Error Distribution of a 5-Axis Measuring Machine Based on Sensitivity Analysis of Geometric Errors

Table 2

Position and position error transformation matrices of the 5-axis measuring machine (as referred to in Figure 2), where I represents the identity matrix.

Adjacent bodies	Position transformation matrix	Position error transformation matrix
0-1 (Z-axis)		I4×4
1-2 (Y-axis)
2-3 (C-axis)
3-4 (workpiece)		I4×4
0-5 (X-axis)
5-6 (B-axis)
6-7 (probe)		I4×4
