cutting speed for copper milling

The milling parameters evaluated were spindle speed, feed and depth of cut. The experiments were conducted by using L 9 (3 3) orthogonal array

Choose cutter width to slightly exceed mica thickness (recommend +.003” / .08mm). This allows saw to remove full width of mica plus .0015” (.04mm) copper on each side of slot. If unable to

Pure copper is difficult to machine on 5 axis because of its high ductility and high cold workability. Tool wear is very high and chip formation very poor. As chip compression is substantial, the cutting edge is subjected to large mechanical loads. The long tubular chips that form when pure copper is machined are difficult to handle and remove.

Simply select your machine, your material and your end mill and the STEPCRAFT Milling Calculator will show you the appropriate speed rate and cutting data in no time. n = Revolutions per minute (rpm) vc = Cutting speed (m/min) d = Tool diameter in millimeters (mm) z = Number of teeth fz = Tooth feed (mm/tooth) vf = Feed rate (mm/min) PDF DOWNLOAD

For milling, I treat it like aluminum. Uncoated, 2-3 flute, carbide mills for aluminum work great. High surface speed, and aggressive cutting: 

ChipBLASTER, of PA., creates high-pressure coolant system parts and provides the recommended high pressure milling speeds and feeds for bronze & more. 2 Flute 3 Flute 4

For cutting copper materials, you can use this copper cutting fluid. It is suitable for high-speed and low-speed operation. It has good lubricity, silky feel, reduces tool wear, good cooling performance, timely removal of heat, and improves workpiece surface accuracy and cleaning. Good, clean the debris without residue,

To physique the perspective, a survey of the pertinent literature on the turning of hardened materials is presented here. Liew et al. [] optimized the machining cutting parameters in turning of AISI D2 steel using rhombic-D-type carbide inserts with 55° included angle as a cutting tool and nanofluid as a cutting fluid.They suggested a cutting speed (C s) of 200 m/min for superior surface finish.
