Fused silica is widely used as a material for optical lenses owing to its excellent properties and low thermal expansion coefficient. However, hard brittle material, there very limited option of processing technologies machining fused with surface structures. In this paper, picosecond laser based single crystal diamond tool fabrication technology proposed generate micro milling tools different ...
An attachable electromagnetic-energy-harvester driven wireless vibration-sensing system for monitoring milling-processes and cutter-wear/breakage-conditions is demonstrated. The system includes an electromagnetic energy harvester, three single-axis Micro Electro-Mechanical Systems (MEMS) accelerometers, a wireless chip module, and corresponding circuits. The harvester consisting of magnets with...
In todays manufacturing industry, high-speed milling plays an important role. The main benefits of high-speed milling over conventional milling are the high material removal rates with relatively low cutting forces. The efficiency of high-speed milling is limited by the occurrence of regenerative chatter. Chatter is an undesired instability phenomenon, causing excessive tool vibrations, reduced...
STATEMENT OF PROBLEM Milling is a central and important aspect of computer-aided design and computer-aided manufacturing (CAD/CAM) technology. High milling accuracy reduces the time needed to adapt the workpiece and provides restorations with better longevity and esthetic appeal. The influence of different milling processes on the accuracy of milled restorations has not yet been reviewed. PUR...
In view of the unstable cutting problem in the process of high speed milling hardened steel. Conduct experiment of the stability of machine tool and high speed milling cutter. The machine tool spindle vibration spectrum and vibration acceleration signal under the condition of different centrifugal force were detected. Obtained the critical speed of security and stability cutting of milling cutt...
