Development of a postprocessor for milling with a rotary axis and verification assisted by virtual machining environment
Апстракт
This paper presents the development of a postprocessor for a vertical milling machine with one rotary axis, commonly known as mill-turn. The subject of this analysis is the 4-axis machine MultiProDesk, whose kinematic structure formula is A'Y'OXZ. A postprocessor is a software that transforms the CL file into a machine-readable G-code. The CL file contains the universally formulated toolpath in sets of tool positions and orientations regarding the workpiece coordinate system. The inverse kinematic model method was used to derive the equations needed to transform the CL data into the displacement of the machine's axis. The displacements of the machine's axis are then implemented into a series of commands in the G-code. Machine kinematics can be designed as two unified kinematic chains with the same origin. The inverse kinematic equations were implemented in a postprocessing algorithm in the Matlab software. In order to test the derived equations, a virtual machining environment was deve...loped. The proposed kinematic model was tested using several test workpieces with different machining strategies. The virtual simulation resulted in a virtual workpiece that matched the original workpiece used to calculate the toolpath, verifying the machine's developed postprocessor.
