(2) Explanation of input items
R : CUT PT. U/R
– CUT PT. U (U–axis machining)
Specify the U coordinate (using the workpiece coordinate system) for a cutting start point by en-
tering a radius value. If this item is not specified, an automatically calculated point is used for
machining.
<Automatic calculation>
– CUT PT. U = [Outer width/2] + [cutting condition No. 793]
– R (Hole preparation)
This item specifies the Z coordinate of the cutting feed start point of hole machining. This item
is automatically determined once the [F.S.AUTO] soft key has been pressed.
This data item is not used for this machining.
Z : CUT PT. Z/Z
– CUT PT. Z (U–axis machining)
Enter the Z coordinate (using the workpiece coordinate system) for a cutting start point. If this
item is not specified, an automatically calculated point is used for machining.
<Automatic calculation>
– CUT PT. Z = [Workpiece surface Z coordinate] – [start point Z coordinate]
– Z (Hole preparation)
This item specifies the Z coordinate of the deepest point of the tool during cutting feed for hole
preparation. This item is automatically determined once the [F.S.AUTO] soft key has been
pressed.
This data item is not used for this machining.
E : DWELL
Specify a dwell time (in seconds) observed at the bottom of a groove. If this item is not specified,
an automatically calculated value is used for machining.
<Automatic calculation>
– Dwell time = [Time per rotation] * [cutting condition No. 800]
