8. SAFETY ZONE CHECK
Set the machine coordinate value when the workpiece holder is positioned
at the tool center (punching position), in the parameters 16505 – 16516
in output units.
X2a X1a X2b X1b X2c X1c X2d X1d
Origin of work coordinate system
Regarding #1 in Fig. 8.3, the safety zone is specified at both ends (X1a,
X2a) for the X–axis direction, and at the forward end (Ya) of the
workpiece holder for the Y–axis direction. The specifying method is the
same as for #2, #3 and #4.
Considering the setting value in the work coordinate system, it is the value
obtained by subtracting the set value of automatic coordinate system from
the workpiece holder position in the work coordinate system.
For example, set value of X2a is as follows in Fig. 8.3.
Set value (X2a) = (H1wz) – (Xwz)
Set four safety zones to be arranged sequentially in the order of #1, #2,
#3 and #4 from the origin to positive of the X–axis.
