Linkage numerical control exhibits 4 axes to electroanalysis the development of grinder

Integral impeller is rocket motor, aircraft engine and aviation one of important parts of airborne equipment. Integral impeller job is below condition of high temperature, high pressure, high rotate speed, choose material to be the difficult cutting material such as alloy of heat-resisting of stainless steel, high temperature and titanium alloy more, it is integral structure plus its, contain complex model the lamina of the face, make its production very difficult, become aviation to make the key in the technology.
Current, the production method of integral impeller has nicety to cast, numerical control mill and non-traditional machining. No matter use which kind of methods, mental allowance is bigger, the body that should lean surplus of manual polish purify to achieve blade profile commonly, dimension precision. Manual polish basically exists a few more the following problem: Blade profile precision assures hard, percent defective is tall: Level of requirement worker craft is high: Labor productivity is low, cost is high: Worker work requirement is abominable, noise is big, dust pollution is serious, and accident of easy occurrence inductrial injury. Use numerical control of much axis linkage to be exhibited electroanalysis the finish machining problem that grinding can solve integral impeller well.
Linkage numerical control exhibits 1 4 axis to electroanalysis grinding machine tool
Exhibit motion to analyse to realize integral impeller complex model of the face electroanalysis grinding treatment, electric conduction wears round of look to workpiece exhibiting movement must be much axis linkage. Exhibit movement dissoluble move point-blank to 3 for X, Y and Z heft and two rotational heft that circle Z axis and Y axis, among them linkage of axis of X of need of heft of before 4 motion, the last for divide evenly fast roll (graph 1) .

Exhibit athletic implementation
The basis machines the requirement of integral impeller, already designed, make numerical control of many axis linkage electroanalysis grinder (win a state practical and new-style patent, patent date: 96231072.7) . The function of orgnaization of motion of this machine tool is as follows (graph 2) :
Electric conduction wears round of look heft of sharp to the Z axis direction of workpiece movement, the sharp movement that grinds round of stretch bearing to drive electric conduction to grind round of edge Z axis by machine tool electric conduction will come true (0.0005mm/ pulse) :
Electric conduction wears round of look heft of sharp to the X axis direction of workpiece movement, the sharp movement that drives axis of workpiece edge X by machine tool workbench will come true (0.001mm/ pulse) :
Electric conduction wears round of look heft of sharp to the Y axis direction of workpiece movement, the sharp movement that drives axis of workpiece edge Y by machine tool workbench will come true (0.001mm/ pulse) :
