Abstract

The invention discloses a thin-wall high-position-precision hole system component machining method. Through cutting tool selection and clamping, equipment pre-running, a machining reference, machine tool precision checking, cutting amount distribution, cutting force control, component clamping and other multi-aspect technical adjustment, combination and optimization, guaranteeing of high-position-precision machining elements of components and process upgrading are achieved, and effective control over the high-position precision of the components is achieved.

Description

technical field [0001] The invention relates to a processing method of thin-walled and ultra-thin-walled hole system parts requiring high position accuracy in the field of aerospace, in particular to a method for determining and adjusting multiple factors and parameters that affect final processing accuracy. Background technique [0002] Such as figure 1 with figure 2 As shown, it is an aviation high-speed core component. In this component, the connecting flange parts made of titanium alloy require extremely high shape and position tolerances for the dimensions related to the hole system. During the first and many years of product manufacturing, conventional processing methods cannot guarantee the design requirements, and the pass rate is less than 10%. And the processing pass rate is extremely unstable, that is: in addition to the extremely high position accuracy of this series of parts and the difficult-to-cut processing characteristics of titanium alloy materials; the ...
