Background technology
Surface waviness is that spacing is more than surface roughness but is less than the surface geometry unevenness of morphology error,
Belong to the microcosmic geometric error between macroscopic view.
Aero-engine compressor rotor blade visually inspects blade percent ripple, blade one using master body mostly at present
As last 0.05-0.3mm surpluses are removed to reach the final requirement of design using hand polish after digital control processing, removed in polishing
Easily blade profile profile is caused to damage during surplus, be affected by operator's level of skill, and then influence blade ripple
Line degree；When detecting percent ripple, by master body, visual comparison checks, larger by man's activity, is also easy to produce error in judgement, shadow
Ring product quality.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of compressor rotor blade blade percent ripple processing technology and
Detection method.
The present invention is achieved by the following technical programs.
A kind of compressor rotor blade blade percent ripple processing technology provided by the invention, step are：
1) numerical control modeling is carried out using software；
2) local optimum processing is carried out to CNC Model；
3) numerical control program is worked out；
4) it is processed using the numerical control program worked out；
5) finishing blade only carries out surface finishing when polishing blade using polishing machine, improve surface roughness.
It is with segmentation, conversion, mobile, rotation, connection, light that CNC Model, which carries out local optimum processing, in the step 2)
At least one of suitable operation is completed.
Numerical programming program imports postpositive disposal software by CNC Model first in the step 3).
The postpositive disposal software is TS8.5.
The tooling step of the numerical control program includes trimming, thick back chipping, milling blade, milling listrium, seminal plasma root.
The software used that models is UG.
The polishing appliance that the polishing machine uses is fine wool felt wheel.
A kind of detection method of compressor rotor blade blade percent ripple, method comprise the following steps：
1) BLADERUNNER Blade measurings：By the blade profile data of MBLADEMESURE software scans, through BLADERUNNER
The molded line of percent ripple is formed after processing, is sent into Blade softwares；
2) PCDIMS software corrections:Part coordinate system is established using " 3-2-1 " method, process of measurement is measured using software generic
Program is finely adjusted amendment to measuring tool interference position；
3) BLADE Blade measurings data analysis：The gross data of measurement model is imported into software, is exported in a graphical form
The measurement report of molded line profile tolerance.
The beneficial effects of the present invention are：The equipment advantage of five-axis NC machine center is made full use of, accurately controls blade
Surplus, carries out no surplus processing, and polishing need not remove surplus, only carry out surface finishing to blade, both can more fully protect
The profile tolerance and percent ripple that five-shaft numerical control is stayed to process improve product quality and homogeneity of product, and buffer can be greatly decreased
The workload of sequence；Simultaneously using three-dimensional coordinates measurement machine testing percent ripple, testing result precisely can be objectively fed back, need not be led to
It crosses master body and carries out visual comparison, greatly reduce influence of the human factor to measurement result.
Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of compressor rotor blade blade percent ripple processing technology, step are：
1) numerical control modeling is carried out using software；
2) local optimum processing is carried out to CNC Model；
3) numerical control program is worked out；
4) it is processed using the numerical control program worked out；
5) finishing blade only carries out surface finishing when polishing blade using polishing machine, improve surface roughness.
It is with segmentation, conversion, mobile, rotation, connection, light that CNC Model, which carries out local optimum processing, in the step 2)
At least one of suitable operation is completed.
Numerical programming program imports postpositive disposal software by CNC Model first in the step 3).
The postpositive disposal software is TS8.5.
The tooling step of the numerical control program includes trimming, thick back chipping, milling blade, milling listrium, seminal plasma root.
The software used that models is UG.
The polishing appliance that the polishing machine uses is fine wool felt wheel.
A kind of detection method of compressor rotor blade blade percent ripple, method comprise the following steps：
1) BLADE Blade measurings Data Analysis Software：The gross data of measurement model is imported into software, according to design requirement
Tolerance file and algorithm file etc. are set
2) PCDIMS softwares:It requires to establish part using " 3-2-1 " method (face, line, point " method) according to actual measurement system and sit
Mark system, key step have centering (determining first axis), rotate to axis (determine second axial), translation (determines three axial directions
Zero point)；Process of measurement uses software generic process of measurement, and amendment is finely adjusted to measuring tool interference position.
3) BLADERUNNER Blade measurings software：BLADERUNNER is the special leaf supported under PCDMIS measuring systems
Piece machined surface profile Survey Software.The measurement of blade percent ripple can be thought of as it to be that blade profile gets up to measure vertically, then just
