Mathematical modeling method based on G codes and application

Abstract

The invention discloses a mathematical modeling method based on G codes and an application. The mathematical modeling method actually comprises the following steps: importing the G codes of numericalcontrol machining into preset software, generating a tool path by utilizing the G code, and sweeping and cutting off a blank along the tool path by a tool so as to form a three-dimensional process intermediate model consistent with an actual machining process, wherein the three-dimensional process intermediate model is a three-dimensional mathematical entity model established on the basis of mathematical Boolean differencing operation, the same G codes are used for parametric modeling and also used for machine tool production and machining, and the uniformity, uniqueness and integrity of the model are ensured by utilizing data homology.

AI Technical Summary

Problems solved by technology

Because relying on technicians to design process drawings, if the design is unreasonable, it will not only increase the processing difficulty of a single process, but also increase the processing efficiency of tooling, measuring tools, and inspection tools.

[0004] (2) A product is artificially divided into several intermediate process models, which interrupts the connection of the model in the computer and destroys the unity, uniqueness and integrity of the model. Each process can be simulated, but the entire process cannot be simulated

[0005] (3) The workload of NC programming is increased. Each process needs to establish a median size model according to the process diagram, and it is impossible to simulate the processing process for the entire product.

[0006] (4) A process file requires multiple intermediate process models, which artificially increases the workload. Due to the generation of intermediate process models, the entire workpiece processing process cannot be simulated as a whole, which is prone to errors

[0007] (5) For parts with complex structures, even if the design of the process diagram is wrong, since the process model is designed according to the product, it is necessary to manually compare and check the two models, which is labor-intensive and may not be checked out, resulting in product scrapping

[0008] (6) NC programming is located behind the process, and the process and NC programming are artificially separated. The formulation of the entire process relies on the experience and wisdom of the technicians, completely abandoning the computer, and the workload is huge.

[0009] (7) The size of the process model needs to be fully defined, because it needs to be made into a median model, which also increases the content of process inspection

[0010] To sum up, the process of preparing the entire process has become a process of designing an intermediate model based on the product model, which mainly relies on the experience accumulation of technicians. The work is difficult and labor-intensive. Since the entire production process cannot be processed and simulated, the risk increases.

At the same time, it also increases the labor intensity of NC programmers. It is necessary to establish a median model according to the process diagram, which destroys the unity, uniqueness and integrity of the model.
