9 ARC
Function This moves the spindle head in an arc.
Value ❶ Relative location from the start point to the center of the circle (X and Y coordinates)
Value ❷ Angle from the arc start point to end point (-360 to 360 deg.)
Value ❸ Resolution (0 to 120 deg.)
Value ❹ Feed rate (0 to 50 mm/s)
This moves from the present location in an arc of the specified angle. Arc movement is possible only on the X and Y
plane.
◆ Detail Screen 1
Specify the center of the circle. Specify relative coordinates from the present location, which is the start point. Note that
these are not coordinates referenced to the workpiece origin point. To go to Detail Screen 2, press the [ENTER/PAUSE]
button. To cancel and return, press the [MENU] button.
◆ Detail Screen 2
Specify the angle from the start point to the end point. The direction of turning is determined by whether the value is
positive or negative. A positive value yields counterclockwise turning and a negative value yields clockwise turning. To
go to Detail Screen 3, press the [ENTER/PAUSE] button. To cancel and return, press the [MENU] button.
◆ Detail Screen 3
Specify the resolution (smoothness) of the arc. Smaller values result in greater smoothness, but the apparent feed rate
becomes slower. Specifying [0] sets the machine's highest resolution. To go to Detail Screen 4, press the [ENTER/
PAUSE] button. To cancel and return, press the [MENU] button.
◆ Detail Screen 4
Specify the feed rate. Specifying [0] sets a speed of 0.5 mm/s. To finish setting the value, press the [ENTER/PAUSE]
button. To cancel and return, press the [MENU] button.
