Material properties were modified.
Also because electric field strength of (b) mode is stronger, the energy used to breakdown coatings is more sufficient on unit area, then, discharge channels are constantly generated, from which more molten materials are erupted out, Fig.2 just verify the difference.

Among the research, the bio-diesel has greater prospects, because of its extensive system of taking raw materials, process optional good without replacing or modifying the engine.
Furthermore, the emissions generated particulate, hydrocarbon materials, sulfur dioxide and other substances reduce significantly, which is good for environmental protection.

The energy generated per unit volume of material removal during grinding is much bigger than for other conventional machining operation [1], and virtually all of this energy is converted to heat within the grinding zone.
The total grinding heat flux can be defined as fchswt qqqqq +++= (8) and where c st c t lb VF lbP q ⋅ ⋅ = ⋅ = (9) and the heat flux to the workpiece wq , wheel sq , fluid fq and chips chq may be expressed in terms of convention/conduction factors defined in relation to maximum contact temperature under fluid condition maxT and material melting temperature mpT as follows: maxThq ww ⋅= , maxThq ss ⋅= , maxThq ff ⋅= , mpchch Thq ⋅= (10) Where flux to the chips was estimated from the limiting chip energy to raise the chip material close to melting, taking the mean value of specific heat from ambient temperature to melting point, the limiting chip energy is approximately 6 J/mm 3 for ferrous materials [5, 8].

Referring to the reference presented by Fu [9], the normal contact force defined in ADAMS is represented as the following equation: (1) where STEP is the function for simulation step control, is the displacement avriable, is the velocity variable, is the initial displacement where contact occurs, denotes the stiffness coefficient, C denotes the dampling coefficient, is the penetration depth of contact surfaces (dampling will target the setting value over this depth), is the stiffness curve exponent, in experience, 2.2 for hard metal materials, 1.5 for soft metal mateirals, 1.1 for rubber materials.
Steel material properties using in the paper are listed in Table 2.
