When combined with high-performance indexable milling tools, constant ramp profiling (contour ramping) can be a highly effective alternative to dynamic/high-efficiency milling – at a tooling cost that is much lower than solid carbide round tools.
In this demo, we examine three approaches for machining a 1" deep x 3.5" wide x 6" long pocket in 4140PH (28 Rc), comparing both cycle time and tooling cost.
1 – High-Efficiency Milling – Solid Carbide End Mill
2 – Double-Pass High-Feed Ramping – Indexable End Mill
3 – Single-Pass High-Feed Ramping – Indexable Shell Mill
