z Machining a inner sidestep less than 90°
When the system machines a inner sidestep less than or equal to 90°and the machining
path length is less than the tool nose radius, there will be the too much undercut and No. 260
alarm occurs. At the moment, No.5008 Bit6 (CNS) sets whether the system alarms in the
condition.

z Corner motion
When two or more than movement vector in the end point of one block create, the tool moves to
another vector from the vector linear, which is called the corner motion. When the single block is
valid, the tool stops in the last vector.
When two vectors coincide, the system does not execute the corner motion and the second
vector will be ignored. When the two-axis increments of the movement vector in the
compensation level are less than the setting values of No. 5010(CLV), the second vector is
ignored, but it is not ignored when the interpolation block is the arc.
