Study of undeformed chip and cap geometries at three machining stages in the orbital drilling process

International Journal of Advanced Manufacturing Technology, 2019
The characteristics of undeformed chip geometries generated by a dedicated cutting tool are complex in orbital drilling of Ti6Al4V and they have an important influence on the quality of hole-making. This study investigates the orbital drilling kinematics and the undeformed chip geometry based on the definition of three machining stages.

Multiscale Predictive Modelling of Critical Undeformed Chip Thickness

2021
Predictive 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, 2013
The 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.

Shear Angle Relationship With Variable Undeformed Chip Thickness

Journal of Engineering for Industry, 1974
Effect of surface slope of the workpiece on shear angle has been considered by applying Hill’s [1] deformation criteria to the triangular shear zone in orthogonal metal-cutting process with variable undeformed chip thickness. It is shown that the variation of the shear angle with the surface slope δ can be written in the form φ = φ0 + Cδ where “C” is ...

Chip Formation With Varying Undeformed Chip Thickness at Very Slow Speed

Journal of Engineering for Industry, 1964
Steel S.A.E. 1112 cold rolled specimen was cut orthogonally at slow speed of 0.625 ipm, and the shear plane formation was examined from a series of photographs taken during a cut for cutting triangular wavy surface and for the case where the straight surface is cut by the tool moving along the triangular wavy path.

Determination Of The Undeformed Milling Chip Thickness by Circular Interpolation

Materials Technology, 2006
Manufactured part qualities are determined by their form errors and surface finishes produced by the manufacturing process. Cutting forces and process stability depend on the chip thickness which therfore intluences the surface quality. The determination of the instantaneous undeformed chip thickness plays a very important role in the modelling of ...

A Parametric Analysis of the Undeformed Chip Geometry in Gear Hobbing

Journal of Manufacturing Science and Engineering, 2009
Hobbing is a common manufacturing method when producing helical, involute gears. In order to increase tool life and surface finish, an accurate method to determine chip geometry is needed. Although this accurateness may involve numeric solutions, the geometric description must, as far as possible, be analytic and give a description of the continuously ...

Investigation of Undeformed Chip Thickness Model and Surface Roughness Prediction in Belt Grinding

Volume 2A: Advanced Manufacturing, 2022
Abstract Undeformed chip thickness plays a very important role in studying the materials remove mechanism in flexible belt grinding and predicting ground surface roughness. A calculation model that can be used to effectively predict the undeformed chip thickness in flexible belt grinding is established based on the height distribution of
