| Abstract Scope |
Commercially pure aluminum sheets and strips are conventionally produced through cold rolling. This process is a multi-step deformation technique that imposes relatively low incremental plastic strains on the strips. This work explores an alternative technique that imposes high strains in a single-step, machining-based deformation to produce the sheets and strips. However, the commercially pure aluminum alloys have high ductility in the as-cast or annealed (O-temper) condition, and often exhibit “gummy” behavior during machining. The ductile flow mode of these alloys renders the production of extremely thicker strips with uneven free surfaces. 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 strips with improved surface finish comparable to the conventional cold rolling processes. The microstructure and texture are also shown to be distinctly different from strips produced by conventional cold rolling. |
