Case 1： The actual cam relationship is consistent with the preplanned one as the values of
MasterScaling and SlaveScaling are 1 and their offsets are 0.
Case 2： The slave position corresponding to the master axis position is two times what is
planned in the cam relationship as the value of MasterScaling is 1, SlaveScaling is 2
and their offsets are 0.
Case 3： The slave position corresponding to the master axis position is 1/2 that in the planned
cam relationship as the value of MasterScaling is 1, SlaveScaling is 0.5 and their
offsets are 0.
Case 4： The master axis position corresponding to the slave axis position is 1/2 what is planned
as the value of MasterScaling is 0.5, SlaveScaling is 1 and their offsets are 0. If it is
observed from the perspective of the cam phase, the master axis cam phase is 1/2
what is preplanned. That is, the master cam cycle changes from 360 to 180
(180=360*0.5) and the slave axis cam phase is unchanged.
Case 5： The master axis position corresponding to the slave axis position is 2 times what is
planned as the value of MasterScaling is 2, SlaveScaling is 1 and their offsets are 0. If it
is observed from the perspective of the cam phase, the master axis cam phase is two
