Model-Based Analysis of the Surface Generation in Microendmilling—Part II: Experimental Validation and Analysis

The surface-generation models for the microendmilling process developed in Part I (Liu, DeVor, and Kapoor, 2007, J. Manuf. Sci. Eng., 129(3), pp. 453–460) are experimentally calibrated and validated. Partial immersion peripheral downmilling and full-immersion slotting tests are performed over a wide range of feed rates (0.25–12μm∕flute) using two tools with different edge radii (3μm and 2μm) and runout levels (2μm and 3μm) for the investigation...
