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.

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.

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,

Working with Copper: Design, Machining, and Finish Requirements. Common cutting materials are carbide application groups such as N10 and N20, and the HSS grades. You can double

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 

Cutting Speed = 75 (fpm) Diameter of Cutter = 0.38 for a 0.38 drill. One-third the speed for countersinking would be = 789/ 3 = 263 RPM. Center Drill RPM Calculations. A center drill or combination drill and countersink (Figure 6) is used for spotting holes in workpieces or for making center holes for turning work.

Some machining of copper alloys is done dry, but the use of a cutting fluid invariably increases the level of possible speed and feed, 

Copper alloys have great electrical and thermal conductivity, which make them natural choices for many electrical applications, such as bus bars and wire connectors. 101 copper offers higher conductivity due to its purity. 110 copper is generally easier to CNC machine making it more cost effective. Copper beryllium (CuBe) combines high strength

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.
