3.1.8 Axis synchronization
3.1.8 Axis synchronization
The “axis synchronization” function is an ordering data
option.
The “axis synchronization” function duplicates the programmable main axis as long as the
maximum permissible number of axes is not exceeded (for 810T/M and 820T/M, five axes).
With this function two identical workpieces can be produced by one machine tool with two tool
systems by a part program running in a channel of the NC.
The “axis synchronization” function is only available in “AUTOMATIC” and “MDI AUTOMA-
TIC” modes and in “AUTOMATIC interrupted”. For axis synchronization a measuring circuit is
available for every axes including the following axis. Therefore, two pairs of axes can be
synchronized. The fifth axis remains for use as an independent axis.
The “axis synchronization” function is modal, i.e. it remains active, until a RESET is performed
using the RESET key or until a mode change with an implicit RESET is initiated (for further
details see Section 2.3.4 “RESET with change of operating mode”).
Example:
If the part program is interrupted in “AUTOMATIC mode”, an axis pair can still be traversed
simultaneously after a change to “JOG” or “INC” (leading and following axis).
Reason: This mode change does not cause a “RESET”. The “axis synchronization” function
remains active.
3.1.8.1 Function of the modes with “axis synchronization”
“PRESET” AND “REFPOINT” modes:
The axes of tool system 1 and tool system 2 must be selected separately using the traverse
keys as in the modes without “axis synchronization”.
“JOG”, “REPOS”, “INC” without “AUTOMATIC interrupted” or “Block search”:
The axes of the two tool systems can only be moved separately.
“JOG”, “REPOS”, “INC” after “AUTOMATIC interrupted” or “Block search”:
In these modes the offsets which have arisen between the leading and the following axis after
“Block search” or “AUTOMATIC interrupted” etc. can be eliminated in various ways:
