| Abstract Scope |
Commercially pure aluminum electrical conductor strips and wires are conventionally produced through cold rolling and wire drawing. These processes are multi-step deformation techniques that impose relatively low incremental plastic strains. This work explores an alternative technique that imposes high strains in a single-step, machining-based deformation to produce the conductor strips. However, the commercially pure aluminum alloys have high ductility in the as-cast or annealed (O-temper) condition, which gives rise to their “gummy” behavior during machining and hence, folding defects on the back face of machined strips. By varying the rake angle and cutting speeds, a process map will be demonstrated to enhance the selection of appropriate cutting conditions necessary to produce the electrical conductor strips with improved surface finish comparable to the conventional cold rolling and drawing processes. |
