(6) ARC
Pressing the [
]or [ ] soft key selects an arc.
DIRECTION B: Direction of the are rotation
RADIUS R: Specify the radius of an arc. A positive
number with a decimal point is to be
specified.
ARC END X X: Absolute X–axis coordinate of the end
point
END Z Z: Absolute Z–axis coordinate of the end
point
ANGLE J: Center angle of an arc
CENTER X COORD I: Absolute X–axis coordinate of the arc
center
CENTER Z COORD K: Absolute Z–axis coordinate of the arc
center
ROUGHNESS SR: The roughness of the finished face is
selected by the soft key. The
roughness specified by the process
data is set automatically.
NOTE
An arc of a half circle or longer cannot be input. For bar
machining or pattern repeating, an arc extending over three
quadrants cannot be input even if the arc is shorter than an
arc of a half circle.
(7) CHAMFER
Pressing the [CHAMFR] soft key selects chamfering.
BEVEL AMOUNT I:
I
I: Chamfer amount
ROUGHNESS SR: The roughness of the finished face is
selected by the soft key. The
roughness specified by the process
data is set automatically.
