Abstract

The invention discloses a numerical control machining method for a large-size entire magnesium alloy casting. By researching the processing mode and the technique for the large-size entire casting and starting from the casting design, casting marking identification and casting numerical control machining, the invention analyzes the key points and designs the whole technological process, so that the difficulty in numerical control machining for the large-size entire casting is overcome. The numerical control machining technique for the large-size entire magnesium alloy casting is researched and an advanced and controllable processing mode instead of the traditional workshop style processing mode is adopted for the casting processing technique, so that the high quality and high efficiency of the casting numerical control machining are practically realized.

Description

The numerical-control processing method of large-scale integral Mg alloy castings
 
Technical field
The invention belongs to casting technology field, be specifically related to a kind of numerical-control processing method of large-scale integral Mg alloy castings.
 
Background technology
Current Computerized Numerical Control processing technology is widely used in machinery manufacturing industry, and obtains applying more widely in aircraft industry system.In recent years, along with scientific progress and development, in manufacture field, be all for Computerized Numerical Control processing technology development provides good development space on appointed condition or technical support.Magnesium alloy because itself is lightweight, good manufacturability, be convenient to the features such as machinability, be widely used in the control system of aircraft.And magnesium alloy still adopts in casting process major part is the traditional approach of sand-cast, tolerance due to casting deviation that is large and casting benchmark brings very large difficulty to digital control processing, because the ZM5 strength of materials is low, corrosion resistance is poor, the features such as burning-point is lower, need in process to carry out technology controlling and process.
 
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of numerical-control processing method of large-scale integral Mg alloy castings is provided, reduce workman's clamping times to greatest extent.
The numerical-control processing method of large-scale integral Mg alloy castings provided by the invention, comprises the following steps:
(1) part process is analyzed, determine machining benchmark, formulate processing scheme: a large plane in place of part is machining benchmark plane, processing route: pincers worker polishing datum level-with casting origin reference location scribing inspection each position surplus of foundry goods whether evenly-tie face-roughing band groove face by benchmark to make datum hole-turn-over roughing part profile and side-fine finishining band groove face-measurement profile-turn-over precision-machined parts profile flank hole-measurement profile hole position-pincers worker finishing-fluoroscopy-surface treatment-transfer;
(2) selection of location, fixture scheme: frock paves enough height, selects with adjustable locating piece in both sides, is beneficial to according to foundry goods different conditions adjustment locating surface position;
(3) selection of lathe: adopt five-axis machine;
(4) establishment of numerical control program: adopt Multi-Axis Sweeping to work out during processing profile, when processing deep trouth, roughing adopts Sweep Roughing to work out;
(5) selection of cutter: choose the milling cutter that few, the large anterior angle of the number of teeth, larger relief angle and helical angle are larger.
The numerical-control processing method of large-scale integral Mg alloy castings provided by the invention, its beneficial effect is, VERICUT can load woollen model and the information that designs a model simultaneously, so after emulation is cut, cross to cut and be very intuitively reflected in face of everybody with the remaining result checked, very clearly can grasp the quality of parts program establishment.After program composition, in order to reflect the processing situation of part accurately, some data importings of the lathe of being correlated with by field survey, frock, cutter and woollen are demonstrated in simulation software VERICUT, constantly adjust according to demonstration result, all problems is exposed fully before part processing and solves, final guarantee program not only not cut wound part, do not stay residual, and do not interfere with frock, lathe, not super machine tool travel; And the position of frock on lathe is clearly indicated in code, accomplish to reduce workman's clamping times to greatest extent.
 
Detailed description of the invention
Below in conjunction with an embodiment, the numerical-control processing method of large-scale integral Mg alloy castings provided by the invention is described in detail.
Embodiment
The numerical-control processing method of the large-scale integral Mg alloy castings of the present embodiment, comprise the following steps: get part exterior contour be of a size of 700mm × 620mm × 400mm, the X, Y, Z axis stroke using lathe is 8000mm × 3000mm × 1000mm, A pivot angle is-100 ° ~+100 °, C pivot angle is-360 ° ~+360 °, the frock used is 820mm × 700mm × 300mm, the processing stroke of lathe can process this part on the surface, but because the profile angle of part changes greatly, cause part portion in reality processing to add the excess of stroke in man-hour.For the position of the excess of stroke, VERICUT software has relevant prompting in system comment field, by correlation means, can be checked through program name and the position of the excess of stroke.When there is lathe in processing and frock, part produce interference, system can point out out certain axle to interfere phenomenon, and meanwhile, this axle is with red display.
