1 FLEXIBLE SYNCHRONOUS CONTROL
1.1 General
This function is provided for machines that require synchronizing two
or more different gear ratios, such as a hobbing machine.
The function can simultaneously place up to four sets in
synchronization independently. For example, it is possible to realize
special hobbing machine functions, such as synchronization between
a hob axis and one workpiece axis, Z-C synchronization in helical
gear cutting, and Y-C synchronization in hob axis shifting.
The specification of flexible synchronous control is as follows:
1) Master and slave axis numbers, and gear ratios are set in
parameters.
2) These parameters are divided into four groups. So, four
synchronization operations can be performed simultaneously.
3) The same slave axis can be specified for more than one master
axis.
4) Synchronization is started and canceled by DI signals received
from the PMC.
However, switching DI signals during an automatic operation
requires using M codes specified in parameters.
5) Two Cs axes can be used as master and slave axes.
6) Retraction is possible in the same manner as for hob functions
(M-Series) and general purpose retract function.
7) Using feedback pulses for the spindle that runs on the Cs axis
supports feed per revolution.
(Only for M-Series)
The command format is
G95 P_; where P_ is the Cs axis number.
Feed per minute function is included in the threading /
synchronized feed option.
