Abstract: SiC particle reinforced Aluminum posite (. SiCp/Al) is a kind of
hard-to-machining materials with excellent mechanical and physical properties and wide
application perspectives. On machining it is focused. To meet the need on machining SiCp/Al
20 surface with large material to remove and high accuracy, influence of machining parameters and
mill-grinding tool on SiCp/Al machining forces was experimentally investigated taking
mill-grinding narrow slot as a typical example. Based on the results of analyzed experimental data,
rules to select the optimum machining parameters and mill-grinding tool were concluded for the
objective of low machining force.
