Abstract:
Machining proses or metal cutting process is a main activity practised by small and medium metal enterprise by using conventional machines. This machining process is directed to produce the mass products (low variation and high repetition), such as components of machine or another equipments, but often also the macining process is made inappropriately, or even in total false methode, such as false selection of tool, thus the worn-out fastly, over cutting speed, thus surface is rougher, and etc. In this paper, the machinability on cast iron cutting is assessed (the material usually worked in small and medium metal industries), i.e., by making some experiment to obtain the most optimal cutting condition (v, f ,and a) to have the short cutting time, big cutting volume, lower surface roghness and longer tool life
