Abstract

During face milling machining, several machining parameters such as feed rate and cutting
speed determine the surface quality of the workpiece produced by the process. The selection of the right
parameters will lead to the surface quality as planned. Therefore, to improve machining effectiveness, a
method is needed to determine the appropriate machining parameters to produce the desired surface
quality. This research was conducted using a milling machine, five variations of cutting speed and five
variations of feed rate were used to cut the workpiece aluminum alloy 7075. After machining, the surface
roughness was measured using a surface test. The surface roughness value is then substituted into the
feed rate equation and effective cutting speed. By finding effective cutting parameters, the machining
process will be more efficient and effective without using unnecessary resources. From the results of the
study note that the development equation to determine the feed rate based on the value of surface
roughness is ???? = 0,6????
????? ????????
0.443mm/tooth. Development equation to determine the effective cutting speed
based on Surface roughness value is ???????? = 3.0686
????????
0.124 mm/min
