Study on the CBN Wheel Wear Mechanism of Longitudinal-Torsional Ultrasonic-Assisted Grinding Applied to TC4 Titanium Alloy

Micromachines, 2022
In this study, the CBN (cubic boron nitride) wheel wear model of TC4 titanium alloy in longitudinal-torsional ultrasonic-assisted grinding (LTUAG) was established to explore the grinding wheel wear pattern of TC4 titanium alloy in LTUAG and to improve ...

Revealing patterns in the wear of profile diamond wheels

Eastern-European Journal of Enterprise Technologies, 2020
Істотний вплив на точність обробки виробу і продуктивність процесу профільного шліфування надає електроерозійна правка круга.Для ефективного управління точністю обробки найбільш істотне значення має похибка, викликана зносом алмазного круга. Правку круга необхідно виробляти, коли знос підходить до границі, але не виходить за межі поля допуску.

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

Advanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

A Versatile‐Designable Framework for Active and Programmable Shape‐Morphing Soft Matter Systems: From Inverse Design to Closed‐Loop Control

Advanced Science, EarlyView.
A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

Fast Wear Calculation for Wheel Profile Optimization

, 2015
From the tribology point of view how a wheel material wears does not only depend on the nature of the material but also other elements of the tribo-system such as geometry of contacting pairs, surface topography, loading, lubrication and environment. The

Study on the Different Effects of Power and Trailer Wheelsets on Wheel Polygonal Wear

Shock and Vibration, 2020
The wheels of power and trailer wheelset show different polygonal characteristics since their structures are obviously different. Therefore, the frictional self-excited vibration models of wheelset-track systems are established based on the viewpoint of ...

WEAR GRINDING WHEELS WITH PRECISE WORKING SURFACE

Cutting & Tools in Technological System, 2020
. The use of circles with an intermittent working surface is an effective means of increasing productivity and reducing the heat stress of the grinding process. These positive effects are largely determined by the appearance of high-frequency oscillations in the elastic system of the machine, which facilitate the chip formation process and create ...
