Grinding Wheels•The surface of grinding wheels are made up of these grains.
•Grains have random irregular shapes that are located at the edge of the grinding wheels.
Grinding FormulaL = (Dd)
Undeformed length = (Diameter)(depth)
Grinding Almost any material can be ground -
aluminum, steel, ceramics, even diamond or glass.
Electrical discharge machining Erosion of metals
by spark discharge Capacitor discharge
is between 50 and 380 V
EDM can be used on any material that is an electrical conductor
• Uses an electrode that sends out the sparks which erodes the metal
• Uses dielectric fluids for cooling and flushing of the material
• EDM wire • Wire is brass,
copper or tungsten• With wire edm you
can basically cut out any design
