“…These results are in agreement with the results reported in [48], which concluded that the chip turned from a helical to snarled ribbon chip with increased cutting velocity and explained this by the reduction in chip thickness with increasing cutting speed, which prevented the formation of chip up-curl. This can also be attributed to low tool-chip interface friction and smaller chip-tool contact length at higher cutting speeds [49], which encourages a straight chip to form and prevents chip up-curl. Looking at Figure 4e,f,h,i, it is seen that the interaction of cutting speed and depth of cut has a significant effect on chip shape.…”

This article presents the results of an experimental investigation into the effect of process parameters in the precision hard turning of Ti-6Al-4V on chip morphology at both macro and micro levels. It also reports on the control of chip generation to improve chip evacuation and breakability at the macro level by varying the process parameters, namely, feed rate, cutting speed and depth of cut during turning tests. A scanning electron microscope (SEM) was used to examine the chips produced for a better understanding of chip curling mechanisms at the micro level. Surface roughness of the machined specimens was measured to assess the effect of chip evacuation on obtainable surface quality. From the results, it was found that the interaction of process parameters has a significant effect on the control of chip formation. In particular, the interaction of higher cutting speeds and greater depths of cut produced chip entanglement with the workpiece for all values of feed rates. Using relatively higher feed rates with a low depth of cut showed good results for chip breaking when machining at higher cutting speeds. Different chip curling mechanisms were identified from the SEM results. Chip side-curl formation showed different segmentation patterns with an approximately uniform chip thickness along the chip width, while chip up-curl occurred due to variations in chip thickness. Finally, it was found that the tangling of the chip with the workpiece has a significant effect on the final surface quality.

“…10 In high-speed cutting, the discontinuous chip, long curling chip, and continuous chip are produced at low cutting speed, medium cutting speed, and high cutting speed respectively. 12 In the dry drilling, the spiral cone chip is the most typical chip for Ti6Al4V alloys. During this process, with the increase of the feed rate, the chip length decreases, and cutting speed has little effect on the chip morphology.…”

There is a growing interest in developing an advanced technique to manufacture titanium alloy for larger holes in the aviation and marine industries. While the application of larger holes is limited due to the low machinability and high cost. The deep-hole trepanning is investigated to manufacture the titanium alloy in a high-efficient low-cost manner, and the technical challenges during the deep-hole trepanning process are studied in this article. Designs of the deep-hole trepanning tool and experiments under different cutting speeds and feed are carried out. Chip morphology, axial cutting force, and tool wear are analyzed. The optimal process parameters are achieved. This study provides a practical solution to process titanium alloy for potential industrial applications.

“…During highspeed cutting, the tool quality is often threatened by a high cutting temperature, and severe wear. These threats severely restrain the improvement of production efficiency, processing precision, and surface quality of products [6][7][8][9][10]. To guarantee processing quality, the traditional solution is rather conservative: tool replacement.…”

During high-speed cutting, the tool quality is threatened by a high cutting temperature, and severe wear. Traditionally, these threats are handled by tool replacement, which pushes up the economic cost of production and manufacturing. This paper explores the frictional wear detection of hard alloy tool material during high-speed cutting. Based on the theory of wave motion, the wear process of hard alloy tool material during high-speed cutting was modelled mathematically, and the wear mechanism was analyzed. To reduce the interference of weakly important features, the authors presented a method to analyze the feature importance and an approach to identify the frictional wear of tools, under the high-dimensional small dataset about the monitoring signals of tool material wear. Through experiments, the proposed algorithm was proved feasible in identifying the wear of hard alloy tool material during high-speed cutting. The research provides a theoretical guide for improving the production techniques for cutting of hard alloy material.
