Modeling and simulation of the distribution of undeformed chip thicknesses in surface grinding
International Journal of Machine Tools and Manufacture, 2018Abstract The distribution of undeformed chip thicknesses is the kinematic “copy” of grain space distribution on a workpiece and has an important influence on the grinding results. In this study, a wheel topography model is developed that can be integrated with a workpiece model, a kinematic model and a calculation model of undeformed chip thickness ...

Abstract Vibration-assisted machining (VAM) of brittle materials has been proved to be useful in improving the machining performance by significantly increasing the critical undeformed chip thickness for ductile–brittle transition. However, until now, there does not exist any viable method or model to predict the critical undeformed chip thickness in

Abstract The precise modeling of the instantaneous undeformed chip thickness is one of the key issues in the mechanics of micromilling. While most current models noticed the influences of the tool tip trochoidal trajectory and tool runout, they took account only the workpiece removed by immediate passing tooth but not more preceded teeth.

Abstract The development of modeling and predicting grinding force and energy has great significance in improving tool life and grinding efficiency. As an important parameter to study the grinding mechanism, the undeformed chip thickness catches more and more attentions in modeling the grinding process, and the investigation on its nonuniformity ...

Abstract The grinding force and power play an important role in ceramic grinding process as they not only have the direct influence on the wheel wear, grinding accuracy, grinding temperature and surface integrity but also have strong influence on local contact deflection and the nature of the contact deflection that has an important effect on the ...

Multiscale Predictive Modelling of Critical Undeformed Chip Thickness
2021Predictive modelling of critical undeformed chip thickness (tc) is important for ultra-precision machining of brittle materials in a ductile mode. This paper presents a hierarchical multiscale modelling approach that is capable of quantitatively predicting the variation of tc with crystal orientation. The proposed multiscale modelling approach consists

Determination of the Chip Width and the Undeformed Chip Thickness in Rotational Turning
Key Engineering Materials, 2013The accurate knowledge of the defining parameters of chip removal in rotational turning is necessary for the description of the complex kinematic relations. In this paper two characteristic parameters of the chip cross-sectional area undeformed equivalent chip thickness, chip width is defined.
