The materials upon the point P were rise up along rake face.
In simultaneity, the materials below the point P were flowed towards to flank face and formed the machined faces. θ is the position angle of point P.
The rake force was generated mainly from three sources: the force of spring back of workpiece materials, the force of plastic formation of workpiece materials and the force of friction between chip and tool rake face.

Material and Calculation Model
Material Model.
The calculation model of top-air-decking charge structure is shown in Figure 1; the calculation model consists of three materials: explosives, rock(quartz sandstone, muddy shale) and air.
Stem uses quartz sandstone materials to simplify the calculation.

Experimental
Materials Polyethylene glycol (PEG) (Gaonan chemical plant, south of Shanghai Pudong, China).
All the chemicals and materials were commercially available as guaranteed-grade reagents and used without further purification and treatment.
It was observed that swelling ratio of the materials increased with PEG percentage rising.
