Abstract Slot milling is one of the most common mechanical operations for machining composite materials. Experiments
were carried out in order to investigate the milling force and surface roughness during GFRP milling. An orthogonal
exam was designed to explore the influence of machining parameters (spindle speed, feed rate and depth of cut) on milling
force. Matlab is used to analyze the experimental data of milling force and surface roughness. After regression analysis, the
milling force and surface roughness regression equations are established. Finally, the correctness of the milling force and surface
roughness regression equations is verified by experiments. The results show that depth of cutting has a greatest influence
on milling force, while the influence of feed rate is small; spindle speed has a greatest influence on surface roughness, while
the influence of depth of cutting is small. And the error range of the milling force and surface roughness is within 20%.
