Direct input of coordinate system shift

If the tool position assumed at programming is inputted when the coordinate system actually set is
different from the workpiece coordinate system assumed at programming, shift length of the coordinate
system actually set and the workpiece coordinate system assumed at programming is set in the workpiece
coordinate system shift value.
The procedure leading up to inputting coordinate system position depend on the setting made for bit 2
(PRC) of parameter No.5005.
The procedure in which the coordinate system position of workpiece end face is specified is as follows.

When bit 2 (PRC) of parameter No.5005 is set to 0

Cut the workpiece end face tentatively.

Display the workpiece coordinate system shift screen with touching tool to the workpiece end face.

Move the cursor to Z axis of MEASUREMENT.

Input the workpiece end face position on workpiece coordinate system assumed at programming and
press soft key [INPUT].

appropriate manual provided by the machine tool builder for the actual operations.)

Remove a tool from the workpiece end face.

Explanation

When shift values become valid

Shift values become valid immediately after they are set.

Shift values and coordinate system setting command

Setting a command (G50 or G92) for setting a coordinate system disables the set shift values.
Example)

When G50 X100.0 Z80.0; is specified, the coordinate system is set so that the current tool reference
position is X+100.0, Z+80.0 regardless of the shift values.

Shift values and coordinate system setting

If the automatic coordinate system setting is performed by manual reference position return after shift
amount setting, the coordinate system is shifted instantly.

Diameter or radius value

Whether the shift amount on the X-axis is diameter or radius value depends on that specified in program.

Position record signal

When bit 2 (PRC) of parameter No. 5005 is 1, the absolute coordinates when the position record signal
PRC is “1” are recorded for calculation of the shift amount.

When the actual position of the reference point is X=121.0 (diameter), Z=69.0 with respect to the

Setting Tool Offset / 2nd Geometry Tool Offset Values

To compensate for a difference in tool attachment position or selection position, second geometry tool
offset can be applied in addition to tool offset. As second geometry tool offset values, X-axis, Y-axis, and
Z-axis offset values can be set.
