For the deficiencies in the prior art, the present invention proposes a kind of method of utilizing two-dimensional measurement machine testing cross section profile degree, improve the purpose that detects speed, realizes detecting and reducing online testing cost to reach.
A kind of method of utilizing two-dimensional measurement machine testing cross section profile degree, the method adopts the two-dimensional measurement machine, and is provided with grating scale at described two-dimensional measurement machine, spheric probe contact measured section, and gather the positional information of spheric probe by grating scale, may further comprise the steps:
Distance between the described measured point of step 5 is that a measurement step-length scope is 0.02mm～0.2mm.
Promotion gauge head described in the step 5 streaks tested tongue-and-groove acquisition surface measured point data with uniform dynamics, and wherein pushing direction all the time from left to right or from right to left.
Advantage of the present invention:
A kind of method of utilizing two-dimensional measurement machine testing cross section profile degree of the present invention, structure choice gauge head and measuring staff according to tested part, to reach versatility, overcome some and use the problem that the traditional optical sciagraphy can't detect such as special construction parts such as circular shape tongue-and-grooves; This measuring method can realize online while processing measuring process, detection time is short, operating process is simple.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described further.
A kind of method of utilizing two-dimensional measurement machine testing cross section profile degree, as shown in Figure 1, the method adopts the two-dimensional measurement machine, and be provided with horizontal raster chi 2 at the cross slide way 3 of described two-dimensional measurement machine, be provided with vertical grating scale 4 on the longitudinal rail 5, spheric probe 1 contact measured section, and gather the positional information of spheric probe by grating scale, in the embodiment of the invention, two-dimensional measurement machine model is SCM_0001, and grating scale is selected the open grating scale of Heidenhain brand.
Concrete steps comprise as shown in Figure 2:
In the embodiment of the invention, select the ruby spheric probe, the gauge head size is selected according to the tested position shape of tested part, and the measuring staff shape designs according to the accessibility of part.
This device is before using, with counter O reset, in the zero clearing of part reference point location, reference point institute fetch bit in the embodiment of the invention is set to the part circumference and crosses the intersection point of groove center point perpendicular to the straight line of circumference, the relative position relation of namely realizing standard component is consistent with tested part relative measurement machine positioning datum, and definite reference surface, the reference plane of the embodiment of the invention is plane, tested tongue-and-groove inside groove central point place, and gauge head is placed on reference surface and carries out zero clearing so that place on the part reference point zero point of measuring system.
The chaining pin because the tongue-and-groove SHAPE DETECTION need to be overturn, the position that the ruby ball is new has offset distance with overturn point, and the method that offset distance is determined draws according to the known groove width of measurement, size and the measuring staff base point of installation displacement numerical evaluation of ruby ball.
Wherein, come position, trigger point record by the number of counting, so just be equivalent to record according to tested step-length the data in measurement time; Described step-length scope is 0.02mm～0.2mm; Described promotion gauge head streaks tested tongue-and-groove acquisition surface measured point data with uniform dynamics, wherein pushing direction all the time from left to right or from right to left, the promotion image data of can not turning back.
In the embodiment of the invention, finish measurement after, give a two-dimensional array according to rule with the data assignment, the first row storage horizontal raster data (X-axis) of every row of its array, secondary series is deposited longitudinally (Z axis), the every row of array is exactly a some position like this.
The position of the ruby centre of sphere is to have fixing coordinate position relation with the measuring staff base point of installation, when the ruby ball contact part of gauge head, carry out data acquisition according to the shorter time interval, namely according to certain step-length, described step-length scope is 0.02mm～0.2mm, namely obtain one group of sphere center position data, calculate an actual parts point position according to per two adjacent centre of sphere data point positions, distance between this some position and two the consecutive point lines is one times of radius of a ball, and equate with above-mentioned two consecutive point distance, namely by 2 mid points and perpendicular to 2 lines, one times of radius of a ball of distance, in the embodiment of the invention concrete computation process as shown in Figure 3, the vector (X0 that the i point is ordered to i+1, Y0) after dextrorotation turn 90 degrees X1=Y0 is arranged, Y1=-X0 according to the moving direction of gauge head image data, determines that vertical component only has-90 rotations, the lateral coordinates numerical value of required piece surface equals measurement point according to the gauge head radius of one times of translation direction skew, and r is that the mould of gauge head radius is long.
