Tool condition monitoring in micro milling of brittle materials
Precision Engineering© 2024 The AuthorsThis paper introduces a novel indirect tool condition monitoring (TCM) system for micro-milling brittle materials (glass and silicon) based on acoustic emission (AE) and cutting force signals. The milling experiments are also applied to a ductile material (steel) for comparison.

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

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.
