Below are downloadable Simulation Files in DXF format (half-round line drawings) to accompany Harvey Tool products. Each file is specifically scaled to the geometry of the tool to help simulate running parameters and create tool paths. Like our speeds & feeds charts, these files will be continuously updated with the introduction of new products and new catalogs to assist operating the majority of our tools. Simulation files can also be accessed by searching for a specific tool number on the left-hand side of the website and then clicking on the Simulation table in the product table.
