutting tool trajectory in complex surface milling [PDF]
, 2011 Since industry is rapidly developing, either locally or globally, manufacturers witness harder challenges due to the growing competitivity. This urges them to better consider the four factors linked to production and output: quality, quantity, cost and

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]
, 2009 In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,
