Abstract

Based on the 3-D analytical model of chip curling developed in the part I of this paper [1], a systematically theoretical analysis and further discuss have been done in this part by differentiating the model with respect to three chip angular velocity components ωx, ωy, ωz and chip flow angle η0 for the effects of the three chip angular velocity components. Based on the analysis, a group of criterions for the effects of ωx, ωy, ωz and η0 on the chip forms/shapes is obtained, and the varying tendency of the chip radius and chip pitch with varying ωx, ωy, ωz and η0 is discussed based on the group of criterions. Further, for better understanding, a group of 3-D diagrams has been given in order to visualise the varying tendency of the chip forms/shapes with the three chip angular velocity components and chip flow angle. The results of the analysis and discussion reveal that the chip twisting is an effective approach to chip breaking, specially for the thin chip breaking. These are significant in theory to direct the geometric design of the chip breaker/groove and effective control of chip breaking process.
