Collision Detection and Analysis Method for Gantry Hole-making Machine Tool Machining

Abstract

The invention provides a gantry hole making machine tool machining collision detection analysis method. In the gantry hole making machine tool machining collision detection analysis method, the workpiece curve surface and the clamp of a fixed workpiece are subjected to discrete processing to obtain discrete point cloud data, the sub-machine-tool of a gantry hole making machine tool is subjected to modeling to obtain a first key parameter set (as shown in the description) and a second key parameter set (as shown in the description) of the sub-machine-tool, a point cloud set of a theoretical processing hole for collision determination is further selected, and whether the points in the point cloud set collide with the sub-machine-tool of the theoretical processing hole is determined, all of the theoretical processing holes of the workpiece are subjected to the above determination, so that the machinability analysis of all of the theoretical processing holes of the workpiece can be completed, and the subsequent actual hole making can be facilitated.

Description

Technical field [0001] The invention relates to the field of aviation digital manufacturing, in particular to a collision detection and analysis method for gantry hole making machine tools. Background technique [0002] Hole making task is a very important task in aviation hole making, and it occupies a large proportion of operations in aircraft manufacturing and production. The current processing method mainly adopts manual hole making method, which uses manual scoring and then uses manual electric drill to complete the hole making operation. In the manual hole making, the quality of hole making depends on the technical proficiency of the workers, it is difficult to guarantee the same quality, and serious hole making problems such as group hole out of tolerance may occur. The hole-making parts are aircraft wings or fuselage frame beams and skins, which have been installed and fixed in multiple processes in the early stage, and the manufacturing cost is expensive. For aviation pr...

Problems solved by technology

In artificial hole making, the quality of hole making depends on the technical proficiency of workers, it is difficult to guarantee consistent quality, and serious hole making problems such as out-of-tolerance groups of holes may occur

The hole-making parts are aircraft wings or fuselage frame beams and skins. They have been installed and fixed in multiple processes in the early stage, and the manufacturing cost is expensive. For aviation products with special requirements, the processing accuracy is higher.
