Along with the progress of science and technology, the structure of blade becomes increasingly complex, and the special formed all available slots on blade define, and carry out numerical control programming by the job operation of groove.The RCS software that this reaches the exploitation of glug Hai Kete (StarragHeckert) company by Switzerland is the five-shaft numerical control machining prgraming software being exclusively used in blade, its NC Machining Program instrument be made up of multiple module software bag, the data model of this software is blade, hole and groove etc., and adopt UGtoRCS instrument can directly derive blade profile from UG model, blade root, integral shroud and groove geometry data file are used for RCS software and carry out numerical control programming, although the RCSutil instrument that RCS software carries can to blade profile, blade root, the geometric data of integral shroud carries out mirror image, but it cannot directly revise groove geometry data, thus batch mirror image cannot be carried out to the geometric data of groove.Two kinds: one is had to be by after leaf model mirror image in UG to the mirror method of groove at present, the groove geometry data after mirror image is directly read again with UGtoRCS instrument, but read groove geometry data with UGtoRCS instrument can only read one by one successively, when the groove geometry data amount of blade is huge, its reading speed is slow, affects numerical control programming speed; Two is directly carry out manual modification fluting geometry data by the RCS programming file of blade, it cannot carry out batch mirror image to groove, and in RCS programming, because the data layout of groove is by the curve be made up of multi-section-line, straight line, circular arc and SlotUG Four types, the specific characteristic of blade is more, and groove is more, if the geometric data of manual modification groove and machined parameters one by one, the time and efforts then spent is more, easily makes mistakes, and affects program speed; And the method cannot carry out manual modification to the groove geometry data read with UGtoRCS instrument.
Summary of the invention
For the problems referred to above, the invention provides a kind of method of the batch mirror image groove based on RCS, it can solve the existing problem to cannot carry out batch mirror image in the mirror method of groove to groove, thus effectively improves speed and the accuracy of the mirror image processing of groove.
Based on a method for the batch mirror image groove of RCS, it is characterized in that: it comprises the following steps
Step 1, establishes five-axis robot coordinate system RCS coordinate system, and described RCS coordinate system and UG coordinate system is consistent, and the RCS geometry data of typing blade groove forward or backwards also determines the groove geometry data needing to carry out mirror image operation wherein;
Step 2, read the current groove geometry data needing to carry out mirror image operation, judge whether this current type needing to carry out the groove geometry data of mirror image operation is the SlotUG formatted file read by UGtoRCS instrument, if this current groove geometry data of carrying out mirror image operation that needs is the SlotUG formatted file read by UGtoRCS instrument, directly mirror image processing is carried out to this current data obtains mirror image data and described mirror image data is preserved with the form of intermediate file, otherwise enter step 3;
Step 3, judge that current needs carry out the data layout of the groove geometry data of batch mirror image operation, and judge groove geometry data type according to described data layout, described groove geometry data type comprises curve type, line-type and circular arc type;
According to step 3, step 4, judges that the described groove geometry data type obtained is carried out mirror image processing to this current data respectively and obtained the mirror image data of corresponding data type and preserved with the form of intermediate file by this mirror image data;
Step 5, deletes the groove geometry data that former needs carry out batch mirror image operation, and the intermediate file of described mirror image data is saved as groove geometry data; Carry out next again to treat mirror image processing to need the groove geometry data mirror image processing of carrying out mirror image operation complete until all.
Beneficial effect of the present invention is: its data layout carrying out the groove geometry data of mirror image processing is as required to judge the type of groove, and respectively corresponding mirror image processing is carried out to groove geometry data according to the type of groove, therefore batch mirror image processing can be carried out to the groove geometry data of complexity, greatly improve speed and the accuracy of groove mirror image processing, thus effectively improve the speed of blade digital control programming, increase work efficiency.
