Plunge. Lead in. Profile. Lead out. Repeat until reaching final depth. Profile milling does not have to be this inefficient! As you'll see here while machining 4140PH, high-feed ramping with Dapra's indexable tooling allows you to rough in your part profile much more quickly.
By starting directly on the part profile and executing a constant ramp in the Z-axis, you'll eliminate time-wasting entry and exit moves and achieve MRR that rivals high-efficiency milling. All without the cost of solid carbide end mills.
Our high-feed tools are indexable, eliminating changes in part size due to resharpening and providing a low initial cost compared to solid carbide tools. And all of these cuts can be run at identical parameters in long-reach applications with a 2x or 3x length-to-diameter ratio – you aren't restricted by the flute length of your end mill.

The features machined in this demo – hole helix, elongated radial slot, triangular lightening pocket, and 2D contour with a large cutout – are just the tip of the iceberg for what you can achieve with the high-feed ramping approach.
Dynamic milling with a solid carbide end mill is all the rage, but you may be able to match – or beat – those removal rates and save significant money on tooling by ramping with indexable high-feed tooling.
Forget time-consuming starter holes and step cuts. High-feed helixing can shorten cycle times for large-diameter hole making to never-before-seen levels – even on a 40-taper machine.
Detailed instructional video comparing three methods for outside profile contour milling: high-feed ramping, high-efficiency milling and 2D step-down profile milling. See how to program each method, compare cycle times, and view demo footage of high-feed ramping on a Haas 40-taper VM2.
This detailed instructional video compares several approaches to a typical pocketing application: high-feed constant profile ramping (with both an end mill and shell mill) and dynamic milling with a solid carbide end mill. Learn how to program each approaches and compare actual cycle times.
