Calculated Parameters of Chip Formation for Restricted Oblique Cutting of Plastic Materials

This study of chip formation process when cutting plastic materials supplements the earlier works of a number of well-known authors in this subject area. The relevance of the research is related to the problem of determining calculated parameters of the chip formation process that excludes extensive experiments. Using combined cutters equipped with hard-alloy replaceable indexable plates as an example, the author applies ways and methods of the theoretical analysis of geometrical parameters of the tools and chip formation zone for restricted oblique cutting of plastic materials. The established quantitative connection between tool geometry, physical and mechanical characteristics of the tool and processing materials, direction of the chip flow and characteristics of the chip contact, shear angle and contact pressure is a distinctive feature of the study. The obtained quantitative results are represented in the form of an integrated algorithm that serves as a basis for calculating key parameters of processing plastic materials by cutting.
