Constant ramping with a 90-degree shoulder mill is a great technique for easy, efficient long-reach profiling with good surface finishes – even in the roughing cut.
Check out this demo for a peek at this approach using an EDGE² DSS series shell mill.
3D milling involves a variety of tools and tool paths. In less than 5 minutes, this video demonstrates three different 3D shapes, what tools DAPRA recommends for machining and some suggestions for tool path generation for each.

If you’re milling at less than 50% of your cutting tool diameter, you can minimize your cycle time – and maximize productivity – by properly adjusting your programmed feed per tooth.
Find out how to leverage radial chip thinning.
This quick contour milling demo illustrates how you can match the metal removal rates of high-efficiency milling with a solid carbide end mill – and save significant money on tooling – by ramping with an indexable high-feed tool.
Check out the advantages of high-feed ramping over high-efficiency milling.
In this detailed instructional video (16 min 45 sec), we look at some unexpectedly efficient options for mold core roughing and finishing.
Have you considered that a button cutter might actually be a great choice for high-feed mold core ramping? We also compare options for finishing the part, comparing bull nose to ball nose cutters and waterline profiling to plunge finishing.
Check out these interesting methods for ramping up your profitability.
A solid approach to quickly and accurately milling a deep chase pocket can be a big money-maker for mold shops. Here, we look at a good option for roughing, semi-finishing and finishing the walls and floor of a deep, straight-walled mold insert pocket.

Detailed instructional video (11 min 14 sec) comparing three methods for outside profile contour milling. See how to program each method, compare cycle times, and view demo footage of high-feed ramping on a Haas 40-taper VM2.
See how high-feed ramping measures up.
Detailed instructional video (15 min 42 sec) comparing high-feed ramping to high-efficiency/dynamic milling in a typical pocketing application.
Dynamic milling may be all the rage right now, but in many cases high-feed ramping with an indexable milling tool can be a more efficient and flexible solution.
Check out the comparison, including both a high-feed end mill and shell mill.
This detailed instructional video (16 min 32 sec) shows you how to take advantage of plunge finishing utilizing the diameter of a tool, rather than the corner radius of a tool, to dictate the stepover needed to achieve a certain scallop height. By using plunge finishing, you can save 30% to 50% of the cycle time thanks to much larger stepovers.
Check out this simple, effective approach to finishing tapered walls and deep, straight walls.
Compare cycle time and tooling cost for three approaches to machining a 1" deep x 3.5" wide x 6" long pocket in 4140PH (28 Rc):

Dynamic/volume milling with indexable tooling rather than solid carbide end mills.
Indexable helical roughing end mills are a great alternative for dynamic/volume milling.
Constant profile ramping is a much more effective approach than conventional Z-level profiling. Watch side-by-side as a Dapra 1” end mill (50 IPM / .100" DOC) using constant ramp profile outpaces a traditional 1° helix entry and Z-level rough by more than 50%.
The new EDGE² DSS line provides premium performance, free cutter replacement and cost-per-corner savings of up to 48% to revolutionize the way your shop approaches 90° milling. This demo shows:
