- Coordinate conversion using an Euler's angle
Coordinate conversion by rotation is assumed to be performed around the workpiece
coordinate system origin.
Let the coordinate system obtained by rotating the workpiece coordinate system
around the Z-axis by an angle of α degrees be coordinate system 1. Similarly, let
the coordinate system obtained by rotating coordinate system 1 around the X-axis by
an angle of β be coordinate system 2. The feature coordinate system is the
coordinate system obtained by shifting the coordinate system that is obtained by
rotating coordinate system 2 around the Z-axis through an angle of γ degrees from
the workpiece coordinate system origin by (Xo, Yo, Zo).
Fig.3 (e) shows the relationship between the workpiece coordinate system and the
feature coordinate system.
The figure also gives examples of displacement on the X-Y plane.
