Abstract
It is particularly of importance to determine temperature and heat partition on tool-chip interface in milling of difficult-to-machine materials, because they have great effect on machining process. In this paper, a new analytical method is presented to investigate temperature and heat partition on tool-chip interface in milling of difficult-to-cut materials. Besides single wire thermocouple is used to measure temperature on tool-chip interface. The tool is discretized into axial differential elements to model temperature of each differential element. The tool and chip temperature is worked out by integrating temperature of each differential element along axial direction. Secondly, Response Surface Method, an optimization method, is employed to solve heat partition on tool-chip interface. The objective function is described by matching tool and chip temperature, and the constraint condition is that heat partition cannot beyond 1. After all, the prediction temperature is compared with measurement temperature to verify this method.
