The foundation shaping of part, then labyrinth part is shaped in part foundation using 3D printing technique.
The 3D printing combined shaping method greatly reduces being processed into for part while part process cycle is shortened
This.But when using this method progress part processing, there are part foundation and the matching of labyrinth part faying face to ask
Topic.In Compound Machining after foundation shaping, actual placement position and placement position during part subdivision of part have been difficult
Full weight is closed, and by manually adjusting placement position, low precision, efficiency are low, are easy to cause the knot of foundation and labyrinth part
Conjunction face is unable to accurate match, can largely effect on the forming quality of part.Therefore, it is necessary to a kind of cross-sections match method.
During the cross-sections match method applies also for 3D printing, misprint or equipment fault, which occurs, causes process
Stop suddenly, when printing again, cross-sections match when being repaired to current layer cross section.
The principle of 3D printing cross-sections match method of the present invention is, during normal print, galvanometer coordinate system acquiescence and subdivision
Coordinate system is consistent, i.e., formation of parts but is beaten with its position consistency in subdivision coordinate system in galvanometer coordinate system according to 3D
Print combined shaping method, or traditional 3D printing is broken down, when part puts printing again, then can cause part relative to
The position of galvanometer coordinate system is inconsistent in the position of subdivision coordinate system corresponding thereto.In order to ensure the accurate match of compound cross-section,
Part must be made to be consistent relative to the position of two coordinate systems.Therefore, the present invention is based on coordinate transformation method, by adjusting shaking
Mirror coordinate system or subdivision coordinate system, to ensure that part is consistent relative to the position of two coordinate systems, and then realize compound section
The accurate match in face.
Device used in the present invention is used for as shown in Figure 1, including the photographing unit 2 positioned at the top of 3D printing working chamber 1
Take pictures to shaped region 3, the computer 4 being connected with photographing unit 2 and 3D printer control system is further included, for reality
Border processing section carries out analysis matching.
It is of the invention preferably based on coordinate transform, by adjusting galvanometer coordinate system, it is consistent with subdivision coordinate system,
Ensure that part is consistent relative to the position of two coordinate systems, so as to fulfill the accurate match in section.
As shown in Fig. 2, this method specifically includes：
Step 1, according to part section in subdivision software and the relative position of subdivision coordinate system X0Y, subdivision coordinate system is determined
Positions of the X0Y in shaped region.
S1. reference marker point is printed

Printing is marked, records this 2 points coordinate (X in galvanometer coordinate system X ' 0Y 'A,YA)、(XB,YB), and counter push away galvanometer coordinate
It is X ' 0Y '.
S2. shaped region image is obtained
Taken pictures using the photographing unit at the top of working chamber to whole shaped region, obtain shaped region image,
And the image is sent to computer.
S3. section feature point is matched
Cross-sectional image in computer extraction shaping area image, chooses any two characteristic point a, b in cross-sectional area.
According to the coordinate (X of reference marker point A, B in galvanometer systemA,YA) or (XB,YB), and characteristic point a, b and reference mark
Remember the relative position of point A or B, calculate simultaneously coordinate (x of the recording feature point in galvanometer coordinate system X ' 0Y '1', y1') and (x2',
y2’)。
The seat of matching characteristic point a, b on section in subdivision software, recording feature point a, b in subdivision coordinate system X0Y
Mark (x1, y1) and (x2, y2)。
S4. the anti-position for pushing away subdivision coordinate system X0Y in shaped region
(1) position according to two characteristic points a, b in subdivision coordinate system X0Y relative to subdivision coordinate system X0Y origins, and galvanometer
Coordinate (the x of two characteristic points in coordinate system X ' 0Y '1', y1') and (x2', y2'), the anti-subdivision coordinate system X0Y origins that push away are in formation zone
Position in domain.
(2) line of two characteristic points and subdivision coordinate system X0Y reference axis in subdivision coordinate system X0Y are calculated according to formula (1)
Angle α, as shown in Figure 4.
Sat according to two characteristic point lines in subdivision coordinate system X0Y and the angle α of subdivision coordinate system X0Y reference axis, and galvanometer
Two characteristic point lines in mark system X ' 0Y ', the anti-subdivision coordinate system X0Y that pushes away is in the direction of shaped region internal coordinate axis.
Positions of the subdivision coordinate system X0Y in shaped region is obtained by step (1), (2).
Step 2, according to the relative position of galvanometer coordinate system X ' 0Y ' in shaped region and subdivision coordinate system X0Y, by that will shake
Mirror coordinate system X ' 0Y ' rotation θ angles, translationDistance, makes it be completely superposed with subdivision coordinate system X0Y in shaped region, such as schemes
Shown in 3b, 3c, to ensure that section is consistent relative to the position of two coordinate systems, the accurate match in section is completed.
In order to further ensure that the anti-accuracy pushed away of subdivision coordinate system, for the part of section complexity, in step
In rapid S3, the characteristic point of more than 3 can be chosen, after combination of two, carry out the matching of features described above point and subdivision coordinate system X0Y respectively
Counter to push away, whether consistent, if unanimously, showing if comparing positions of each group subdivision coordinate system X0Y being back-calculated to obtain in shaped region
Successful match, performs step 2；If inconsistent, show that it fails to match, re-execute step S3, S4, until successful match, then
Step 2 is performed, avoids the occurrence of matching error.
By above-mentioned steps, it is ensured that the correct matching in section, avoids the part processing caused by the problems such as dislocation and lose
Lose.
Similarly, also can be by adjusting the position of subdivision coordinate system X0Y, by galvanometer coordinate system X ' 0Y ' rotation θ angles, translationDistance, makes it be consistent with galvanometer coordinate system X ' 0Y ', so as to complete the matching in section.
