The application discloses a kind of thin-walled sector structure part semicircle reference
processing method,
bushing, method includes: based on the structure of part Formulation include
heat control process
route of
shape control;Semi-finishing is carried out to part;After semi-finishing, the part is clamped using heat
shape control special fixture, heat
shape control processing is carried out, and preliminary control heat shape control after part is obtained;Finish
machining fixture is installed on lathe and is aligned;After heat shape control, the part to be machined is clamped on the aligned finish
machining fixture, and the part to be finished is fixed by aligning inner hole and applying floating support;Install
machine clamp tool and select finish
machining blade, set parameter;Semi-
circular reference plane of part is carried out finish machining
cutting, and the combined
tool path of inside-out and outside-in is used to
tool path, and
processing is completed.The application effectively controls the deformation amount before part finish machining, enhances the clamping rigidity of semicircular weak place, makes machining semicircular
reference plane positioning reliable, and improves the quality and efficiency of processing.
