Modelling High Speed Machining with the SPH Method [PDF]
, 2008 The purpose of this work is to evaluate the use of the Smoothed Particle Hydrodynamics (SPH) method within the framework of high speed cutting modelling. First, a 2D SPH based model is carried out using the LS-DYNA® software.

Lee-Shaffer's Type Solution for Oblique Cutting
Journal of the Japan Society of Precision Engineering, 1974 The plastic deformation in oblique cutting is considered as a modification of plane plastic flow, since there are no variations of stresses and velocities in the direction parallel to the cutting edge. Based upon this nature, the characteristics of the velocity field are obtained and the relations in stress and velocity along the characteristics are ...

The Binary Space Partitioning-Tree Process [PDF]
, 1988 The Mondrian process represents an elegant and powerful approach for space partition modelling. However, as it restricts the partitions to be axis-aligned, its modelling flexibility is limited.
