The application discloses a method for determining the quality proportion of each grade based on the maximum utilization rate of cement gobi material, and belongs to the technical field of cement stabilized base. Firstly, the aggregate with a particle size greater than the maximum screen hole of a target grading is removed from the original gobi material, and the passing rate is normalized. According to the particle size from small to large, when the normalized passing rate B a of the first determined screen hole p a is not within the range of the set upper limit and the set lower limit of the passing rate, the first grade is set. The passing rate of each screen hole is corrected. According to the particle size from small to large, when the once corrected passing rate B b of the first determined screen hole p b修正1 is not within the range of the set upper limit and the set lower limit of the passing rate, the second grade is set. The passing rate of each screen hole is corrected. The grading is continued or stopped. The quality proportion of each grade is determined. The application can quickly determine the grading screen hole size with the maximum utilization rate of gobi material and the quality proportion of each grade under the condition that the specification requirements of the mixture grading are met.

This invention provides a process method to improve the conformity problem of post-process stamping dies, including the following steps: laser-cutting the first part; determining whether the stamped drawn part meets the pass rate requirements; locking the drawing pattern on the C / H holes of the drawn part; placing the drawn part on an OP20 die; performing blue light scanning on the OP20 die; inputting the scanned point cloud into the process data, adjusting it in the Z-axis and comparing it with the process data, and performing die surface compensation based on the point cloud data; and performing secondary processing on the surface of the OP20 die.
