The invention relates to a
programming method of a parameterized
numerical control machining program of a marine
propeller blade. The
programming method comprises the following steps: S1, translating a coordinate
system to drive a
tool path; s2, completing development of a post-
processing program in a post-
processing builder Post Builder of Siemens NX, using a TCL language as a
command language of the post-
processing builder, using an original
algorithm for a kinematic model of the
numerical control machine tool, performing parameterized assignment on a height position adjustment value of a processing
tool path in a processing program, performing
automatic translation conversion on a processing coordinate
system, and performing
automatic translation conversion on the height position adjustment value of the processing
tool path in the processing program; calculating and assigning the height adjustment value of the
machining tool path in the area between the section radiuses; and S3, a tool
machining track is generated in Siemens NX
software according to the
radius direction of the section of the blade, a post-processing program is used for being converted into a
numerical control machining program, and the section needing to be adjusted is directly modified in a parameterized machining program according to the analysis condition of the blade blank.
