Study on Nano Grooving Process for Optical Quartz Glass by Molecular Dynamics Simulation Method

YC Lin and CY Wu, 2019 IEEE 6TH INTERNATIONAL CONFERENCE ON INDUSTRIAL ENGINEERING AND APPLICATIONS (ICIEA), 86-90 (2019).

Optical quartz glass has been widely used in consumer electronics. This work investigated the nano grooving of optical quartz glass using a molecular dynamics simulation (MD) method. Moreover, the critical depth of grooving with tool tips of different radius was discussed. The cutting force and the amount of elastic recovery of the grooved depth were evaluated under different cutting conditions. The simulation results showed that the critical depth of grooving and the amount of elastic recovery of the grooved depth were dependent on the radius of the tool tip. A cutting tool with a smaller radius can obtain a smaller critical depth of the groove.
