Effect of Milling Parameters on Amplitude Spectrum of Vibrations during Milling Materials Based on Wood

Milling with use of CNC machines is a well-established method and much research was concluded on this topic. However, when it comes to wood composites, the material non-homogeneity brings lot variability into cutting conditions. As part potential signals for nesting milling, vibrations at clamping points were examined in study. The main goal conclude if parameters have statistically significant effect measurement. place measurement analyzed so accessible machine operator. Medium density fiberboard particleboard specimens cut through by razor spiral mill, spindle rotating 10,000 20,000 min−1 feed rates 2, 6, 10 m·min−1. Vibrations measured vacuum grippers, then processed fast Fourier transform. Then, frequency spectrum maxima compared, as well amplitude sizes. Main frequencies roughly 166 Hz multiples, suggesting their origin tool rotation. When use, rotation, rate seemed affect result. Frequency amplitudes subjected analysis variance, found speed, tool, specimen material. No differing rates.
