Introduction
Fig. 1.14:
Point
➀
defines the coordinate
system
Example:
Drawing with several relative datums
(ISO 129 or DIN 406 Part 11, fig. 171)
Example:
Coordinates of point
➀
:
X = 10 mm
Y = 5 mm
Z = 0 mm
The datum of the Cartesian coordinate system is located 10 mm from
point
➀
on the X axis and 5 mm from it on the Y axis.
The 3D Touch Probe System from HEIDENHAIN is an especially
convenient and efficient way to find and set datums.
