Background technology
The uniform cross section collimation method is complex-curved classic methods such as processing grid surface and composite surface.This method principle is simple and counting yield is higher, but it is too single to generate the track form, is difficult to adapt to the different demands of the different all kinds of trajectory plannings of shape and function.Especially when surface boundary was complex-shaped, the linear track in cross section was difficult to guarantee and the consistance on border, easily produces more short path, thereby greatly reduce the wearing and tearing that working (machining) efficiency has also been quickened cutter.For this reason, be necessary to propose the stronger job operation of adaptability.The screw type track has good operational characteristic, and machining direction changes mild, guarantees the quality of processed curved surface easily.But since its generating algorithm complexity, the processing that only is used for two-dimentional die cavity at present and has the simple surface of parameter expression.
The patent of relevant screw type numerical control processing track generation method has U.S. Patent No. 6,591,158.This patent has adopted the method for finding the solution oval boundary value partial differential equations in two-dimentional die cavity bounds to obtain the screw type machining locus.Detailed process is, at first the exterior contour with die cavity is that boundary value is found the solution Laplace's equation, obtain the isoline of series of discrete on this basis, between serial isoline, carry out smooth connection then and generate helical trajectory (smooth low-curvature spiral path).The track that adopts this method to generate is more smooth, and the direction of feed of cutter is not undergone mutation in process, has satisfied the requirement of High-speed machining preferably, but this method is only applicable to two-dimentional die cavity processing, can not be directly used in the processing of complex free curved surface, and calculate more loaded down with trivial details.Lee is at document ComputerAided Design in 2003 volume 35, in P511-518 [Contour offset approach to spiral toolpathgeneration with constant scallop height] a kind of screw type trajectory design method at the simple surface with parameter expression has been proposed, this method has guaranteed the cutter lifting number of times that cutter work in-process direction of motion one is made peace less, but relate to loaded down with trivial details ask to hand over calculate and to the offset line selfing and the judgement of handing over mutually, and exist cusp to duplicate problem, thereby make this method can not satisfy the requirement of High-speed machining effectively to high feed rate.
Summary of the invention
The objective of the invention is to invent a kind of curved surface numerical control processing method of spiral guidance.This method has overcome the defective of prior art, avoided the judgement of asking friendship calculating and selfing and mutual friendship loaded down with trivial details in the existing method, and the continuous smooth cusp that do not exist of track duplicates problem.This method is by setting up the mapping relations between the simple circular territory on complex-curved and the plane, trajectory planning is at first carried out on the planar rondure territory, by the equidistant and non-equidistant helix in the planar rondure parameter field is oppositely mapped to processed curved surface, generate machining locus, then the track of planning is done aftertreatment, generate the kinematic parameter of each correspondence of multi-axis numerical control lathe, carry out the processing of curved surface.

B. the processed curved surface with gridding is mapped on the circular domain on any given plane, and the mapping techniques of employing is linear parameterization and coordinates mapping; Set up the corresponding relation of mapping model on grid model and the circular domain thus; If the quantity of grid too much reaches more than 10,000, adopt partition map or multiresolution mapping mode;
C. determine the pitch of equidistant or non-equidistant helical: at first the center of circle with circular domain is a starting point, along the circumferential direction carry out the line-spacing test by 3 °≤α of angular range≤45 °, get the line-spacing of the minimum value of all test points as this initial circumference, and then be that radius obtains next circumference with this line-spacing, continuation is got by certain angle and is a little carried out the line-spacing test, still get the line-spacing of the line increment at test point place as this ring, the rest may be inferred, stops up to the most peripheral of circular domain;
D. the line-spacing that obtains according to step c is a starting point with the center of circle of circular domain, generate equidistant or non-equidistant helix on discrete concentrically ringed basis, when the pitch of this helix is non-when equidistant, when promptly this helix was non-linear helical, pitch can obtain apart from interpolation according to the series of rows that step c obtains;
E. the track discrete point on the snail line oppositely is mapped to the 3D grid curved surface, obtains its corresponding point on grid surface; The form that obtains of corresponding point has two kinds, and a kind of is directly to utilize the inverse mapping of coordinating mapping to obtain, and another kind is to utilize area coordinate parametrization and linear interpolation to obtain corresponding point according to the vertex information of grid;
F. the parameter of the corresponding point that will be calculated by the step e equation of bringing processed curved surface into has just obtained needed machining locus discrete point; The more rational iteration optimization of the good laggard enforcement track distribution of trajectory planning is handled.
2. according to employed numerically-controlled machine the track of planning is done aftertreatment, cutter location coordinate conversion under the workpiece coordinate system is become the translation and the rotation of each correspondence in the numerically-controlled machine coordinate system, interface by computing machine and 5 Shaft and NC Machining Test machining centers drives lathe, cutter is along the good continuous cutting movement of helix of planning, until the processing of finishing whole curved surface in the process.
Optimum efficiency of the present invention is the generative process that this new job operation has been simplified existing helical trajectory complexity greatly, guarantees that machining locus has the border consistance.Simultaneously, new method has kept continuity and the slickness before the trajectory mapping, compares with existing numerically-controlled machine machining locus (seeing accompanying drawing 7) not exist cusp to duplicate problem, has therefore improved the dynamic performance of working angles preferably, has improved working (machining) efficiency.Adopt screw type track processing curve, tool motion is steady, and machine noise is little, and tool wear is little, and it is the highest by about 30% to reduce tool wear, improves working (machining) efficiency, reaches as high as more than 50%, saves the plenty of time and reduces cost.
