40i TS - v1205 - Installation/Operation - (5/29)
2 DRO operation
2.1
Display modes.
Toggle the reading of the second axis between Z (Z1 + Z2), Z1 or Z2, when the DRO has been set for
3-axis lathe.
2.1.1
mm / inch
Toggle units between mm and inches.
This toggle is possible if the installer parameters have been set as toggle .
2.1.2
rad/diam
Toggle between radius mode and diameter mode. It only affects the X axis.
In diameter mode, the X axis display shows twice the actual distance traveled by the tool. When this
mode is active, the X axis display shows the
sign.
In radius mode, the X axis display shows the actual distance traveled.
2.1.3
inc / abs
ñ
Toggle between incremental and absolute feedback reading (counting). The status bar shows the
currently active mode.
2.1.3.1
Absolute mode:
In this mode, the coordinates (position values) are
referred to part zero.
Example on the right:
Set the DRO in absolute mode.
Set part zero (datum).
Run several passes moving the Z axis from “ 0“ to “ 63.6”
until obtaining the desired diameter.
Run several passes moving the Z axis from “ 0“ to “ 47.6”
until obtaining the desired diameter.
Run several passes moving the Z axis from “ 0“ to “ 22.6”
until obtaining the desired diameter.
2.1.3.2
Incremental mode:
The coordinate is referred to the previous point where the
axis display has been set to zero.
Set the dro in incremental mode.
Set a floating zero (Z=0) at point A.
Preset the value “22.6” for the Z axis. Run several passes
moving the Z axis from “0“ to “63.6” until obtaining the
desired diameter.
Clear Z axis.
Preset the value “25” for the Z axis. Run several passes
moving the Z axis from “0“ to “63.6” until obtaining the
desired diameter.
Clear Z axis.
Preset the value “15” for the Z axis. Run several passes moving the Z axis from “0“ to “63.6” until
obtaining the desired diameter.
