Abstract

The invention, which belongs to the technical field of a tool post-processing method of a five-axis numerical control machine, discloses a universal post-processing method for a five-axis numerical control tool grinding machine so that a problem that the existing post-processing method of the machine tool is not suitable for the five-axis numerical control grinding machine because of not considering the initial axial direction of the grinding wheel and the mounting positions and mounting directions of multiple grinding wheels and inconsistency of the workpiece coordinate system direction and the machine tool coordinate system can be solved. The method comprises: establishing a unified coordinate system; setting characteristic parameters of a grinding machine; establishing a universal grinding machine post solution equation; and calculating the equation established at the previous step by using a method based on grinding machine type transformation. According to the invention, a novel method is provided for post processing of a five-axis numerical control grinding machine; and the post-processing method can be applied to existing 36 kinds of five-axis numerical control grinding machines on the market and has high universality.

Description

technical field [0001] The invention belongs to the technical field of post-processing methods for five-axis numerically controlled machine tools, and in particular relates to a general post-processing method for five-axis numerically controlled tool grinders. Background technique [0002] The five-axis linkage tool grinder is an important machine tool for processing complex-shaped tools. Its post-processing process needs to convert the tool position files generated by the tool design software into corresponding numerical control codes according to the specific structure of the grinding machine, which is an important link in the tool grinding process. [0003] The existing five-axis machine tool post-processing research is mainly aimed at the classification of machine tool structure and solving the mathematical model of motion. Among them, the research on machine tool classification is mainly based on the distribution of motion axes to classify machine tools into three catego...
