Abstract

The invention provides a method of product process programming simulation for intelligent manufacturing of aeronautical machined products. The method constructs the whole process of intelligent manufacturing of machined products, including the definition of design features and modeling of specification standards, and the realization of automatic programming of process features driven. The method establishes a collaborative process simulation and inspection platform, realizes the connection and transmission between the process simulation platform and the standard libraries, constructs the programming feature library and operation library suitable for intelligent NC programming, establishes the NC programming standard integration method for intelligent manufacturing, realizes the NC programautomatic programming and simulation operation environment driven by machining features, and then establishes the omni-directional intelligent manufacturing.

Description

Technical field [0001] The invention forms a set of intelligent manufacturing-oriented product process programming simulation methods for aircraft accessories, and belongs to the field of aircraft manufacturing. Background technique [0002] Because airplanes have higher requirements for reliability, comfort and economy, and are also under the pressure of on-time delivery of batch airplane orders, it will be difficult to adapt to the development and production characteristics of airplanes and customer needs simply by following the existing airplane manufacturing technology system , It is urgent to adopt more advanced and applicable manufacturing technology and information technology to improve the manufacturing capacity and level of civil aircraft. Especially for various aircraft structural parts that are mainly CNC machining, they account for more than 75% of all aircraft parts processing and manufacturing workloads. In addition, there are many types, large quantities, complex s...
