The design and kinematic modelling of a novel single-sensor three-dimensional coordinate measuring machine

2021FEBEREC-STD-042 The data attached includes: (1). The data attached includes: (1). The mirror out of squareness of the machine before and after the calibration. The mirror out of squareness deviation is the primary error of the measurement results, hence it must be established for compensation purposes. It considers the deviation/comparison with the theoretically established mirror axis. Before the calibration the ten samples were taken for x, y, and z translations and the Monte Carlo simulation was employed to generate 20 000 samples, and the standards deviation of the error/out of squareness included 0.233mm, 0.232mm, and 0.021mm respectively. However, after the calibration the standard deviation on respective axis was 0.013mm, 0.027mm, and 0.029mm. (2) Includes the measurement the repeatability of the machine and the measurement results. The machine was translated 50mm in either axis and the standard deviation was 0.047mm, 0.050mm and 0.023mm in x, y, and z axis. Further the data includes the gauge block measurements of 24mm x 24mm x 8mm in x, y and z axis, and the standard deviation was 0.012mm, 0.012mm, and 0.018mm respectively.

2021FEBEREC-STD-042 本数据集包含以下内容：(1) 机器校准前后的镜面非正方形度数据。镜面非正方形度偏差是测量结果的主要误差来源，因此必须建立以进行补偿。该偏差/比较基于理论建立的镜面轴线。在校准前，对x、y和z轴的平移进行了十个样本的采集，并采用蒙特卡洛模拟生成了20,000个样本，误差/非正方形度的标准偏差分别为0.233mm、0.232mm和0.021mm。然而，校准后，各轴的标准偏差分别降至0.013mm、0.027mm和0.029mm。(2) 包含了机器的可重复性测量及其测量结果。机器在任一轴上平移了50mm，x、y、z轴的标准偏差分别为0.047mm、0.050mm和0.023mm。此外，数据还包括了24mm x 24mm x 8mm量块的x、y和z轴测量，其标准偏差分别为0.012mm、0.012mm和0.018mm。
