ABSTRACT

Cutting spiral drain in deep hole is actually one of the most complex problem in armament

manufacturing. Electro-Chemical cutting is one usual method of manufacturing in the mechanical plants

for cutting different formed holes which can not realized by others methods. Quality of Electro-chemical

cutting depends on many factors. For achieving of technical requirements of artillery, there is a

concentration into three factors most influenced to surface quality and productivity of metal eliminating

as following: Density of current, density of electro- chemical solution and temperature of cutting zone.

On this knowledge we can determinate optimal cutting parameters for obtaining good productivity with

required surface quality.
