Abstract
In this paper a kind of machine-electrochemistry method with a new bined tool has been studied. During the period, the essential theory of the machine—electrochemistry method has been systemic model has been established. Base on this,a
kind of new bined tool had been developed,the test equipment has been designed and built up,and an inVestigation has been made into the polishing and cutting f色asibility of hard materials when the new machine-electrochemistry method is adopted.
First of a11,the essential theory of the machine—electrochemistry method has been analysed, and the systemic modeI has been established.
Secondly,a kind of new bined tool had been developed, This new t001 is made up with the inner electrode and the external helical abrasives. The new structure of this bined tool
produces screwy eff色cts of electrochemistry and grind through the movement of new kind of tool has been used to polish some kinds of hard materials such as Die Steel and
Hard A110y.
Thirdly,the test equipment has been designed and built up by the refit of a WEDM—HS machine and a drilling circle system, worktable and feed contr01 system of WEDM—HS machine,and the turning system of the drilling machine have been arranged in pairs or
口oups.
Finally large numbers oftest has bee 0ne hand,This new kind of tool has been used to polish some kinds of hard materials
such as Die Steel,Stainless Steel and Hard machining,the
surface quality and mechanical performance of the specimens are studied. The exDerimental results show that this Machine-electrochemistry method can improVe the surface roughness and decrease surface cracks additional,there are no wastage of the tool that can be fbunded during the process. Finally an
orthogonal design is adopted to optimize the process parameters so as to obtain the best integrative expe riment reVeals that it is a feasible an
