Analysis of effect of complicated groove inserts on chip section profile

3-D complicated groove is perfected than those past grooves.

By using a coutact gone method the chip breaking mechanism of UG chip breakers of carbide turning insert has been experimentally studied in this paper.

Aiming at the problem of groove optimization of milling insert with 3D complex groove, the experiments about milling force and milling temperature and the finite element analysis have been done.

Based on the study of the influence of insert’s groove configuration on chip-restricting, the predicting models for chip-restricting and chip-breaking are established, the method of forecasting chip-curling and chip-breaking is brought forward, and the experiments of chip-restricting and chip-breaking for turning inserts with three-dimensional complex groove are fulfilled.

Aiming at the structural characteristic of complex groove, by studying the chip restriction action of geometrical element which is composed of complex groove, the equation of chip restriction action point and the prediction formula of chip - curl directional angle are deduced and the prediction model of complex groove chip up -curl radius and side -curl radius are destablished.

Effects of geometrical parameters of chip-breaker on the carbide cutte r in chip-breaking process are expounded, and the chip-breaking mechanism is a na lyzed.
