Don't Fear High Speed Hard Metal | RobbJack Corporation

The ball end mill should be used for roughing operations and most finishing operations. Its large radius dissipates the force and heat that is generated in cutting hard material at high speeds and feeds. The ball end mill allows the user to cut closer to the net three-dimensional shape and allows for higher speeds and feeds.

Milling D2 Steel - Practical Machinist

Nov 06, 2003 · I have been trying to find the optimum cutting speed and feed for cutting D2 ANSI steel. Brinell hardness is about 250 for this high carbon, high chromium steel. I have used a 0.5 inch 5 flute mill (solid carbide TiALN coated). I set the speed at 2500 RPM and tried 3ipm. Depth of cut was 0.1" and 1/4" wide per pass.

Feeds and Speeds Charts - ShopBot

Optimizing feed rates and speeds: 1. Start off using an RPM derived for the chip load for the material being cut (see charts). 2. Increase the cutting speed (feed rate) until the quality of the part's finish starts to decrease or the part is starting to move from hold downs. Then decrease speed by 10%. 3.

Milling Speed and Feed Calculator

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
