Technology Summary

 

For machining a given material, the programmer/process engineer needs to make decisions on the tool (supplier, geometry, and grade), tool path, process parameters (cutting speed, feed rate, and depth of cut), coolant type and delivery method and fixture to hold the part.  For a given material, there are many alternatives for cutting tools and a wide range of feasible process parameters.   To illustrate, for turning nickel-based superalloys, tool supplier Sandvik has five carbide grades (S205, S05F, CG1105, CG1115, and CG1125), and four ceramic grades (CC6060, CC6165, CC6160, and CC670),  Similarly, other tooling vendors such as Kennametal, Seco, Greenleaf, and Iscar have multiple grades in carbide and ceramic materials for turning nickel-based superalloys.  For each grade, there is a wide range of feasible process parameters for a given operation.  For example, for carbide grades, the recommended cutting speed for turning Inconel 718 is between 45 m/min (150 sfm) - 76.2 m/min (250 sfm).  The recommended cutting speed for ceramic inserts is 182.88 m/min (600 sfm) - 365.76 m/min (1200 sfm).  As a result, identification of optimal tools and process parameters in machining is difficult.

This software is a web application to interactively visualize and recommend optimal process parameters in turning using the user provided test data.  The end-user is a metalworking specialist.  The web application will consist of multiple visualization components.  The visualizations will provide a way to visualize the test data efficiently to quickly identify the high-level variables, gaps, trends, and outliers in the database and select near-optimal starting process parameters and tools for a new application.
