摘要：
In this paper, primary and secondary deformation zone of chips produced by vibration turning (VT) and ordinary turning (OT) are investigated and compared with each other to study seizure length and shear angle. To do this, it is required to quickly stop moving chips on the surface of vibrating tools. A fixture with the ability to quickly stop vibrating tool was designed and manufactured. Workpieces were tubular and made of AISI304, and cutting tools were DCMW11T308. Orthogonal cutting tests were performed by VT and the process was stopped quickly while chip moving on tool surface; then, shear angle and seizure length were measured by an optical microscope. Based on the achieved results, applying ultrasonic vibrations to turning process can increase shear angle and decrease seizure length.
