AFM is a non-traditional machining process that uses a semi-solid abrasive media to remove material from the workpiece. The abrasive media is forced through the workpiece using hydraulic pressure, which helps to remove burrs, polish surfaces, and improve surface finish.The process is typically used for finishing complex internal shapes and hard-to …
The theory is independent of the size and material of the workpiece and the design of the magnetic abrasive machine tool. The theory results are verified experimentally. The limiting accuracy of the magnetic abrasive process, the machining time required to achieve specified accuracy of the workpiece, and the material removal rate are determined.
The dependence of normal and tangential maximum forces to the process parameters can be observed on Fig. 8. First, it must be noticed an increase in the forces with increasing maximum depth of cut. This result is in agreement with those related in the literature [4] for lower speeds and depths of cut. Nevertheless the variations of the forces ...
