Description
Technical field
The present invention relates to multiaxis NC maching field, specifically five axis holes process universal post processing method.
Background technique
With the fast development of numerical control processing industry, 5-shaft linkage numerical control processing technology is widely used to aerospace,
Shipbuilding, automobile, in the processing of the high-accuracy complex parts of the industry such as energy.Five-axis linkage machine tools are compared to three axis and four axis machines
Bed, increases two rotary shafts, so that cutter axis orientation is more flexible, cutter shaft theoretically may be implemented and process at any angle.However,
The Path source file of CAM Software Create can not directly drive numerically-controlled machine tool.
Postpositive disposal is exactly that cutter location file is converted into machine tool numerical control system to identify and correctly drive machine tool motion
The treatment process of NC code.General postpositive disposal, such as a kind of patent " universal post processing method for multi-axis numerical control machine tool (Shen

Postpositive disposal towards specific lathe, machine tool structure is different, and required postpositive disposal is different, and versatility is poor；2, hole cannot be generated
Fabrication cycles numerical control program, to can not achieve in functions such as bottom hole stop, the settings of bore hole withdrawing.
Summary of the invention
For the deficiency of existing universal post processing method, the present invention proposes a kind of five axis holes processing general postprocessing
Method, the mode that the hole machined mode of five-axle linkage is changed into five axis orientation and recycled using hole machined.Five-axle linkage hole adds
Work postpositive disposal principle are as follows: the information for handling each point in order calculates corresponding lathe knot by the unit vector of point
The rotary shaft amount of spin of structure, then calculate postrotational displacement compensation amount and be superimposed with former coordinate value, to obtain three position ginsengs
Several and two angle parameters.Five axis orient hole machined postpositive disposal principle are as follows: establish master coordinate system and subcoordinate system, master coordinate system
For Cutter coordinate system, master coordinate system is rotated with Eulerian angles XYZ sequence then, keeps Z axis parallel with hole point unit vector, thus
Subcoordinate system is obtained, and calculates three rotation angle parameters, the i.e. relationship of master coordinate system and subcoordinate system, recycles hole point
Under main Cutter coordinate system coordinate value and the calculating of three rotation angle parameters portal coordinate of the point under sub- Cutter coordinate system
Value.The drilling loop parameter in cutter location file is then demultiplex out, so that whole parameter required for five axis orientation hole machined is obtained,
Complete postposition treatment process.The present invention provides a kind of general five axis hole for being suitable for various machine tool structures and system for technologist
Postposition method is processed, the artificial link for calculating angle is reduced, is conducive to improve numerical control programming accuracy and efficiency.
The technical solution of the present invention is as follows:
A kind of five axis hole processes universal post processing method, it is characterised in that: the following steps are included:
Step 1: reading cutter location file；
Step 2: hole machined operation is judged whether it is, if so, next step is transferred to, if it is not, using universal post
Processing handles this section of cutter location file；
Step 3: judging whether cutter shaft changes, if there is a change, go to step 4, if do not changed, go to
Step 6；
Step 4, using generating tool axis vector, calculate Eulerian angles；
Step 5, output inclined surface circulation, the Eulerian angles that step 4 is calculated are recycled as parameter assignment to inclined surface；
Step 6, the coordinate value X, Y, Z for calculating subcoordinate system lower opening site；
Step 7, delivery outlet fabrication cycles program, using the calculated Z value of step 6 as hole machined initial surface parameter assignment
It is recycled to hole machined；
Step 8, the output calculated X of step 6, Y value, and hole machined is called to recycle；
Step 9 judges whether hole circulation terminates, if so, step 10 is gone to, if not, repeating step 3~step 9；
Step 10 judges whether it is last knife position, if so, step 11 is gone to, if not, going to step 2；
Step 11, EP (end of program).
Beneficial effect
The present invention provides a kind of postpositive disposal method specifically for the processing of five axis holes, and five-axle linkage hole machined mode is turned
Turn to five axis directional hole processing methods.It can be with two disadvantages of effective solution five-axle linkage hole machined processing mode.1, major
Lathe manufacturer, although machine tool structure is different, digital control system is different, is provided which five unified axis oriented machining schemes, wherein
Most widely used is Eulerian angles inclined surface fabrication cycles.Therefore method provided by the invention has stronger versatility.2, five
