Abstract
A fiveaxis machine can be developed with various mechanisms as it simply adds two axes to three coordinate axes Therefore fiveaxis machining utilizes postprocessor for conversion to NC code which the fiveaxis machine can read with tool path CL data created by CAM depending on the mechanism of each device This study introduces a postprocessor program that tilts from axis B of which the head is inclined at about 45 degrees moves straight toward the X and Z axes rotates the table from C and then moves along axis Y The postprocessor mechanism was applied to the program after calculating the rotation angles and tilting angles using inverse kinematics and mapping the part coordinate system by machine coordinate system Then to evaluate the established post processor formula it was verified twice First a tool path that was identical to that created by a commercial postprocessor program Post Works was postprocessed and comparably reviewed to verify the performance of the proposed method Secondly a test specimen was manufactured by creating NC data from the developed post processor program After manufacturing the test specimen the compatibility was verified suggesting the possibility to commercialize the fiveaxis machine and the postprocessor program
