Sandwiched materials machining
SANDWICHED MATERIAL MACHINING
Boring 4.75-mm holes in a sandwiched panel made of carbon and titanium. When used to monitor the machining of layered composite materials with unknown thicknesses, the WattPilote system detects each transition from one material to another and enables adjustment of the cutting conditions (feed and speed) to match the material.
Digital Way is the patentee for this method, which is based upon the power derivative. It is independent of no-load power, tool wear, and homogeneous variations in part hardness. It is also fast and reliable. The WattPilote system is appropriate both for orbital boring/drilling and also for traditional boring operations. It optimizes the feed rates as well as the cycle times and therefore it becomes an important part of overall machining quality.
