To　monitor　the　changes　in　cutting　force　during　the　machining　process　of　machine　tools,　this　article　takes　ZL205A　aluminum　alloy　as　the　research　object　and　builds　a　multi-sensor　acquisition　system,　including　cutting　force　signal,　load　current　signal,　and　vibration　signal　acquisition　system.　Cutting　experiments　were　conducted　to　obtain　cutting　force,　load　current,　and　vibration　amplitude　under　different　process　parameters.　The　time-frequency　characteristics　of　cutting　force　signals　were　analyzed.　The　mapping　relationship　between　cutting　process　parameters　and　cutting　force,　as　well　as　load　current　and　cutting　force,　was　established.　This　research　enables　indirect　monitoring　of　dynamic　cutting　force　signals　by　monitoring　load　current　signals,　providing　reference　and　guidance　for　monitoring　dynamic　cutting　force　in　actual　machining　processes　and　process　optimization.　©　2024　SPIE.
