Problems solved by technology

Using general post-processing, CAM software can only generate five-axis linkage hole machining NC programs. This processing method has two disadvantages: 1. Five-axis linkage is post-processing for specific machine tools. The structure of machine tools is different, and the required The post-processing is different, and the versatility is poor; 2. The hole machining cycle NC program cannot be generated, so that functions such as staying at the bottom of the hole and setting the boring retract tool cannot be realized.

Abstract

The invention provides a five-axis hole machining post-processing method especially for five-axis hole machining. A five-axis cooperation hole machining mode is converted into a five-axis directional hole machining mode. Two disadvantages of the five-axis cooperation hole machining processing mode can be effectively solved. 1, All the big machine tool manufacturers have different machine tool structures and different numerical control systems and provide a unified five-axis directional machining scheme in which the widely used is the Euler angle inclined plane machining cycle so that the method has high generality; and 2, the hole machining cycle can be used in the five-axis directional machining mode so that the hole machining functions of staying at the bottom of the hole and boring retracting setting can be realized, and thus the method has important meaning.

Description

technical field [0001] The invention relates to the field of multi-axis numerical control machining, in particular to a general post-processing method for five-axis hole machining. Background technique [0002] With the rapid development of the CNC machining industry, five-axis linkage CNC machining technology has been widely used in the processing of high-precision and complex parts in aerospace, shipbuilding, automobile, energy and other industries. Compared with the three-axis and four-axis machine tools, the five-axis machine tool adds two rotation axes, which makes the direction of the tool axis more flexible, and can theoretically realize machining at any angle of the tool axis. However, the source file of tool position trajectory generated by CAM software cannot directly drive the CNC machine tool. [0003] Post-processing is the process of converting tool position files into NC codes that can be recognized by the CNC system of the machine tool and correctly drive th...
