Mill/Turn merging Post strategyHi Leigh,
For Constant load, make sure to set RAMP_ANGLE to a value other than the
default 90 deg. Also, helical_dia controls how wide a helical entry move to
use (I think it uses a default of twice step_over if you don't set it).
Also, a confusion might be that the approach is not really a helical entry.
Notice that the move is a spline that is tangent to both the plunge move and
the cut move to get a continuous toolpath there. It may be that you have
tight step_over or step_depth so you are not seeing much unless you change
it from 90 degrees.
For this type of spline approach, since it is not a constant helix,
ramp_angle means that the spline starts over at 90 degrees when it comes
from the plunge move, and gradually gets shallower until it reach the angle
specified in ramp_angle when it hits the material (usually step_depth value
above the slice).
I hope this helps,
