“…Single-point diamond fly cutting technology [40,41] is used to process infrared optical materials, such as KDP crystals; the machining contour is controlled by single-crystal and natural diamond tools, and the surface roughness is ensured using CNC schemes. As only a surface layer of the material is removed by diamond fly cutting, the surface damage can be reduced, resulting in improved surface quality.…”

The application range of potassium dihydrogen phosphate (KDP) crystals can be expanded by enhancing their surface quality properties. Therefore, a method for controlling the surface-temperature field of various materials was developed to expand the plastic zone to overcome the difficulty in processing KDP crystals. The ductile/brittle transition depth of the KDP crystals was determined using a 38 nm nanoindentation experiment. The nanoscratch experiment revealed the rules of how the transformation depth of the KDP crystals changes with temperatures, and the effect of temperature on the microstructure of the KDP crystals was studied. Finally, KDP crystal surfaces were processed using a UPDFC machine at elevated temperatures. According to our experiments, the surface roughness of the KDP crystal reached 5.275 nm as temperature increased, thus enhancing its surface quality. This method could be applied to other brittle materials.

“…The mill cutter is assumed to be oscillated with an angle of Δθ which effects the roundness and surface roughness. Angle of mill cutter shift and effective radius of the hole with respect to machining time are estimated using equations ( 6) and ( 8), respectively (Zeqin et al, 2018).…”

“…They concluded that the cutting speed affected the surface roughness as well as circularity during the helical milling. Zeqin et al (2018) stated that amplitude of cutter vibration is an important parameter that causes errors in circularity and cylindricity. They studied effect of vibration on tool locus and surface quality in single-point diamond turning.…”

Relative vibration between the cutter and workpiece has an influence on the surface generation and dimensional accuracy. In the present work, prediction models were developed for roundness and surface roughness of hole in terms of amplitude and frequency of tool vibration. The proposed methodology carried out a theoretical investigation on the effect of tool vibration components in X- and Y-directions on the mill cutter end point to estimate hole roundness and surface roughness. Series of helical milling experiments were conducted at different levels of spindle rotational speed, cutter orbital speed, and axial depth of cuts using 10- mm and 8- mm diameter mill cutters on Inconel 718. Predicted values of the roundness and surface roughness of hole were compared with predicted values and verified accuracy of the proposed prediction models. The experimental results indicate a good agreement with the predicted value. At spindle rotational speed of 2000 r/min and cutter orbital speed of 50 r/min, the measured and predicted values of the roundness were found to be almost same as the required roundness. The surface roughness was found to be very less at 50 r/min of cutter orbital speed.

“…The results show that the tool cutting speed has the highest influence on tool wear. Zeqin et al [19] proposed surface roughness model considering the influences of toolwork vibration components in feeding, cutting and in feed cutting directions as inputs. The developed model with three direction vibrations makes a better prediction for the single diamond turned surface.…”

In machining of high hardness steel, vibration of cutting tool increases tool wear which reduces its life. Tool wear is catastrophic in nature and hence investigation of its assessment is important. This study investigates experimentally induced vibration during turning of hardened AISI52100 steel of hardness 54±2 HRC using coated carbide insert. In this context, cutting tool acceleration is measured and used to develop a novel mathematical model based on acquired real time acceleration signals of cutting tool. The obtained model is validated as R2= 0.93 while its residuals values closely follow the straight line. The predictions are confirmed by conducting conformity test which revealed a close degree of agreement with respect to the experimental values. The Artificial Neural Network (ANN) examination is performed to determine the model regression value. The study shows that the examined reports forecasts of ANN are more exact than regression analysis. The future directon of this investigation is towards developing a low-cost microcontroller-based hardware unit for in-process tool wear monitoring which could be beneficial for small scale industries.
