2.5.2 Variable tool change point
If the manufacturer so wishes, he can let the user define the tool change point every
time. Obviously, this feature depends on the type of machine and type of tool changer.
This feature may be used to change the tool next to the part, thus avoiding movements
to a tool change point located far away from it.
To do this:
Define the text 47 of program 999997 so the CNC requests the X and Z
coordinates of the tool change point. For example: 47 $CHANGE POSITION.
T 02 D 12
S 150
CHANGE POSITION
X 25.000 Z 85.000
T 02 D 12
S 150
CHANGE POSITION
X 25.000 Z 85.000
These coordinates must be referred to machine zero point, so the zero offsets do
not affect the tool change point.
Remember that the CNC can show, next to the X, Z coordinates and in small
characters, the coordinates of the axes referred to machine reference zero (text
33 of program 999997).
Since the operator can change the tool change point at any time, the subroutine
associated with the tools must consider those values.
Arithmetic parameters P290, P291 and P292 contain the values set by the operator
as tool change position.

Press the [T] key to select the «T» field. Then press the [X] or [Z] key of the desired
axis or the [] [] [] [] keys.
After placing the cursor on the coordinates of the axis to be defined, you can:
A. Entering the value manually. Key in the desired value and press [ENTER].
B. Assign the current machine position.
Jog the axis with the handwheel or the JOG keys up to the desired point.
Press the [RECALL] key. The CNC assigns that coordinate to the selected field.
Press the [ENTER] key.
