High Frequency Vibration

Both rotary ultrasonic machining (RUM) and conventional grinding (CG) experiments were performed on the glass BK7 specimen to investigate the effects of high frequency vibration on the surface quality. The surface morphologies produced in the two machining processes were assessed and the associated material removal mechanisms were explored. Also, the influence of the spindle speed on the surface roughness was discussed. It was found that the mechanisms of the material removal involved in the RUM process were material pulverization and brittle fracture, while ductile flow and brittle fracture prevailed on the material removal in CG process. The increased spindle speed would reduce the lateral cutting depth of each abrasive, and promote the shielding effects of the lateral cracks generated by the previous abrasive, leading to the reduction of the surface roughness in both RUM and CG processes.

Practical Implications

As one of the cost-effective machining methods for advanced ceramics, rotary ultrasonic machining (RUM) has attracted much attention and there exist numerous publications on the process. However, few investigations on tool wear in the RUM process have been reported. This paper, for the first time in literature, presents an experimental observation on tool wear in RUM of alumina. it presents and discusses the results on tool wear in RUM of alumina. It also discusses some practical implications of the findings from this study.

Failure Monitoring

Tool wear and failure monitoring has raised quite a lot of interests among researchers and has consequently been studied in a number of research projects by a number of research organisations. However, few researchers monitored tool wear in rotary ultrasonic machining (RUM) using various sensors. This paper, for the first time in literature, presents an experimental monitoring on tool wear in RUM of silicon carbide (SiC) using accelerometer, force and acoustic emission sensors. A digital microscope was used to observe the actual tool wear during the experiment. After describing the experimental procedures, it presents and discusses the results on tool wear and acceleration signal, force signal and acoustic signal in RUM of SiC

This article presents the use of the rotary ultrasonic machining process for drilling holes in Ti6Al4V alloy which is regarded as a difficult-to-cut material due to its high-temperature strength and low thermal conductivity. This research presents an experimental investigation on the effect of the key rotary ultrasonic machining input parameters including ultrasonic power, spindle speed, feed rate, and the tool diameter on the main output responses including cutting force, hole cylindricity and overcut errors, and tool wear. No previous reports were found in literature to experimentally investigate the effect of the rotary ultrasonic machining parameters and the tool diameter on tool wear, surface integrity, and the accuracy of the drilled holes in Ti6Al4V alloy. The results showed that the rotary ultrasonic machining input parameters within the current ranges can significantly affect the quality of the drilled holes. Through proper selection of input parameters, holes could be drilled in Ti6Al4V alloy with smoothed surface morphology, low tool wear (0.7 mg) and very low cylindricity (2 µm) and overcut (120 µm) errors. Moreover, it was found that the selected level of any input parameter has the ability to significantly affect the influence of the other input parameters on the output responses.

Due to their unique properties, titanium alloys are attractive for some unique applications especially in the aerospace industry. However, it is very difficult to machine these materials cost-effectively. Although many conventional and non-conventional machining methods have been reported for machining them, no reports can be found in the literature on rotary ultrasonic machining of titanium alloys. This paper presents an experimental study on rotary ultrasonic machining of a titanium alloy. The tool wear, cutting force, and surface roughness when rotary ultrasonic machining of the titanium alloy have been investigated using different tool designs and machining conditions. The results are compared with those when machining the same material with diamond grinding.
