“Recommended machining parameters for copper and copper alloys” contin-ues a long tradition established by the German Copper Institute (DKI). The publication “Processing Copper and Copper Alloys” (“Das Bearbeiten von Kupfer und Kupferlegierungen”) first appeared in 1938 and again in 1940. The handbook “Metal cutting tech-

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 be inserted into the formula for the feed calculation.

Like Mickey D says, copper can be a royal pain to deal with. We used to run a lot of 1 1/4" round bar in the CNC lathe at work. Problem with copper is that it is SOOO malleable. It flows nearly as much as it cuts. You could make a threading pass and sometimes it would actually INCREASE the outer diameter, as the metal flowed around the tool.

On the mill, I've got several holes to drill for 0-80 threads that are fairly deep for that diameter (1/4" deep). Any tips? Again this is a manual machine I will be using. I'm planning to use a two-fluted carbide end mill from McMaster - are their end mills typically sharp enough for cutting copper?
