Function
When a defined leading axis is moved, the trailing
axes (= following axes) assigned to it traverse
through the distances described by the leading axis,
allowing for a coupling factor.
Together, the leading axis and following axis
represent coupled axes.
Applications
• Traversing of an axis by a simulated axis. The
leading axis is a simulated axis and the trailing
axis is a real axis. The real axis can thus be
traversed with allowance for the coupling factor.
• Two-sided machining with 2 combined axis pairs:
1st leading axis Y, trailing axis V
2nd leading axis Z, trailing axis W
