Objective: Biomechanical simulation requires accurate representation of the geometry of the structures to be studied. Specifically, when simulating the interaction of implanted prosthetics with surrounding tissues, the geometric and mechanical properties of the prosthesis and the surrounding tissues need to be adequately represented. The present work describes methods for inserting test prosthe...

background and objectives: pomegranate juice (pj) contains large particles that stick to evaporator walls causing off flavors in the concentrate due to burning. microfiltration is used to clarify pj. fouling is a limiting phenomenon that can prevent the industrialization of membrane clarification. changes in the geometry of the membrane module such as using baffles are useful to decrease this p...

Preliminary notes This paper aims to establish the parameters of optimization and geometrical improvements for the micro-geometry of solid carbide drills through the application of sand blasting process. The effects of sand blasting over the cutting edge and also upon the micro geometry of the tool body are to be taken into consideration. This process is one of the most common ones used in the ...

In this paper, a method integrating NC decoding and solid milling simulation to solve this problem is proposed. A modified Z-Map computational algorithm is adopted and it directly uses straight line and arc interpolation algorithms to calculate mesh position and Z coordinates of tool scanning surface according to tool path and initial tool scanning boundary in reducing the long computation time...

Tool wear, minimum chip thickness and micro tool geometry are found to have a significant influence on the surface roughness through experimental analysis of the micro-end-milling process. To address these issues, a surface roughness model is developed and validated in this present work. Firstly, experimental analysis for the tool wear and surface roughness was performed based on the micro-end-...

The side flow of material in nano cutting is one of the most important factors that deteriorate the machined surface quality. The effects of the crystallographic orientation, feed, and the cutting tool geometry, including tool edge radius, rake angle and inclination angle, on the side flow are investigated employing molecular dynamics simulation. The results show that the stagnation region is f...

Inconel 718 is widely used in aircraft industry due to its properties. Nevertheless, mechanical and chemical properties make it hard-to-cut. As a consequence, additive manufacturing developed order get near net shape part before machining. Thus, this article presents study on the machinability of obtained by compare one from wrought bar. Firstly, milling investigated through microstructure obse...

This paper uniies most of the current literature on 3D geometric invariants from point correspondences across multiple 2D views by using the tool of Elimination from algebraic geometry. The technique allows one to predict results by counting parameters and reduces many complicated results obtained in the past (reconstruction from two and three views, epipolar geometry from seven points, triline...
