内容記述 | The frictional behavior on the relief face of a veneer cutting tool that takes part in the mechanism of veneer formation and the veneer quality becomes a serious problem of utmost importance. Few fundamental studies have dealt with this problem, and so, the main objective of this paper is to obtain information on them. In this study, the frictional stress (τ) and the normal stress (σ) over a rake face were measured in the veneer cutting without a pressure bar, using a composite tool with the restricted contact length (γ_c) between the relief face and the machined surface, as shown in Fig. 1. The results obtained are summarized as follows: (1) Two components of the cutting force are affected by γ_c, for instance, the horizontal component increases and the vertical component decreases, with increase in γ_c. (2) The distributions of τ and σ over the rake face can be expressed by Eq. (5). From the values of the coefficients and the exponents in Eq. (5), the effect of γ_c upon τ and σ is made clear (Figs. 2 and 3, and Table 1). (3) The frictional coefficient (μ) on the rake face increases with increase in γ_c, but μ can be considered to be constant under the various cutting conditions (Fig. 4 and Table 3). (4) The degree of knife checks in chip increases, but the loose side surface of the chip produced becomes relatively good, with increase in γ_c. These cutting phenomena are discussed qualitatively on the basis of the above-mentioned results. | |||||
