3D Continuum Modelling of PDC Cutting of Rock with a Simple Contact-Erosion Scheme
This paper presents a relatively simple numerical approach to predict the cutting force during PDC (polycrystalline diamond contact) cutting of rock. The rock failure model is based on a damage-viscoplasticity model, with the Drucker–Prager yield surface

Reliability assessment of cutting tools life based on advanced approximation methods [PDF]
Cutting tools' reliability influences the whole manufacturing efficiency. However, in most cases the same cutting tool may be used for different operations with different processing parameters, making thus difficult to estimate the remaining life of the ...

Simulation of the deflected cutting tool trajectory in complex surface milling [PDF]
Since industry is rapidly developing, either locally or globally, manufacturers witness harder challenges due to the growing competitivity. This urges them to better consider the four factors linked to production and output: quality, quantity, cost and

Cut finite elements for convection in fractured domains [PDF]
We develop a cut finite element method (CutFEM) for the convection problem in a so called fractured domain which is a union of manifolds of different dimensions such that a $d$ dimensional component always resides on the boundary of a $d+1$ dimensional component. This type of domain can for instance be used to model porous media with embedded fractures

3D characterisation of tool wear whilst diamond turning silicon [PDF]
Nanometrically smooth infrared silicon optics can be manufactured by the diamond turning process. Due to its relatively low density, silicon is an ideal optical material for weight sensitive infrared (IR) applications. However, rapid diamond tool edge

Cutting Forces Prediction in Ball End Milling [PDF]
In curved surface machining, parametric surface representation is normally used for computer aided design (CAD). Parametric surfaces are often machined using a flat end mill for roughing and ball end mill for finishing.
