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 pre-drilling 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.
