attributes to the transformation of fracture mode from intergranular fracture for A to intergranular fracture for B composites
The tool life of the A and B composite tools was 5 times and 7 times longer than those of comercial tools in machining gray cast iron
finding
Nearly
the optimum cutting parameters for minimum cutting forces, surface roughness and better tool life.
surface roughnees are found well below the tool rejection criteria
abrasion
due to diffusion, thermal softening and notching at higher cutting speeds
The result clearly shows that feed rate was the most powerful factor on the surface roughness for all tools
near dry machining
