 From the relationship between the master axis position
Relationship between pre-planning software cam master-slave relationship between the
position of the axis, "position" herein from the main phase of the cam shaft, rather than the
actual axis position. If the relationship between the cam as a function of pre-planned CAM,
CAM input is a function of the phase of the cam shaft, the output shaft from the cam phase,
as follows:
y = CAM (x)
x: spindle cam phase
y: the phase of the cam shaft from
From the phase position of the cam shaft, there is a conversion between them.
MasterAbsolute parameter conversion relationship between the shaft position and the cam
phase, SlaveAbsolute, MasterOffset, SlaveOffset, MasterScaling, SlaveScaling, please refer
to the relevant details.
Cam follower shaft from the spindle do MC_CamIn synchronized movement under the
action of the instruction. Synchronous movement of the cam, Slave axis position of the main
shaft of the cam to establish correspondence between pre-planning relationship (cam curve or
cam table) based on the calculated position of the spindle axis from the position of the shaft
Process is shown below:
 MasterAbsolute and SlaveAbsolute
MasterAbsolute correspondence relationship between the parameters used to specify the
position of the spindle axis and its cam phase: When the parameter is TRUE, the absolute
relationship; when the parameter is FALSE, the relative relationship. SlaveAbsolute
MasterAbsolute parameters and empathy.
MasterAbsolute SlaveAbsolute parameters and acting on the engagement start timing,
that is, a correspondence relationship between the shaft position and the cam phase to
establish engagement start timing (note: the corresponding relationship is established by
engaging actions of the start time, rather than MC_CamIn instruction starts execution time).
After this, the cam phase calculation, in accordance with the correspondence relation.
