Apr 15, 2014#0183;#32;So I know this topic comes up a lot but I''m still confused. My question regards cutting feeds and speeds in 6061 and 7075 aluminum. the majority of our machining is done on a Haas Mini Mill. During roughing i have an rpm of 2400 and a feerate of 11 (guessing its inches per minute). Now that gives me a chip load of

Recommended Speeds and Feeds for Side Milling Cutters Depth of cut = .050 to .250 Aluminum Alloys 2024,5050, 5056, 6061 N/A 200400 Revolution per Minute (RPM)= ( x SFM)/ Cutter Diameter Inches per Revolution (IPR) feed rate = Chip load per tooth x # of teeth
Cutting speed. Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Speeds amp; Feeds Solid Carbide High Performance End Mills. Materials Soft Grades: Speed Under 32 HRC: Materials Hard Grades: Speed Over 32 HRC: Feed (Inch/Tooth) End Mill Diameter 1/8quot; 3/16quot; 1/4quot; 3/8quot; 1/2quot; 5/8quot; 3/4quot; 1quot; Recommendation for Coated Tools: NONFERROUS MATERIALS: Aluminum + Aluminum Alloys 2024T4/T6, 2014, 6061T6/T651
This page gives cutting speeds for turning, milling, and drilling of several different materials. Turning speeds are adjusted to the feed rate of the mini lathe (/rev.), a depth of cut of, and a tool life of 180 minutes. Material: Wrought aluminum: 6061T6, 5000, 6000, and 7000 series. 500 600: 2820:
To calculate feed rate select a specific RPM from the range below. 1070 1681 RPM 2292. Recommended RPM range is 1070 2292 RPM. At the speed of 1681 RPM, the recommended feed rate is
I have found that milling aluminum at speeds and feeds you would expect to use on a soft alloy steel on an industrial machine will produce effortless results. Speeds and Feeds for Drilling Although I suggested only using carbide for your endmills, high speed steel (HSS) drill bits will work perfectly fine.
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.
Milling Speeds and Feeds Charts The most important aspect of milling with carbide end mills is to run the tool at the proper rpm and feed rate. We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
