    After compression, the part shears for about 10% of the part thickness, and then fractures free of the strip or sheet. This fracturing produces a raised, jagged edge which is called a "burr". Burrs are typically removed by tumbling in a secondary process. Burr height can be used as an important indicator of tool wear.

  3. Surface finishing - Wikipedia

    en.wikipedia.org/wiki/Surface_finishing

    One takes great care to remove any surface defects in the metal, like pits, that could allow bacteria to grow. A #4 dairy or sanitary finish is produced by polishing with a 180–240 grit belt or wheel finish softened with 120–240 grit greaseless compound or a fine non woven abrasive belt or pad.

  4. Burr (edge) - Wikipedia

    en.wikipedia.org/wiki/Burr_(edge)

    Metal burr extending beyond the edge of the cut piece, view on the cut face (top) and from the bottom (bottom) A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. [1] It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring.

  5. Burnishing (metal) - Wikipedia

    en.wikipedia.org/wiki/Burnishing_(metal)

    It is especially useful for removing the burr in the middle of a through hole that was drilled from both sides. [ 1 ] Ball burnishing tools of another type are sometimes used in CNC milling centres to follow a ball-nosed milling operation: the hardened ball is applied along a zig-zag toolpath in a holder similar to a ball-point pen, except that ...

    Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.

  7. Curling (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Curling_(metalworking)

    Curling is a sheet metal forming process used to form the edges into a hollow ring. Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end. [ 1 ] Other parts are curled to perform their primary function, such as door hinges .

  9. Electropolishing - Wikipedia

    en.wikipedia.org/wiki/Electropolishing

    Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
