The drilling module is simply ingenious, because 5-axis helical drilling becomes as simple as helical tilt milling. The milling cutter is tilted forward in the direction of motion, and a second inclination helps to avoid collisions with the bore wall.
This strategy is excellent for making an opening cut when roughing deep cavities. Moreover, no predrilling is required. Removal of material from circular pockets is particularly effective while putting very little strain on the milling cutter. With thanks to this 5-axis simultaneous machining strategy, another benefit is the ability to use non-centre cutting milling tools.
