Development of a Five-Axis Machining Algorithm in Flat End Mill Roughing
… radius formed by tilting a standard flat end mill. The algorithm called Curvature Matched Machining (CM2) is faster and more efficient than conventional three-axis machining [Jensen 1993, Simpson 1995 & Kitchen 1996]. Despite the successes of CM2 there are still many areas available for …

Performance of laser assisted micro-milling (laμmill) of titanium alloy using micro ball end mill
Laser assisted milling technique turns to be complicated and unpredictable when the machining size is scaled to micro level. Furthermore, less has been reported on the application of ball end mill in laser assisted micro milling. This study was carried out to evaluate and clarify the machining …

Prediction of cutting forces in five-axis micro-ball end milling
Five axis micro-ball end milling has been shown as a viable option for machining complex free form surfaces with high aspect ratios and provide micron-scale tolerances. Unfortunately, due to the high fragility of the cutting tool, premature tool failure has been a major challenge in micro-scale …
