 This paper investigates the effects of machining parameters on the machinability of flax poly, lactic acid, biocomposites through drilling experiments using a low-cost measurement setup and an over-analysis to identify significant cutting parameters. The results show that spindle speed reduces thrust force and delamination size, while feed and drill diameter increase both thrust force and delamination factor. Feed rate plays a key role on delamination damage area, and the best hole quality is achieved with specific spindle speed and feed rate values.
