Shear Angle Relationship With Variable Undeformed Chip Thickness
Journal of Engineering for Industry, 1974Effect 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 ...

Investigation of Undeformed Chip Thickness Model and Surface Roughness Prediction in Belt Grinding
Volume 2A: Advanced Manufacturing, 2022Abstract 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

Determination Of The Undeformed Milling Chip Thickness by Circular Interpolation
Materials Technology, 2006Manufactured 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 ...

Chip Formation With Varying Undeformed Chip Thickness at Very Slow Speed
Journal of Engineering for Industry, 1964Steel 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.

This paper carries out a finite element (FE) analysis to investigate the effects of grinding speed (20∼400 m/s) and undeformed chip thickness (1∼8 μm) on chip formation dur- ing single grain grinding of nickel-based superalloy Inconel 718. Three factors related to the Johnson-Cook (J-C) consti- tutive model, i.e., the strain hardening, strain-rate ...

In this study, effects of the maximum undeformed chip thickness on roughness of ground surface and specific grinding energy were investigated. The acoustic emission (AE) signals generated during grinding processes have been analyzed to find out the appropriate AE parameters for assessing the processes.

Model of the instantaneous undeformed chip thickness in micro-milling based on tooth trajectory
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2016Instantaneous undeformed chip thickness is one of the key parameters in modeling of micro-milling process. Most of the existing instantaneous undeformed chip thickness models in meso-scale cutting process are based on the trochoidal trajectory of the cutting edge, which neglect the influences of cutter installation errors, cutter-holder manufacturing ...

Critical undeformed chip thickness of brittle materials in single point diamond turning
The International Journal of Advanced Manufacturing Technology, 2015In this work, the ultimate compression force that enables the plastic removal of brittle materials in diamond turning is initially modeled according to the theory of rigid-plastic mechanics. And subsequently, an independent oscillator model is reconstructed to calculate the microfriction force that appears at contact interface.
