Abstract GLARE laminates are multi-layered metal-composite materials created from bonding sheets of metallic alloys with carbon or glass fibre layers. The application hybrid-conventional machining processes such as ultrasonic-assisted drilling (UAD) is becoming great interest to the aerospace industry due its capability in reducing cutting forces and tool wear which directly responsible for dri...

Carbon fiber–reinforced polymer (CFRP) and titanium alloy stacks play a significant role in the aerospace field to improve mechanical properties of assembly components. Low-frequency vibration-assisted drilling (LFVAD) can realize periodic contact separation characteristic between tool workpiece, thus pose high potential for manipulating machinability CFRP/Ti stacks. In present study, two types...

Minimum Quantity Lubrication (MQL) is a cooling and lubrication variant applied, for instance, in drilling processes. In the present approach, new vibration-assisted process analyzed, which has considerable potential manufacturing of extremely hard materials. Within this process, MQL gas/liquid transport presence vibrating rotating twist drill bit borehole to be studied. Multiphase computationa...

a new dynamic friction model for modeling of elliptical vibration assisted turning (evat) was developed in this research. the periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. in modeling of machining processes (including the evat process), static coulomb friction model was employed by most of the researchers. because of the peri...

High-speed circuit boards are created to meet the high-speed signal transmission requirements of 5G communication technology, but non-polar resins, flat glass fibers, and multiple hard fillers used for this purpose have posed new challenges their micro-hole processing. The quality has always been a decisive factor in board performance. Therefore, paper aims at proposing processing method improv...

The biomass extrusion process for making biomass briquettes or logs normally requires large amounts of energy to overcome the springback of the material and friction with the die surface. Also, the products readily expand and disintegrate because of the retention of internal stresses. In this study, tests on vibration-assisted compaction of biomass were performed as a method to reduce the energ...
