A Study of Chip Flow for Effective Chip Control in Turning Operations

摘要

Chip control is becoming increasingly important in modern automated machining and greatly affects the efficiency and workpiece surface quality in component manufacturing. One crucial factor for effective chip control is the direction of chip side flow over the cutting tool rake face. In this paper, a model is presented which predicts the chip flow direction in turning operations with nose radiused tools under oblique cutting conditions. Experimental studies have verified the proposed chip flow model and shown that the model predictions are in excellent agreement with the experimental results.
