Advanced technologies for the calibration of machine tools are presented. Kinematic errors
independently of their causes are classified into errors within one-axis as intra-axis errors …

This paper presents an integrated geometric error modeling, identification and
compensation method for machine tools. Regarding a machine tool as a rigid multi-body …

The five-axis machine tools are increasingly popular for meeting the demand of machining
the workpiece with growing geometric complexity and high accuracy. This paper studies the …

The geometric errors of rotary axes are the fundamental errors of a five-axis machine tool.
They directly affect the machining accuracy, and require periodical measurement …

This paper proposes a product of exponential (POE) model to integrate the geometric errors
of multi-axis machine tools. Firstly, three twists are established to represent the six basic …

Five-axis CNC machine tools are widely used in manufacturing of parts with free-form
surfaces. Geometric errors of machine tools have significant effects on the quality of …

Although machine tool can meet the specifications while it is new, after a long period of
cutting operations, the abrasion of contact surfaces and deformation of structures will …

In this paper, a comprehensive error analysis method is proposed to discover how the
geometric error propagation through every motion axis, and to find out which error …

A systematic geometric model has been presented for calibration of a newly designed 5-axis
turbine blade grinding machine. This machine is designed to serve a specific purpose to …

Machining accuracy retainability is considered to be one of the most important aspects in the
process of performance evaluation and optimization design of the machine tools. Reliability …
