Micro milling of fused silica using picosecond laser shaped single crystal diamond tools
Frontiers in Materials, 2023 Fused silica is widely used as a material for optical lenses owing to its excellent optical properties and low thermal expansion coefficient. However, as a hard and brittle material, there is very limited option of processing technologies to machining ...

Protocol for tool wear measurement in micro-milling [PDF]
Wear, 2019 Micro-milling yields small accurate parts quickly for electromechanical, aerospace, and medical applications. Due to their small size, micro-tools wear quickly and unpredictably therefore tool wear is difficult to measure and is poorly understood, leading to excessive tool changes and reduced productivity. This paper, therefore, proposes a new protocol

Optimal tool design in micro-milling of difficult-to-machine materials
Advances in Manufacturing, 2022 AbstractThe limitations of significant tool wear and tool breakage of commercially available fluted micro-end mill tools often lead to ineffective and inefficient manufacturing, while surface quality and geometric dimensions remain unacceptably poor. This is especially true for machining of difficult-to-machine (DTM) materials, such as super alloys and

Instantaneous tool deflection model for micro milling
The International Journal of Advanced Manufacturing Technology, 2015 This paper investigates modeling of machining forces with shearing and plowing mechanisms and estimates instantaneous tool deflections in micro end milling. Cutting forces directly affect cutter deflection, which will influence the quality of machined surfaces.

Influence of tool wear on machining forces and tool deflections during micro milling [PDF]
The International Journal of Advanced Manufacturing Technology, 2015 Tool wear on the cutting edges of micro end mills is an important issue affecting process outputs such as tool deflections and surface roughness, especially when difficult-to-cut materials such as titanium alloys, stainless steel, etc. are machined at micro scale.

Machining Forces and Tool Deflections in Micro Milling
Procedia CIRP, 2013 AbstractThe analysis of cutting forces plays an important role for investigation of mechanics and dynamics of cutting process. The importance of force analysis is due to its major role in surface quality of machined parts. Presented force model calculates instantaneous chip thickness by considering trajectory of the tool tip while tool rotates and ...
