1.2 Fundamentals of NC
Example:
Drawings with several relative datums
(according to ISO 129 or DIN 406, Part 11; Figure 171)
Example:
Coordinates of the point ➀ :
X = 10 mm
Y = 5 mm
Z = 0 mm
The datum of the Cartesian coordinate system is located 10 mm away
from point ➀
on the X axis and 5 mm on the Y axis.
The 3D Touch Probe System from HEIDENHAIN is an especially conven-
ient and efficient way to find and set datums.
