C80 Series Instruction Manual
5 Setting a Tool and a Workpiece
Operation method (When the menu [MeasVal take in] is used)
(1) Execute the reference position return.
(2) Set the mode selection switch to the manual mode
(handle, jog, rapid traverse, or step).
(3) Select an arbitrary coordinate system offset.
(4) Select whether to measure the workpiece coordinate
on the main spindle side or sub-spindle side by using
tool presetter sub-side valid signal.
<Note>
Hold the state of this signal until the measure-
ment with the selected tool is completed.
(5) Issue the T command with MDI operation, etc.
(6) Cut the workpiece face slightly to even it.
<Note>
Do not move the tool in the Z axis direction after
cutting the workpiece face.
If the workpiece does not need to be cut, carry
out positioning to the measurement position.
(7) Press the menu [MeasVal take in].
IB-1501453-C
The coordinate system is established.
<Note>
If the workpiece is measured without establishing
the reference position return, the operation mes-
sage "Meas axis not returned to ref. position" ap-
pears.
The designated coordinate system offset is selected.
<Note>
When switching to an arbitrary coordinate system
offset display, press one of these menus; [Coord
G54 - G59] [Coord G54.1P] or page key.
The tool is selected.
<Note>
Set the selected tool compensation No. in R regis-
ter. The set R register differs according to parame-
ter setting and the state of the tool presetter sub-
side valid signal.
Set the "tool length/wear data" for the tool being
used beforehand.
The workpiece measurement is executed.
The operation message "OK? (Y/N)" appears, so press
the [Y] or [INPUT].
The Z axis external workpiece coordinate offset data is
automatically calculated from the tool compensation
data of the used tool and the machine value at the point
this signal is input. The results are set as the data.
