Estimate blade qualification, vice versa.
According to the definition of profile tolerance in ISO, the definition of profile tolerance of the present invention is blade eyeball and rule blade to be assessed
The sum of highest vertical range and minimum vertical range between profile.Blade to be assessed is drawn out on rule blade profile diagram
After profile, manual identified goes out between the suspicious maximum spacing and minimum between the point on blade to be assessed and rule blade profile
Away from, it is then calculated using CAD, calculates the actual profile degree of blade to be assessed, and it is compared with predetermined value, assessment blade
It is whether qualified.
The present invention is embodied as each section and creates a figure layer, then pours into three-dimensional coordinates measurement result with the likeness in form of curve
Into CAD because after three coordinate measurement blades it is getable be X, Y, Z numerical value for depositing each point hereof, as soon as possible with
The likeness in form of curve is input in CAD.As long as reducing the subsequent operation requirement of inspector, input order can be by three in AutoCAD
Coordinate crop leaf measuring data graphing is into AutoCAD.
When operating in the prior art using autolisp, blade or rule blade blade profile to be assessed is analyzed in CAD
It after total points in always points, number of cross-sections and each section of parameter, needs manually to be input in CAD, so that CAD draws bid
The profile of quasi- blade or blade to be assessed, the blade profile that then CAD is drawn out at this time are pline linear as shown in figure 3, i.e. one
Secondary line transect, the blade profile that multiple line segments are formed, is not smooth line segment, and calculating profile error value is relatively difficult, also
Needing that the linear blade profile of pline is manually converted to the linear blade profile of spline using pedit just can be carried out
It compares, spline linear is quadratic spline line, and all line segments in each section of artificial selection is also needed to carry out during conversion
It converts one by one, it is time-consuming and laborious, working strength is considerably increased, and by means of the present invention, it is direct using the VBA program of CAD
The linear blade profile of spline is generated as shown in Fig. 2, the working time is greatly saved, improves efficiency.
