3-D finite element modeling of sequential oblique cutting of unidirectional carbon fiber reinforced polymer

Composite Structures, 2021
Machining of carbon fiber reinforced polymers (CFRP) such as milling and drilling is in the form of oblique and sequential cutting at the tool edge. The material removal mechanism and surface quality are highly dependent on the fiber orientation and ...

Development of a friction model based on oblique cutting theory

International Journal of Mechanical Sciences, 2019
As turning is a 3D operation, development of a friction model considering all cutting forces and angles, is essential. In this study, shear friction model is extended based on oblique cutting theory.

A study of oblique cutting for different low cutting speeds

Journal of Materials Processing Technology, 2001
Abstract In this paper, the finite deformation theory and an updated Lagrangian formulation (ULF) were used to describe the oblique cutting process. Either the tool geometrical location condition or the strain energy density constant was combined with the twin node processing method to be adopted as the chip separation criterion.

Burr formation and fracture in oblique cutting

Journal of Materials Processing Technology, 1996
Industrial summary To improve productivity in the machining of parts, advanced technology for deburri~g becomes more important. In a computer-integrated manufacturing system, the prediction of burr formation or fracture is required. To apply a burr-formation model for orthogonal cutting to a realistic oblique-machining case, a modified model for burr ...

Study and analysis on cutting forces of oblique cutting of wood

European Journal of Wood and Wood Products, 1996
The objective of the experiments in this paper is to find out the relationship between cutting forces and oblique angles of cutting edge. The experiment consists of 90°−0° and 0°−90° oblique cutting situations. Each type of experiment includes two wood species and two kinds of chip thickness.

FE-SPH hybrid method to simulate the effect of tool inclination angle in oblique diamond cutting of KDP crystal

International Journal of Mechanical Sciences, 2021
Due to the soft and brittle characteristic, the potassium dihydrogen phosphate (KDP) crystal undergoes a complex process in diamond cutting, which makes the material removal mechanism is still a subject of controversy.

Determination of Cutting Forces in Oblique Cutting

Applied Mechanics and Materials, 2015
This study describes the method of determining cutting force components in oblique turning. The scheme of how the investigations were performed is presented. The characteristic curves of cutting force components vs. thickness of the material removed, tool clearance and tool rake angles are shown.

Thermomechanical modelling of oblique cutting and experimental validation

International Journal of Machine Tools and Manufacture, 2004
Abstract An analytical approach is used to model oblique cutting process. The material characteristics such as strain rate sensitivity, strain hardening and thermal softening are considered. The chip formation is supposed to occur mainly by shearing within a thin band called primary shear zone.
