Deformation During Chip Formation

Journal of Engineering for Industry, 1965
Expressions are derived for the deformed orientation of an initially rectangular grid and the direction of maximum elongation with respect to the rake face of the tool in orthogonal machining.

Chip Formation in Cellular Materials

Journal of Engineering Materials and Technology, 2002
The constitutive behavior of cellular materials like wood, especially with respect to the plastic and fracture mechanical properties, differs significantly from that of “classical” materials like steel. From this point of view, it appears interesting to investigate a process like chip formation, where both plasticity and fracture intervene.

Chip Formation With Chamfered Tools

Journal of Engineering for Industry, 1982
The paper deals with the effect of chamfers on the tool edge on the chip formation process. It is found that both in continuous cutting and in the exit phase of interrupted cutting where chamfers are mostly used the chip formation process is not very different from that obtained with nonchamfered tools.

Dynamic Aspects of Chip Formation

Russian Engineering Research, 2018
A multimass chain model of chip formation in the secondary deformation zone is proposed. The influence of the frictional conditions and cutting conditions on the group motion of the chip elements over the cutter’s front surface is shown. The dynamics of the motion of the chip’s free end has a significant influence on its fracture.

Mechanics of Chip Formation

1989
Abstract The relative motion between the tool and the workpiece during cutting compresses the work material near the tool and induces a shear deformation that forms the chip. This article discusses the fundamental nature of the deformation process associated with machining.

Chip Formation in the Cutting of Composites

Russian Engineering Research, 2020
The machining of composites is of great importance in manufacturing. In particular, there is a need to calculate the cutting force and predict the surface quality of composite workpieces. In the present work, the SPG and SPH methods are used to simulate the cutting zone of a unidirectional fiber-reinforced composite and particle-reinforced composite ...

A Microscopic Study of Chip Formation

Journal of Engineering for Industry, 1964
This paper is a report on an improved technique to study the formation of chips while observing them through a metallurgical microscope. By using polished and etched specimens it is possible to see the formation of slip lines in front of the tool as plastic deformation initiates.

Mechanics of chip formation in cutting

Russian Engineering Research, 2017
The stress–strain state in chip is investigated by the finite-element method. In addition, the cutting process and the mechanics of chip formation are studied experimentally over the whole temperature range of metal cutting.

Chip Formation in Orthogonal Cutting

1999
This paper is the result of a cooperation between the Institute for Production Engineering and Machine Tools (IFW), University of Hannover, Germany and the Department of Mechanical Engineering of the University of Brescia, Italy. The aim of the work is to validate the reliability of a Finite Element code in simulating orthogonal cutting operations ...

Theory of Formation of Metal Chips

Journal of Applied Physics, 1948
In this article values for the angles β and ν have been deduced (compare Fig. 3 and Eqs. (2) and (3)). New values have been deduced for the shear angle φ, Eqs. (16), (20), and (21). The increasing of the internal friction and the strain hardening have been considered. Equations for the work done in cutting per unit of length (6) and (13)
