The tool is raised again and taken into the new resetting
position for the X axis. With the spindle switched
on it is moved along the side surface of the work part
(Y, Z plane) in the X direction (see figure 53) until a
small marking is made on the work part surface
(touching the work part).
When touching the work part in X axis the radius of
the applied tool has to be considered when confirming
the value with the IST key, since the center point
coordinates of the tool are always used in NC programming.
If the milling tool of the adjacent figure has, for instance,
a radius of 15 mm, then the value X=-15 is
entered into the NC control and confirmed with IST.
