With normal high-accuracy control, because the angle between two blocks is compared with the corner
deceleration angle to determine whether to execute corner deceleration between the blocks, there may be a
case where sudden speed fluctuation occurs between blocks with an angle close to the corner deceleration
angle.
With SSS (Super Smooth Surface) control, the large area path information is used instead of just the angle
between the blocks. Thus, optimum speed control that is not adversely affected by minute steps or waviness
is possible. This enables machining with fewer scratches and streaks on the cutting surface compared to the
normal high-accuracy control function.
