The application provides a circular arc end tooth
rounding and chamfering
processing method and
system, and relates to the technical field of
machining. The method comprises the following steps: installing a high-precision measuring head on a five-axis
numerical control machining center, planning a outer circle, inner circle and tooth end
surface measurement program according to an end tooth
solid model by using
adaptive software QJCAM, obtaining point position data through contact measurement, leveling and aligning the end tooth and determining the angular position according to the point position data, and updating the
machining coordinate
system; after the part position is calibrated, QJCAM generates a
rounding contact surface feature program, plans a measurement path based on the new coordinate
system, analyzes the results after running, and fits the end tooth model of the actual size according to the returned data through a specific
algorithm; QJCAM maps the original
tool path to the new model, adaptively adjusts and generates a new
tool path according to the model geometric characteristics and the accuracy requirements, accurately controls the five-axis machining path, realizes high-precision, high-efficiency and intelligent
rounding and chamfering machining, and ensures the smoothness and accuracy of the
tool path. The application realizes efficient and intelligent machining, and is suitable for machining of key components such as aircraft engines.
