Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as Figure 1-3 shown.

[0039] An integrated CNC machining capability test model for aircraft structural parts. It is a double-sided part. One side has different web heights and different rib top heights. It is defined as the front side, and the other side has the same web height and rib top height. for the negative side. Its overall structure is similar to an n-shape, with a c-shaped notch running through the front and back, and the front is provided with multi-layer grooves 2 including convex platforms, convex depressions, concave depressions, intersecting independent ribs and open ribs, The two sides of the multi-layer groove 2 are respectively adjacent to the multi-layer groove 1 and the multi-layer groove 3 with intersecting characteristics of nesting, and the other side of the multi-layer groove 2 opposite to the outer contour is res...

Abstract

The invention discloses an integrated airplane structural part numerical-control machining capacity test model and the application thereof. The integrated airplane structural part numerical-control machining capacity test model is characterized in that the model is a double-sided part and includes airplane structural part typical machining characteristics and syntagmatic relation thereof, the machining characteristics include typical grooves, ribs, holes and outlines and the like and comprise intersection features, opening and closing angles and free-form surfaces, and the characteristics include typical dimensions such as web thickness, web area, difference of groove layers of a multi-layer groove, rib thickness, rig height and turning angle radius. Using the model can test efficiency and accuracy of general CAD (computer-aided design) / CAM (computer-aided manufacturing) software and special automatic programming systems and can further test airplane structural part machining capacity of numerical-control machine tools and airplane structural part machining technological levels, detection process, working hour predication and the like of numerical-control machining factories.

Description

technical field [0001] The invention relates to a numerically controlled machining test model of aircraft structural parts, in particular to a CAD (Computer Aided Design) / CAPP (Computer Aided Process Planning) / CAM (Computer Aided Process Planning) / CAM (Computer Auxiliary processing) software performance test model, specifically an integrated aircraft structural parts CNC machining capability test model and its application. Background technique [0002] Aircraft structural parts are an important part of the aircraft body skeleton and aerodynamic shape, mainly including frames, beams, ribs and other types. The use of the overall structural parts of the aircraft greatly reduces the number of aircraft body parts, reduces the assembly workload, and significantly improves the manufacturing quality of the aircraft. The structure of aircraft structural parts is complex, with many processing features, including a large number of free-form surfaces, intersecting features and special ...
