A Numerical Method for Determining Temperature Distributions in Machining with Coolant: Part 2: Calculation Method and Results

Abstract

A computational method is developed for determining temperature distributions in machining with coolant. Models for heat sources and equations for heat-transfer coefficients used in the calculations were presented in Part 1. In Part 2 the finite element method is applied to solve the steady two-dimensional energy equation with a coolant used on the boundaries. Using this method temperature distributions throughout the tool, work and chip in machining with coolant are calculated, given the experimental values of the cutting forces and chip thickness, the thermal properties of the work and tool materials and the heat-transfer coefficients at the boundaries. The calculated tool temperatures are compared to results measured experimentally and satisfactory agreement is shown.
