2018年6月1日 · The developed framework determines the ranking of feasible NTM processes such as AJM–USM–AWJM–WJM–ECM-dry EDM–EDM-die sinking EDM–CHM–EBM. It is observed that AJM is the best machining process for generating standard cavity on Zirconia.

2019年6月12日 · Mechanical energy based non-traditional machining (NTM) processes directly utilize mechanical energy to gradually remove material from the workpiece primarily by erosion. Examples of such processes include abrasive jet machining (AJM), water jet machining (WJM), abrasive water jet machining (AWJM) and ultrasonic machining (USM).

2022年7月30日 · The AWJM is a hybrid NTM process in which the working principles of AJM and WJM are synergically integrated to remove material mainly from brittle materials (glass and ceramics). In this process, abrasive particles, like SiC, B 4 C, etc., proportionately mixed with water, are passed through a small nozzle and ejected on to the workpiece surface ...

2024年3月31日 · It discusses how AJM works by using a high-velocity jet of abrasive particles carried by a gas to remove material through micro-cutting and brittle fracture. The key process parameters of AJM like abrasive type and size, gas properties, and …

This document provides an introduction to Non-Traditional Manufacturing Processes (NTM), specifically focusing on Abrasive Jet Machining (AJM) as a representative method. It delineates the characteristics that differentiate conventional machining from non-traditional methods, classifies various NTM processes, and explores the mechanisms and ...

Machining (AJM) • In AJM, the material removal takes place due to impingement of the fine abrasive particles. • The abrasive particles are typically of 0.025mm diameter and the air discharges at a pressure of several atmosphere.

In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity. The high velocity abrasive particles remove the material by micro-cutting action

Non-Traditional Machining (NTM) Processes are characterized as follows: Material removal may occur with chip formation or even no chip formation may take place. For example in AJM, chips are of microscopic size and in case of Electrochemical machining material removal occurs due to electrochemical dissolution at atomic level

In this paper, a decision guidance framework is developed in Visual BASIC 6.0 to help the process engineers in selecting the most appropriate NTM process for a specific work material and shape feature combination. It also assists in identifying the ideal process parameter combinations for the most suitable NTM process.

The presence of a number of available non-traditional machining (NTM) processes has brought out the idea of selecting the most suitable NTM process for generating a desired shape feature on a given work material. This paper presents a digraph-based approach to ease out the appropriate NTM process selection problem.
