Specifics of Reaming Allowances of Different Materials with Indexable Throw-Away Inserts

We have developed a mathematical model that takes into account walking of a reamer with indexable throw-away inserts when processing various materials. This model allows us to predict the accuracy of hole making by the tipped tool. Within the framework of the research, we plotted and calculated the material layers, which are cut by each cutting tip. We analyzed and compared the developed models of the cut layers and the mathematical model. The obtained data allow us to divide the material into two types according to its ability to be processed with a tipped tool. Shaping diagrams of cut material layers were plotted and the existed shaping diagrams of the reamer with indexable throw-away inserts were analyzed. The calculations and comparisons allowed us to conclude that the mathematical model is consistent and can be applied in production units at machine-building enterprises.
