Question

275. In electro-chemical milling operation, the gap between tool and workpiece is filled with
O (A) 0.75 mm
0 (B) 5 mm
O (C) No gap
O (D) 0.25 mm​

Answer 1

The gap between the tool and the workpiece varies within 80–800 micrometers (0.003–0.030 in.) As electrons cross the gap, material from the workpiece is dissolved, as the tool forms the desired shape in the workpiece. The electrolytic fluid carries away the metal hydroxide formed in the process.
