document: Modeling cutting temperatures for turning inserts with various tool geometries and materials Temperatures are of interest in machining because cutting tools often fail by thermal softening or temperature-activated wear . Many models for cutting temperatures have been developed , but these models consider only simple tool geometries such as a rectangular slab with a sharp corner . This report describes a finite element study of tool temperatures in cutting that accounts for tool nose radius and included angle effects . A temperature correction factor model that can be used in the design and selection of inserts is developed to account for these effects . A parametric mesh generator is used to generate the finite element models of tool and inserts of varying geometries . The steady-state temperature response is calculated using NASTRAN solver . Several finite element analysis -LRB- FEA -RRB- runs are performed to quantify the effects of inserts included angle , nose radius , and materials for the insert and the tool holder on the cutting temperature at the insert rake face . The FEA results are then utilized to develop a temperature correction factor model that accounts for these effects . The temperature correction factor model is integrated with an analytical temperature model for rectangular inserts to predict cutting temperatures for contour turning with inserts of various shapes and nose radii . Finally , experimental measurements of cutting temperature using the tool-work thermocouple technique are performed and compared with the predictions of the new temperature model . The comparisons show good agreement
