Use sharp carbide mills, replace them often, and keep the flute count down, i.e. 2 instead of 4, and get the rpm as high as your machine can allow. Use a fairly 

The study focused on copper alloys 6Al-4V, the most common being α + β alloy. In conclusion, the two models developed in this study are able to predict the tool life based on the cutting speed and radial width of cuts. As long as certain parameters are met, the models will ensure the highest possible metal removal rate.

2003/3/23 · Hi all, We are starting to work with some beryllium copper in our shop, and are pretty inexperienced with machining of this material. If somebody with experience could suggest speeds and feeds for drilling and tapping, with both carbide and high speed drills, I would be very grateful. Thanks in a

Calculate the Speeds and Feeds of Carbide End Mills, Diamond End Mills, and Plastic Cutting Carbide End Mills with these General Machining Guidelines.

a Makino V55 3-axis Vertical Machining Center with 20K RPM spindle capacity. The principal data collected were power factor values (horsepower/metal removal rate), tool wear and chip formation. Maximum Speeds and Feeds Achieved. For single point turning, cutting speeds up to 4,000 surface feet per minute (SFPM), and feed rates up to 0.015 inches

To generate suitable cutting conditions with such small tools, extremely high rotational speeds of the spindle are required. Here it is chosen to be 200.000 rpm

Trace-A-Matic specializes in CNC milling of copper parts and assemblies using state-of-the-art CNC mills, 5-axis machining centers, and high-speed cutting 

For roughing,, try 0.050″ to 0.200″ depth of cut. For finishing, try 0.010″ to 0.030″ depth of cut. Use sharp positive rake tooling and avoid dull tools. End Milling Tungsten Climb milling recommended where possible as are solid carbide tools. End milling is similar to grey cast iron, but be a little more conservative.

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm. 19904 rpm = ( 500 *1000) / (3.14 * 8) If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to
