Abstract:

Ever-increasing demand for complex freeform surfaces machined by ultra-precision five-axis machines necessitates efficient on-machine surface measurement (OMSM) systems. While OMSM offers significant advantages in metrology efficiency and machining accuracy, integrating it with these machines presents a challenge due to complex data synchronization and processing. This paper addresses this challenge by proposing a dedicated controller for synchronized acquisition of sensor measurement data and machine coordinate data. Additionally, a straightforward sensor alignment method is presented. The ef

Abstract:

In this study, the contouring control problem of a five-axis machine tool was examined. Due to the rotation axes, there are two coordinate systems involved in the five-axis machine tool, namely the workpiece coordinate system and machine coordinate system. The five-axis machine tool is required to follow a given desired path with tool orientation specified in the workpiece coordinate system. However, the system dynamics of the machine tool is described in the machine coordinates. Kinematic transformations exist between the two coordinate systems.

Abstract:

During large-size gear topological modification by form grinding, the helical gear tooth surface geometrical shape will be complex and it is difficult for the traditional scanning measurement to characterize the whole tooth surface. Therefore, in order to characterize the actual tooth surfaces, an on-machine topography measurement approach is proposed for topological modification helical gears on the five-axis CNC gear form grinding machine that can measure the modified gear tooth deviations on the machine immediately after grinding. Combined with gear form grinding kinematics principles, the

Abstract:

Five-axis machining, an important processes in precision manufacturing, has been used in defense, aerospace and consumer product industries. Many combinations can be synthesized to generate various five-axis machine tool configurations, in which the linear and rotary axes are normally orthogonal. Since five-axis NC data can only be applied to a specific configuration, the portability of the NC data is inevitably limited. A special purpose five-axis machine with a nonorthogonal linear axis configuration is investigated in this research. The complete analytical equations for NC data are obtained

Abstract:

Position Independent Geometric Errors (PIGEs) of rotary axes, which are caused by imperfections during assembly of machine tools, are proved to be a major error source of a five-axis machine tool. In this paper, a PIGEs characterisation method using a Double Ball Bar (DBB) is proposed. The method is used to characterise the PIGEs based on the coordinated motion involving linear and rotary axes of a five-axis machine tool. Based on the machine tool kinematic topological structure and the screw theory, the comprehensive error model of the machine tool is established and the decoupling of PIGEs i

In this paper, a fiducial-aided reconfigurable artefact is presented for estimating volumetric errors of multi-axis machine tools. The artefact makes use of an adjustable number of standard balls as fiducials to build a 3D artefact which has been calibrated on a coordinate measuring machine (CMM). This 3D artefact demonstrates its reconfigurability in its number of fiducials and their locations according to the characteristics of workpieces and machine tools.

Abstract Classification of galaxy morphology is a challenging but meaningful task for the enormous amount of data produced by the next-generation telescope. By introducing the adaptive polar-coordinate transformation, we develop a rotationally-invariant supervised machine-learning (SML) method that ensures consistent classifications when rotating galaxy images, which is always required to be satisfied physically, but difficult to achieve algorithmically.
