Abstract
Spectral analysis is used to investigate the cutting force parameter. The cutting forces are analyzed at each frequency under a set of frequency content. Fast Fourier Transform (FFT) technique is applied to transform from the original form into cutting force data in frequency domain. The result shows the cutting force is directly proportional to the depth of cut and inversely proportional to the spindle speed of the end mill machine. The cutting force data will later be used as an input disturbance for XY table ball screw drive system during the simulation process in the MATLAB Simulink diagram.
