“…Increasing the quality of hardened surfaces can be carried out by abrasive processing [27][28][29] or nishing machining [30,31]. In this study, laser borided surfaces were machined on the lathe, however, due to the fact that hardness of nickel borides is approximately 1000 HV [32], they can be considered as a hard-to-cut material.…”

This study concentrates on comparing effects of conventional and laser-assisted machining (LAM) of laser borided Monel 400 alloy. For this purpose, the shaft made from Monel 400 was covered with 200 µm thick boron layer and surface melted using diode laser. For determining the in uence of laser beam scanning velocity on nal microstructure, microhardness and depth of melting, four laser beam scanning velocities were set: 5, 6, 8 and 10 m/min. Obtained microstructures are typical for laser melted metal and are composed of ne crystals. Microhardness increased signi cantly due to enriching Monel 400 with boron and the level of this increase depends on laser beam scanning velocity carried out for the process. During both conventional and laser-assisted turning cutting forces were measured for comparison. Other compared parameters after carrying out these processes were: obtained surface roughness and tool's life. It was found that it is possible to form laser borided surface of Monel 400 alloy by machining and using additional laser-assist has a positive impact on the e ciency of the process. The paper is the rst description of effects obtained by laser assisted machining of laser borided surface.

“…In addition, grinding wheels must be applicable to both traditional finishing applications and high-performance grinding. (1)(2)(3)(4) The rapid development of grinding tools has also led to the development and application of high-performance grinding machines and superhard abrasive grinding wheels. (5) However, the edges and corners of grinding wheels are gradually rounded during grinding, which reduces the self-sharpening ability of grinding wheels.…”

In this study, an accelerometer was installed on a computer numerical control (CNC) grinding machine, and the vibration signal of the accelerometer was processed by short-time Fourier transform (STFT) to observe the correlation between the wear behavior of the grinding wheel and the characteristic frequency during the grinding process. Two sets of accelerometers were adopted to collect the vibration signal, which was transformed to a time-frequency diagram by STFT. From the time-frequency diagram, it was deduced that the frequency bands of the grinding wheel and the workpiece were 500-700 Hz and 1200-1280 Hz, respectively. According to the comparison between the frequency band and the time-frequency diagram of the sensing signal at the workpiece with surface roughnesses R a and R Z , when the spectral energy increased, the surface roughness of the workpiece increased significantly, the self-sharpening was completed at the same time, and the increased surface roughness of the workpiece was maintained.
