Expert Machinist stores all the cutting tool data in this Tooling directory. If you want to supply cutting data for roughing and finishing with your tools, based on the stock material type and condition, you have to set up the material directory structure, by creating a subdirectory called materials in your Tooling directory, and then creating subdirectories corresponding to your stock materials and conditions in the materials directory.

Expert Machinist then places all the tool parameter files (.tpm files) in the Tooling directory, and all the cutting data for each material in the appropriate material subdirectory.
