Possibilities of 3D machining of materials by abrasive water jets [PDF]

open access: yes, 2019
Machining of materials through classical way, i.e. using conventional tools for turning, drilling, milling, grinding and polishing, has some limits that can be overcome applying an abrasive water jet (AWJ). Therefore, some possibilities of 3D machining

Modelling of dishing for metal chemical mechanical polishing [PDF]

open access: yes, 2000
In this paper, a physical model for the development of dishing during metal chemical mechanical polishing (CMP) is proposed. The main assumption of the model is that material removal occurs predominantly at the pad/wafer contacts. The distribution of pad/

A Study on the Abrasive Gels and the Application of Abrasive Flow Machining in Complex-hole Polishing

open access: yesProcedia CIRP, 2017
Due to the fact that abrasive media can deform flexibly in abrasive flow machining (AFM) making this method easily to polish the complex holes and the curved surface of the hard machining shapes. Although abrasive media dominate the polishing behavior in AFM process, the mechanism of the abrasive media are not easy to understand because of the high ...

Study of the Polishing Characteristics by Abrasive Flow Machining with a Rotating Device

open access: yesProcesses, 2022
Since only uni-direction motion is produced by traditional abrasive flow machining (AFM), so the polishing effects of the inner hole is not easy to achieve uniform roughness of the whole surface after polishing. Therefore, in this study, a rotating device with a DC servo motor was set up in the AFM to increase the tangential forces on the machining ...
