メラミンパーティクルボードの被削性(第2報)

The experimental matrix from previous work [5] was expanded by a high temperature corrosion effect (HTC) of particleboard towards a binder in cemented carbide, expressed by quantifier ( R_<MSMI>) ' A new multivariable analysis was developed, incorporating a complete model of cutting edge wear (h^P) from a cutting path (C_p), sharpness (β_F) and rake (γ_F) angles, content (S_<AC>) , weighted average size of particles ( W_<ASS>) of mineral contamination, a quantifier (R_<MSMI>) and a porosity fraction (P_s). A model of the functional dependence h^P=f(C_p, C_s, β_F, y_F, R_<MSMI>, S_<AC>, W_<ASS>, P_s) during coated particle board longitudinal milling was developed. The HTC effect was confirmed as an important factor influencing the tool wear process dunng particleboard milling. This material property has not been considered in previous studies [4, 5].
