Keep the feed rate between 5 and 8 thou/rev The speed should be 300 to 600 rpm. Pick which very gives you the finish your looking for, you can 

I am trying to figure out what is a good feed to start with for milling copper. I am using a 1/8" 4 flute endmill (HSS-no coating)

Finishing – 0.010 inch to 0.015 inch cutting depth and 0.004 inch to 0.010 inch feed at 250 to 400 SFM. Tapping It is recommended to use high-speed steel or 

Copper, titanium and stainless steel are difficult due to stringy chips. A combination of higher feed rates and lower speeds should also

10/30 · Incorrect speeds and feeds will cause more rub and less cutting, resulting in more heat generation passed to the workpiece. In these situations, machining can become next to impossible, and serious tool wear and eventual tool breakage are inevitable if the tool continues to be fed the same way. How To Avoid Work Hardening

The recommended speeds and feeds presented in this report for high speed steel tools are based on single point tool lives of sixty minutes of continuous cutting, resulting in a 0.060 inch wear

The feed speed is the speed at which the cutting tool engages the workpiece. Therefore, you must set the correct feed speed before processing the copper parts, because it will affect the quality, life and surface finish of the copper parts. In addition, copper conducts heat rapidly. Therefore, high feed rates increase tool wear over time.

Milling Speed and Feed Calculator. Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. 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

Feeds and speeds are important, because they're the key to Longer Tool Life, Faster Machining Speeds (through higher Material Removal Rates), and Better Surface Finish. But they involve a lot of different concepts, which can make them hard to learn.

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 per revolution (IPR) were achieved for practical production periods (>4 hours) on all alloys utilizing a coated carbide insert. The chart below illustrates that the same amount of

The recommended speeds and feeds presented in this report for high speed steel tools are based on single point tool lives of sixty minutes of continuous cutting, resulting in a 0.060 inch wear land. The recom - mended speeds and feeds for carbide tools reflect thirty minutes of contin- uous cutting with a resulting 0.015 inch wear land.

Hi all, We are starting to work with some beryllium copper in our shop, and are pretty inexperienced with machining of this material.

Feed rate describes the rate at which the CNC cutting tool is fed (or advanced) against the workpiece. We recommend low to moderate feed rates 

Because of the wide variation in machining characteristics among the various coppers and copper alloys, tool design, as well as speed and feed, must be varied
