Effect of machining-induced harden layer on wear resistance of Type316L austenitic stainless steel
In order to clarify the effect of surface hardening layers induced during machining processes such as cutting and grinding on the wear resistance of austenitic stainless steel SUS316L, a surface hardening layer was intentionally induced on SUS316L through lathe cutting. A ball-on-disk friction wear…

Proposed of a method to reduce motion error in linear interpolation tool-path based on estimated motion trajectories of machining center
In this paper, from the viewpoint of machining center (MC) users, we proposed a simple and convenient approach to reduce motion errors in tool-path consisting with linear interpolation commands in NC systems that use only linear acceleration/deceleration processing after interpolation. In a…

Parallel fluid analysis via machine-learning-based photogrammetry and a Nitsche-type immersed boundary method
This study proposes a fluid analysis system that automatically acquires geometric data from images, eliminating manual model generation for objects with complex geometries. Numerical simulation of natural fluid phenomena is essential in many applications; however, the lack of pre-existing geometric…

Quasi-two-dimensional Monte Carlo analysis of aggregate-structure transitions of hexagonal plate-like hematite particles
Monte Carlo simulations were performed for a quasi-two-dimensional dispersion of hexagonal plate-like hematite particles to investigate aggregate-structure transitions and their internal structures. The analysis was limited to a quasi-two-dimensional model in which particle centers were confined to…
