DOI: 10.1007/s12541-021-00554-6
Abstract: This paper compares UEVC (ultrasonic-elliptical-vibration-cutting) and a CC (conventional-cutting) process for micro-grooving in AISI 1045 via FEA (finite-element-analysis) in 2D orthogonal technique. The stress, cutting force, temperature, and residual stress have been examined. Average cutting… read more here.
