C80 Series Instruction Manual
5 Setting a Tool and a Workpiece
<Simple measurement (without the touch probe)>
(5) Move the tool in the X-direction to the arbitrary posi-
tion and press the menu [SkipPos take in].
(6) Select the workpiece coordinate system offset in
which the measurement data will be set.
(Example) To select G55
Press the menus [Coord G54-G59] [G55].
(7) Press the menu [Coord write].
(8) Carry out the operations in steps (4) to (7) in the
same way for the Y and Z axes.
(9) Return the tool to the reference position, and turn the
measurement switch OFF.

5.7.1.2 Carrying Out Hole Measurement

For hole measurement, measure the measurement position coordinate of two axes (X and Y) at three points, calculate the
center of the hole, and set the result to the designated workpiece coordinate offset. The measurement position coordinate
is displayed on the measurement counter.
<Measurement using touch probe>
Measurement counter X = X axis skip position
Measurement counter Y = Y axis skip position
<Simple measurement (measurement without using touch probe)>
Measurement counter X = X axis machine position + center compensation (H) + skip past amount (Horizontal axis) (*1)
Measurement counter Y = Y axis machine position + center compensation (V) + skip past amount (Vertical axis) (*1)
(*1) The skip past amount is added for only the axis that moved last.
The sign ( + or - ) of the past amount depends on the movement direction of the axis.
Center compensation (H)
Center compensation (V)
Skip past amount (H)
Skip past amount (V)
Item
"#8703 OFFSET X"
"#8704 OFFSET Y"
"#8707 Skip past amout(H)"
"#8708 Skip past amout(V)"
The skip position is calculated and the result displays in
the measurement counter X axis section.
The value achieved by adding or subtracting the external
workpiece offset to or from the X axis measurement po-
sition based on the "#8709 Ext work sign rvs" is set in
workpiece coordinate system selected at (6).
The measurement counter displays blank.
