Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
What the present embodiment described is the process adopting the inventive method to remove wheel hub burr, and as shown in Figure 1, the inventive method comprises the steps.
Step 101, according to workpiece shapes, builds the datum plane profile of workpiece and edits its profile cut path.Fig. 2 display be datum plane profile S and the profile cut path L thereof of one of them window of wheel hub constructed by the present embodiment.
Step 102, arrangement of features sensing point on workpiece, and measure one by one.As shown in Figure 3, the straight sidewall of wheel hub window have selected eight sensing points, what point 1 to point 8 represented is the positions of eight sensing points on datum plane profile S, and point 1 ' to point 8 ' is then the actual measurement location of eight sensing points respectively.
Step 103, according to measurement data, determines the origin position of workpiece and calculates the misalignment angle of trade union college.
Step 104, with Workpiece zero point position for the profile cut path of basic point to datum plane profile rotates, the anglec of rotation is consistent with the misalignment angle of trade union college.Fig. 4 shows profile cut path L and rotates schematic diagram according to misalignment angle, and L ' is postrotational profile cut path.
Step 105, calculates the measurement data of each sensing point and the deviation of reference profile data, and analyzes the deviate of each contour machining point according to result of calculation.
