Composite manufacturing with multiple energy fields is an important source of processing technology innovation. In this work, comparative experiments on the conventional grinding (CG) and ultrasonic vibration-assisted grinding (UVAG) of hardened GCr15 steel were conducted with WA wheel. The grinding wheel wear patterns and chips were characterized....

... surface quality signicantly affects the performance of the parts and the reliability of the machine. Meanwhile, the R a value is reduced by up to 18.96% in UVAG. Figs. 8b and 8c show the ground surface proles obtained using the two types of grinding strategies in the case of Q' w = 2 mm 3 /(mm·s). The peakto-peak values for the height of grooves on the ground surface in CG and UVAG are from −1.440 and −1.146 µm to 1.504 and 1.204 µm, respectively. The R a value is related to the height of the residual area of ...

Optical frequency combs have received increasing attention, thanks to their fundamental importance in optical computing, communication, sensing and metrology. Recently, thermal phonon counterparts of frequency combs have shown ~10² comb teeth and ~10³ teeth spacing, and limited to the high-frequency range over 100 kHz. In contrast, we report the fi...
The surface strengthening treatment of 8620H carburized steel was carried out by ultrasonic surface rolling (USR) process, and the samples with and without the treatment were subjected to friction and wear experiments at 25°C, 100°C, and 150°C. The experimental results showed that the samples with USR treatment had higher surface hardness, lower su...
The results of the research on road surface cleaning in the winter period are presented. Among the most time-consuming are works to ensure the passability and safety of road traffic in the winter period. They account for a significant part of road maintenance labor costs. At the current stage of the development of equipment designed for the destruc...
The paper aims to represent a monocular vision autonomous car prototype using the Raspberry-Pi as a processing chip. The pi-camera module along with an ultrasonic sensor is used to provide necessary data from the real world to the car which would then pass the data on to the raspberry-pi. The car is capable of reaching the given destination safely...
