Analysis of the minimum chip thickness during turning of duplex stainless steel
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2018The goal of this study has been to establish a method for quantifying the minimum chip thickness, h 1 min , during longitudinal turning of duplex stainless steel, and explore how the value of h 1 min changes with varying process parameters.

Dynamic Simulation of the Micro-Milling Process Including Minimum Chip Thickness and Size Effect
Key Engineering Materials, 2012Micro-milling with a cutting tool is a manufacturing technique that allows production of parts ranging from several millimeters to several micrometers. The technique is based on a downscaling of macroscopic milling process. Micro-milling is one of the most effective process to produce complex three-dimensional micro-parts, including sharp edges and ...

The International Journal of Advanced Manufacturing Technology, 2021
The increasing market demand for smaller products requires the development of micromachining processes. This, in turn, enhances the importance of knowledge about the phenomenon of chip formation and its characteristics at the microlevel. Conventional machining generally assumes that the tool cutting edge is perfectly sharp, and that it usually does not

Modeling the Minimum Chip Thickness in Orthogonal Micro-Cutting Based on Plastic Strain Gradient
Advanced Materials Research, 2009In micro-cutting, the uncut chip thickness is comparable or even less than the tool edge radius and as a result a chip will not be generated if the uncut chip thickness is less than a critical value, viz., the minimum chip thickness. Knowledge of the minimum chip thickness plays a key role of the selection of appropriate machining conditions and ...

IEEE International Digest on Microwave Symposium, 2002
The design and fabrication of a novel planar Schottky diode with greatly reduced shunt capacitance for millimeter- and submillimeter-wave applications is described. The dominant pad-to-pad shunt capacitance is minimized by replacing the substrate GaAs with a low-dielectric substitute.

Estimation of minimum chip thickness for multi-phase steel using acoustic emission signals
2010The determination of minimum chip thickness is important for establishing the lower limit of the feasible process window in micro mechanical machining for a given tool and workpiece material. The minimum chip thickness is encountered in micro milling operations owing to the variation in chip load as predicted by the chip density function.
