Abstract

The invention discloses a method for rapidly generating a corner side milling process path, which belongs to the technical field of CAD (Computer Aided Design) / CAPP (Computer-Aided Process Planning) / CAM (Computer Aided Manufacturing). The method comprises the following steps: firstly, clicking a corner surface needing to generate a tool path in a CAM system via a mouse; automatically constructing a processing area for side milling processing of the selected corner surface; and generating corner processing process information by combining automatic generation and manual interaction according to data in a process database so as to realize rapid automatic generation of a processing area and a processing path. The method for rapidly generating the corner side milling process path has the advantages of high calculation efficiency, high flexibility and relieving of the editing workload of engineering personnel; and meanwhile, the method supports processing of a single corner and batch processing of a plurality of corners, so that different demands of engineer personnel can be met.

Description

technical field

[0001] The invention relates to the technical field of CAD / CAPP / CAM, in particular to a numerical control processing method, in particular to a method for quickly generating a machining track of corner side milling of an aircraft structural part. Background technique

[0002] Aircraft structural parts are the main load-bearing components of the aircraft, including frames, beams, wall panels and other structural types. Due to the high quality requirements and short processing cycle of aircraft structural parts, CNC machining is mainly carried out on high-end CNC machine tools. Through years of technological transformation, my country's aviation manufacturing enterprises have introduced and developed a large number of high-value, high-cost CNC machine tools and supporting equipment, but the overall utilization rate of equipment is less than 40%. One of the main reasons is the low efficiency of CNC programming. For large integral structural parts, the ratio of pr...
