Prediction of Shearing and Ploughing Constants in Milling of Inconel 718

The present study proposes an integrated prediction model for both shearing and ploughing constants the peripheral milling of Inconel 718 by using a preidentified mean normal friction coefficient. An equation is presented identification angle oblique cutting in milling. A simplified adopted obtaining shear strain tool given helix angle, radial rake honed edge radius. predicted from analytical Merchant’s formula flow stress selected Johnson–Cook material law are shown to be consistent with experimental results. experimentally identified angles process demonstrated have approximately constant values irrespective average chip thickness. Moreover, forces obtained aged alloy good agreement force measurements reported literature. Without considering thermal–mechanical coupling effect law, work well annealed 718.
