Abrasive flow finishing (AFF) Finishing is final operation involved in the manufacturing of components and is most labour intensive, time consuming and least controllable. The surface finish with the traditional honing is achieved to 653 nm from the initial machined surface roughness of 2520 nm in 40 min of finishing. The final surfaceTitanium (Ti) alloys are mainly used in medical implants and aerospace applications where high fatigue strength is significant. Most of the titanium based components are subjected to unconventional machining to get the final shape of the product. Because, Ti based alloys are very challenging to machine using conventional processes. Experimental investigation on microstructural

It can be seen from Fig. 11 that the machined surface roughness under different abrasive patterns drops with the increase of the wheel rotating speed and the coolant pressure. For the random pattern A, when the rotating speed is increased from 1000 to 3000 r/min, the machined surface roughness is reduced from 1.28 to 0.75 μm and The media gets the rotating and reciprocating motion with the help of rotating magnetic field to achieve the mirror finish.

Introduction. Grinding is one of the machining methods by using the abrasive grains to achieve high-efficiency and precision machining of mechanical components. The grinding process is achieved by a grinding wheel consisting of abrasive grains held together with special bonding material. The actual cutting points of abrasive A correlation between machining process and fatigue strength of machined components clearly exists. However, a complete picture of the knowledge on this is not readily available for practical applications.

Then, the interaction influence of grinding parameters on the SR and SSD depth is analyzed using the response surface method (RSM). The grinding speed (v s), grinding depth (a p), and feed rate (f) vary from 6–14 m/s, 1–5 μm, and 10–50 μm/s, respectively.The grit size of the abrasive grain (d g) used in the RSM experiments is 7 Tan et al.

CNC surface finish and finishing methods are particularly important if your part is in contact with other components. For example, the purpose of a ball-bearing is to reduce rotational friction and support radial and axial loads. When one of the races rotates, the balls also rotate because of the contact between them.Abstract. Loose abrasive machining is one of the processes, which contributes to improving precision, such as surface roughness and form accuracy of manufactured components. To date, numerous process principles have been developed to materialize the loose abrasive machining process in different ways. These developments Loose Abrasive Machining SpringerLink

For the in-feed superfinishing in Fig. 19a, the machined bearing roller is in touch with two guide rollers rotating in the same direction. The abrasive stone is on the right above the bearing roller. In the machining process, the abrasive stone oscillates with high frequency and small amplitude along the axial line of the bearing roller.Therefore, components have to be post-machined. Lately, abrasive flow machining (AFM) is offering improvements in such cases. However, many process parameters, e.g. abrasive media property, temperature, velocity, etc. influencing the performance of AFM and their understanding is crucial for successful implementation of Abrasive Flow Machining of 3D Printed Metal Parts Springer
