通过对某机型座舱整体骨架加工现场实测记录数据,即加工过程由于应力释放产生的零件变形的数据进行分析,采用反变形加工原理,创建含反变形工艺要求的整体骨架工艺数模,用于整体骨架数控加工。本文重点阐述了用于零件反变形加工的工艺数模设计。 Based on the measured data recorded on the whole frame of the cockpit of a certain type of aircraft, that is, the deformation of the part due to stress release in the machining process, the anti-deformation processing principle is adopted to create the integral skeleton process digital model with anti-deformation technology, The overall framework of CNC machining. This article focuses on the design of the process digital mold for the anti-deformation of parts.
