Oct 19, 2017 · If I was in a mold shop and all I ever had to machine was P20 and H13 with the same dozen or so cutters, I could make one hell of a good database. The tools are sometimes long or very small in diameter, but the setups are usually rock solid. Now the flip side is the job shop. Material could be D2 tool steel or 356 cast aluminum.
SFM = Surface Feet per Minute. AS THE DOC DECREASES THE FEED RATE CAN INCREASE. SCT CBN inserts are excellent for continuous cutting of a wide range of hardened steels, powdered metals, cast irons and super alloys. The inserts are precision ground with hones for machining to sub-micron finishes with maximum tool life. CNC Speeds and Feeds Easy Speeds And FeedsHigh Speed Steel Drills (HSS) Click for Metric.

Apr 01, 2008 · This smaller tool, a finishing tool, used a radial depth of cut of 0.0039 inch. The die cast die (bottom) was machined from 60-HRC material using tools ranging from a 3-mm ballnose tool run at 19,000 rpm and 133 ipm, to a 0.2-mm ballnose tool run at 40,000 rpm and 16 ipm. This small tool took a 0.000118-inch radial depth of cut. High-Speed Milling Guidelines for Hardened Tool Steels Mar 01, 2000 · Do not rely on old conventional milling parameters with which you may be familiar. High speeds for milling of tool steels range from about 1,500 to 3,000 sfm. Always consider the actual "sharpness" of your tool. Typical tool edge radius (sharpness) varies between 0.0002" and 0.0004"; therefore, realistic chip loads should be a minimum of 0.0010".

Hot Work Tool Steel H11, H13 Tool Steel Suppliers in H13 is a 5% chromium hot work tool steel designed for Application that require extreme toughness combined with good red-hardness. H13 allows an extra margin of safety in tools subject to heavy hammer blows, and those containing deep recesses or sharp corners.

Now choose the right surface feet per minute (SFM) or surface meters per minute (SMM) Use the SFM and the diameter of the mill to calculate the RPM of your machine. Use the RPM, IPT, CLF and the number of flutes to calculate the feed rate or IPM.
