Abstract In this paper, the peak heights of several turning methods were analyzed theoretically. Based on the results of theoretical analysis, a 3D-UVAT device driven by a single actuator was developed. To validate this design, the theory and experiment of 3D-UVAT have been undertaken. The FEA results show that design is safe, and can achieve obvious displacements in X-axis, Y-axis, and Z-axis. In the experiment, 304 stainless steel was chosen as experimental material. For comparison, CT, UVAT, and UEVT experiments were also carried out. The experimental results show that with the help of ultrasonic vibration, the surface grooves and defects are significantly reduced. This phenomenon is more obvious on machined surface obtained by 3D-UVAT. Three-dimensional surface topography shows that the roughness value Sa obtained by 3D-UVAT is smaller than CT and UVAT. Under some cutting conditions, the roughness value Sa of machined surface obtained by 3D-UVAT is smaller than UEVT. Thus, the results of theory and experiment proved that the 3D ultrasonic vibration-assisted turning driven by a single actuator has a great potential in improving the quality of machined surface.

Analysis of the cutting process in machining of advanced alloys, which are typically difficult-to-machine materials, is a challenge that needs to be addressed. In a machining operation, cutting forces causes severe deformations in the proximity of the cutting edge, producing high stresses, strain, strain-rates and temperatures in the workpiece that ultimately affect the quality of the machined surface. In the present work, cutting forces generated in a vibro-impact and hot vibro-impact machining process of Ti-based alloy, using an in-house Ultrasonically Assisted Turning (UAT) setup, are studied. A three-dimensional, thermo-mechanically coupled, finite element model was developed to study the thermal and mechanical processes in the cutting zone for the various machining processes. Several advantages of ultrasonically assisted turning and hot ultrasonically assisted turning are demonstrated when compared to conventional turning.

Theory And Experiment

The cutting vibration is one of the main factors to affect precision machining. In this paper, the influence of tool rake angle on cutting vibration is studied at different cutting speed in turning operation, and corresponding theoretical analysis is made. The experiment results show that: the amplitude of machining vibration gradually decreases with tool rake angle increasing; while rake angle o g <0°, the biggest amplitude occurs at V=50~70m/min; While o g ≥0°, it is at V=160~180m/min. Moreover, theory and experiment foundation is presented on avoiding the biggest amplitude range so as to guarantee quality of precision machining at high speed.

It has been one of the difficulties that high-precision small hole on stainless steel is machined. The supersonic vibration boring acoustic system is installed in the lathe. The supersonic wave energy applies to tool to create pulse power on the cutting process. The separation vibration cutting is achieved by the pulse force. The comparative tests on boring surface quality are carried. The quality of surface machined by this method is compared to that by grinding. This cutting is the green cutting. The boring process system is stability. The cutting force is greatly reduced. The cutting temperature is at room temperature. The tool life is greatly increased. Surface quality and shape precision is greatly improved. The regulations of the ultrasonic vibration boring dry cutting of stainless steel are also summarized. The test results show that the ultrasonic vibration boring by double cutter is of very superior cutting mechanism and is a high-precision thin - long deep - hole machining of stainless steel materials, efficient cutting methods.

3D Surface Topography

This research study focuses on the experimental analysis of the three-dimensional (3D) surface topography and surface roughness of the workpiece machined with ultrasonic vibration assisted turning (UAT) in comparison to conventional turning (CT). For the challenge that machining difficulties of 304 austenitic stainless steel (ASS 304) and high demands for the machined surface quality and machining precision represent, starting with cutting principle and processing technology, the ultrasonic vibration method is employed to scheme out a machining system of ultrasonic vibration assisted turning (MS-UAT). The experiments for turning the workpiece of ASS 304 are conducted with and without ultrasonic vibration using the designed MS-UAT, and then the 3D morphology evaluation parametersSaandSqare applied to characterize and analyse the machined surface. The experimental results obtained demonstrate that the process parameters in UAT of ASS 304 have obvious effect on the 3D surface topography and surface roughness of machined workpiece, and the appropriate choice of various process parameters, including ultrasonic amplitude, feed rate, depth of cut, and cutting speed, can enhance the machined surface quality efficiently to make the machining effect of UAT much better than that of CT.
