FANUC Series 30i-MODEL A
Input of tool offset value measured
General
The function is automaically setting offset value by the differennce between absolute
coordinate value and the length of workpiece
Details
This is a function of setting an offset value by key-inputting a workpiece diameter manually
cut and measured from the MDI keyboard.First the workpiece is cut in the longitudinal or
cross direction manually.When the position record signal is turned “1” (prepare a button on
the machine operator’s panel) on completion of the cutting, the workpiece coordinate value of
X axis(X axis of the basic three axes) and Z axis(Z axis of the basic three axes) at that time is
recorded in the CNC. Then, withdraw the tool, stop the spindle, and measure the diameter if
the cutting was on the longitudinal direction or measure the distance from the standard face if
the cutting was on the facing. (The reference face is made as Z = 0.) When the measured
value is entered on the offset value display screen, NC inputs the difference between the input
measured value and the coordinate value recorded in NC, as the offset value of the offset
number. If you release the tool without moving the tool in the axis along which an offset
value is entered but moves the tool along the other axis, an offset value can be set without
using the position record signal. The workpiece coordinate system can be shifted using the
technique of directly inputting the measured value for offset. This technique is used when the
coordinate system planned in the program does not match with the coordinate system actually
set. The procedures are the same as those for direct input for offset, except a difference of
using the standard tool on the work shift screen.
Signal
Position record signal PRC
<G040#6>
[Classification] Input signal
[Function] This signal is prepared for the function of input of offset value measured
A. It is used to store in the control unit the data on the positions of the
tool for tentative cutting. After measuring a dimension of the workpiece,
input the measured value by the specified manual operation. The
difference is then stored as the specified tool compensation value.
[Operation] The control unit stores the current position along X and Z axes when the
signal turns to “1”.
NOTE
To use this signal, set parameter PRC (No.5005#2) to 1.
