A titanium sheet of 5.0 mm thickness is cut by wire-cut EDM process using a wire of 1.0 mm diameter. A uniform spark gap of 0.5 mm on bothsidesof the wire is maintained during
cutting operation.If the feed rate of the wire into the sheet is 20 mm/min, the material removal rate $$(in \frac{mm^{3}}{min})$$ will be
