Comparison of Machining Simulations for 1045 Steel to Experimental Measurements
Robert W. Ivester, Michael Kennedy
This paper compares model-based simulations to experimental measurements obtained under the Assessment of Machining Models project at the National Institute of Standards and Technology. Validation of models and simulations under this project rely on measurements from carefully conducted benchmark machining tests performed under a broad range of machining conditions using American Iron and Steel Institute (AISI) 1045 steel. This paper focuses on comparing finite-element model simulations to the benchmark test data and discussion of limitations of experimental measurements and simulations in capturing process behavior. Cutting forces, temperatures, and chip dimensions predicted through simulation are compared to measurements of these variables from the Assessment of Machining Models benchmark test data.
