Metallurgical Engineers want an estimate of the temperature along the cutting edge of a lathe cutting bit for strength considerations. They have come to you for help. Based on the information they can provide, you decide to create a thermal conduction model of the cutting bit using the 2-D, finite-difference method. The sketch of the bit is shown below. It includes the bit geometry, boundary conditions that are known or are to be assumed and your finite-difference nodal network (mesh or discretization) of the geometry. As a start to the modeling, develop the 2-D, finite-difference, energy balance equations for Nodes 4 and 6.
