Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction.
In forming processes, such as molding or metal forming, surface finish of the die determines the surface finish of the workpiece. In machining, the interaction of the cutting edges and the microstructure of the material being cut both contribute to the final surface finish. [citation needed] In general, the cost of manufacturing a surface ...
Superfinishing, also known as microfinishing [1] and short-stroke honing, is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer of fragmented or smeared metal left by the last process with an abrasive stone or tape; this layer is usually about 1 μm in magnitude.
A honing machine is a precision tool used in machining to improve the surface finish and dimensional accuracy of component. It operates by using abrasive honing tools, which rotate and reciprocate inside the components, typically a cylinder or bore. This process enhances the internal surface quality, achieving precise dimensions and smooth ...
Manufacturing processes have five main variables: the workpiece, the tool, the machine tool, the environment, and process variables. All of these variables can affect the surface integrity of the workpiece by producing: [3] High temperatures involved in various machining processes; Plastic deformation in the workpiece (residual stresses)
Abrasive flow machining (AFM), also known as abrasive flow deburring [1] or extrude honing, [2] is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a workpiece. [1] [3] [2] This fluid is typically very viscous, having the consistency of putty, [2] [3] or dough. [1]
Magnetic field-assisted finishing (MAF) processes have been developed for a wide variety of applications including the manufacturing of medical components, fluid systems, optics, dies and molds, electronic components, microelectromechanical systems, and mechanical components.
Surface grinding is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose.
