How to determine the optimal mesh size for a model with more than two parts?

Could someone tell me how to determine the optimal mesh size for a model with more than two parts?
When I making a mesh sensitivity analysis for a drilling simulation (two parts)，I kept constant mesh size for the bit model, and change the mesh size of the rock model. When the results (contact force) reached convergence, I regard it as an optimal mesh size for this simulation.
However, for a model with more than three parts, how to handle it?
