The chapter considers error analysis with geometric approaches. In this regard, properties of hyperspheres of different classes of distance functions are discussed. It defines different types of geometric errors using those properties for evaluating the proximity of distance functions to Euclidean metrics....
Totally 15 geometric errors, except 3 roll errors and 3 squareness errors, of the translational axes are all included in the compensation. As described in Conclusions This paper presents a systematic geometric error analysis and compensation method of 6-axis grinding machines for spiral bevel gears...
几何失真校正误差分析图像配准参数估计Circular-Scan SAR is mainly used for scene matching in the precision-guided missiles, where geometry accuracy is very important. However, due to errors introduced by the GPS/IMU, it remains somewhat geometric distortion after geometric distortion correction based on...
32, 33 worked on the geometric error analysis of a 3-DoF parallel mechanism, which is of great help in kinematic calibrations. The effectiveness of the screw theory in geometric error modeling of parallel mechanisms has been highly recognized. However, little attention has been paid to over-...

quasi-static error sources where thermal, geometric and clamping errors are included. Schmitz presents a case study for the budget analysis of the most relevant error sources in high speed milling, employing a grid plate encoder in the circle-diamond square con- touring tool path [1]. Five axi...
The results are also shown to be valid if the covariance matrix is singular. Geometric interpretations are described. 展开 关键词: PARAMETER estimation ERROR analysis (Mathematics) DOI: 10.1080/00401706.1981.10486290 被引量: 148 年份: 1981
A key step in accuracy design and error compensation is error origins analysis. The object of this study is a MCH63 Precision Horizontal Machining Center. Based on the volumetric error model and using the measurement of error origins, the effects of geometric, thermal, and cutting force-induced...
It remains, however, that an imposing number of published research and relevant machine tool standards use the term “geometric errors” for quasi-static kinematic errors. 2.1.1 Intra-axis kinematic errors Intra-axis kinematic errors [15] are also known in the literature and standards as error ...
