Thin wall machining
The machining strategy for thin wall sections should vary depending on the height and thickness of the wall. The number of passes will be determined by the wall dimensions and axial depth of cut.
This process uses high-speed techniques, i.e small ap/ae and high vc, facilitating milling of thin walls, to then reduce the time of tool engagement and consequently the impulse and deflection. Step support machining the wall in overlapping passes is used when the ratio of wall thickness to height is 15:1 to 30:1.
