Modeling and Experimental Analysis the Effect of Minimum Chip Thickness on Cutting Temperature in Micro-End-Milling Process

Advanced Materials Research, 2010
In this paper, the effect of minimum chip thickness on cutting temperature in micro-end- milling of aluminum alloy Al2024-T6 using a tungsten-carbide cutter are investigated and analyzed. The three-dimensional coupled thermal-mechanical finite element model is adopted to determine the effects of varying depth of cut on cutting temperature considering ...

Determination of minimum uncut chip thickness in mechanical micro-machining using Johnson-Cook fracture model

International Journal of Mechatronics and Manufacturing Systems, 2013
In mechanical micro-machining (MMM), the tool edge cannot be considered to be sharp due to the finite edge radius observed at the micro-scale. The uncut chip thickness is comparable to the tool edge radius and sometimes it is less than the tool edge radius. In MMM, below certain critical uncut chip thickness, only elastic deformation takes place and no

Experimental Investigation on the Influence of Tool Geometry in Minimum Chip Thickness of Microendmilling Using Cutting Force Analysis

2020
Minimum uncut (tm) chip thickness is the promising factor of the microendmilling process, which is affected by many factors. The tool geometry is one among them. In this work, the effect of different tool geometries, two flutes and four flutes of microendmill (500 μm diameter), are investigated, during slot milling of copper alloy (BSS 249) by ...

Minimum Chip Thickness Model and Size Effect in Zirconia Ceramics Nanofluid MQL Grinding

To address the current bottleneck of debris formation mechanism in plastic removal for hard-brittle materials, a minimum chip thickness (hmin) model that considers lubrication conditions (represented by frictional angle β) is developed according to strain gradient, as well as geometry and kinematics analyses. Model results show that hmin decreases with
