Determination of Minimum Uncut Chip Thickness in Micromachining

Advanced Materials Research, 2009
In micromachining, the uncut chip thickness is comparable to the tool edge radius, and chip won’t be generated if the uncut chip thickness is less than a critical value, besides that, the minimum uncut chip thickness affect many factors such as the cutting force, the chip’s modality, the cutting surface quality, etc. In this paper, a geometric model is

Minimum chip thickness determination by means of cutting force signal in micro endmilling

Precision Engineering, 2018
Abstract Issues related to ploughing affecting the performance of the micromilling process have recently been reported in literature. It is well known that there is a minimum chip thickness (hmin) below which ploughing is the main material removal mechanism and no shear occurs.

An Analytical Model for the Prediction of Minimum Chip Thickness in Micromachining

Journal of Manufacturing Science and Engineering, 2005
In micromachining, 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. The minimum chip thickness effect significantly affects machining process performance in terms of cutting forces, tool ...

A Micro Milling Model Considering Metal Phases and Minimum Chip Thickness

Key Engineering Materials, 2008
In this paper, a micro milling model is brought forward. The influences of different metal phases and the minimum chip thickness are considered in the model. The cutting forces and the surface generation in the micro milling process are predicted. Through the experiment validation, the results correlate to the model very well.

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, 2018
The 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.

Influence of the main cutting edge angle value on minimum uncut chip thickness during turning of C45 steel

Journal of Manufacturing Processes, 2020
Abstract One of the important phenomena of orthogonal cutting process is the occurrence of the minimum uncut chip thickness, as its highly affects the process of cutting initiation and surface roughness. But nowadays non orthogonal i.e., oblique cutting process using special tools with continued cutting edge and high value of cutting angle λs make ...

Chip formation and surface integrity investigation considering the minimum uncut chip thickness in micro-helical milling

Journal of Materials Research and Technology
In micro-helical milling, the minimum uncut chip thickness (MUCT) plays a crucial role in governing chip formation and surface integrity. However, its precise determination and underlying influence mechanisms in micro-helical milling remain insufficiently explored.

Numerical Modeling of Minimum Uncut Chip Thickness for Micromachining With Different Rake Angle

ASME 2011 International Manufacturing Science and Engineering Conference, Volume 2, 2011
In micromachining, when the undeformed chip thickness becomes comparable to the edge radius of the cutting tool, the effective rake angle becomes to be negative and has significant effect on the determination of the minimum uncut chip thickness. The determination of the minimum uncut chip thickness is essential in micro machining in order to achieve ...
