Developing a postprocessor for three types of five-axis machine tools

Abstract

This paper presents a postprocessor capable of converting cutter location (CL) dam to machine control data for three typical five-axis machine tools to establish an interface between computer-aided manufacturing (CAM) systems and numerically controlled (NC) machines, The analytical equations for NC data are obtained using the homogeneous coordinate transformation matrix and inverse kinematics. In addition, the developed postprocessor method is implemenwd through a trial-cut on a five-axis machine and verified on the coordinate measurement machine. Experimental results confirmed the effectiveness of the proposed postprocessor method which can be used to integrate the various five-axis machine tools employed in manufacturing systems.

Analysis of Nonlinear Error Caused by Motions of Rotation Axes for Five-Axis Machine Tools with Orthogonal Configuration

“…In machining, the primary rotation axis has a fixed spatial direction, while the secondary axis moves, and the position of the secondary axis varies with the motion of the primary rotation axis. Therefore, for the RT-type machine, the relationship between the tool orientation V i in WCS (work coordinate system) and rotation angles in MCS(machine coordinate system) can be expressed as [13] …”

“…Jung et al [12] built a postprocessor that is suitable for the RT-type five-axis machine tool. Lee et al [13] developed analytical equations capable of converting cutter location (CL) data and tool orientation vectors into machine control coordinates for the three representative types mentioned above. Several approaches have been proposed for building generic kinematic models that are applicable to all five-axis machine tool structures [14][15][16][17][18][19].…”

Kinematic modeling of 5-axis horizontal milling machine emulated from vertical articulated robot

“…A specialized 5-axis machining robot, Figure 2b, unlike the standardized one, has a specific arrangement of orientation axes so that it emulates a 5-axis vertical machine tool. Such emulated 5-axis machine tools belong to the class of machine tools in which tool orientation is realized by its rotations [11,12]. In this paper, emulation of standardized and specialized 5-axis robots, i.e.…”

Development of multifunctional reconfigurable desktop machine tool with hybrid kinematics

“…Programiranje mašina sa serijskom kinematikom tipa WCBVXYZT u nekom CAD/CAM okruženju je rutinsko, kada se pripremi dobar postprocesor [6]. Međutim, postprocesor za mašine sa paralelnom i hibridnom kinematikom nisu uobičajeni.…”
