By the CFD(computational fluid dynamics) software FLUENT, the abrasive flow shape during abrasive flow machining(AFM) was simulated by the Spalart-Allmaras model which is a Mixture turbulent flow model for solid-fluid two phase flow system.

New development and current state for high speed and super-high speed abrasive machining;

Abrasive machining plays an important role in precision and ultra-precision processing technology.

In this paper, semi-fixed abrasive machining technique is proposed and it can reduce or eliminate the surface damage caused by large abrasive gains, which will improve the efficiency of precision or ultra-precision processing.

Abrasive flow machining (AFM) is a nontraditional finishing process that is used to deburr , polish, radius and remove recast layer by flowing a semisolid abrasive media across the workpiece surface.

The viscosity of flowable abrasive mixture is an important parameter in abrasive flow machining(AFM).

Introduced the principle and machining characteristics of abrasive flow machining, analyzed applicability and high efficiency of abrasive flow machining in various plastic molding mold, mainly introduced machining skill and clamp design points of various mold parts.

Development and key technologies for high efficiency abrasive machining;
