Using a Button Cutter to High Feed Ramp a Mold Core, then Plunge Finishing for Shortest Cycle Time

Mold core roughing can be very effectively done using high-feed ramping, even with a button cutter! Dapra's DTB-series double-sided button cutters are robust, 12-index tools that allow aggressive metal removal, without the dependence on exact depth of cut like high feed cutters require. In this video, Dapra shows a real-world example of how to use the high-feed ramping technique with this style cutter.

Mold core finishing can be done with various different cutter styles. One of the most efficient ways is to use a smaller-radius bull-nose style tool, but in a plunge finishing approach vs traditional profiling. Ball nose and barrel-style cutters can take a large step down, but also create more tool pressure due the increase in surface-area contact, potentially costing size and time due to the need for subsequent additional finish passes. Using a bull-nose style tool minimizes tool pressure, and using plunge finishing causes the CAM software to calculate stepover by cutter diameter, minimizing cycle time.
