The SMC_SmoothPath function block can be used for
trajectory preprocessing. It rounds the path angles, resulting
in a slur path.
It is used when the accuracy of the trajectory is not high, but
the speed is high, and the speed is not allowed to drop to 0.
The SMC_ToolCorr is used for path preprocessing.
The SMC_XInterpolator function block implements a mix of
CAM and CNC. Suppose you want to cut a workpiece to a
specific shape (described by G-code), according to the
movement of the workpiece by another process (for
example, moving along the X axis) and other axes (y, z, etc.)
should follow the workpiece (X) The current position is
controlled, and the target is given by the path point.
The interpolator is processing an M-function, and this
module is used to poll the parameters (K, L, O, see HERE)
that have been set for the M-function.
It is used to validate an M function before the interpolator
reaches the block. In this way, the pause on the M function
can be avoided.
The orientation of the tool (dAlpha) can be calculated when
using it.
For the gantry system, no transformation can be
performed, so the module can only add offsets to the x and
y axes.
The function block is used to reverse the tool axial offset of
the gantry system, that is, the axial offset relative to the Z
axis, and they are approximately on a straight line.
The function block is used to reverse the tool axial offset of
the gantry system, that is, the axial offset relative to the Z
axis, which is approximately a right angle.
For the gantry system, no transformation can be
performed, so the module can only add offsets to the x, y,
and z axes.
Computes an inverse transformation for a 3D gantry
system being controlled and indicating an axis of rotation
along the tangent of the path.
