2.6.2 Variable tool change point<br />
If the manufacturer so wishes, he can let the user define the tool change point every time. Obviously,<br />
this feature depends on the type of machine and type of tool changer.<br />
This feature may be used to change the tool next to the part, thus avoiding movements to a tool<br />
change point located far away from it.<br />
To do this:<br />
Define the text 47 of program 999997 so the <strong>CNC</strong> requests the X, Y, Z coordinates of the tool<br />
change point.<br />
For example: ;47 $CHANGE POSITION<br />
These coordinates must be referred to machine zero point, so the zero offsets do not affect the<br />
tool change point. Therefore, the <strong>CNC</strong> can show, next to the X, Y, Z coordinates and in small<br />
characters, the coordinates of the axes referred to machine reference zero.<br />
Text 33 of program 999997 must be defined so the <strong>CNC</strong> shows the coordinates of the axes<br />
referred to machine reference zero.<br />
For example: ;33 $MACHINE ZERO<br />
Since the operator can change the tool change point at any time, the subroutine associated with<br />
the tools must consider those values. Arithmetic parameters P290, P291 and P292 contain the<br />
values set by the operator as tool change position in X, Y and Z respectively.<br />
In subroutine 55 of the previous section, the line setting the movement to the tool change point must<br />
be modified:<br />
Where it says:<br />
G0 G53 XP??? YP??? ZP??? ; Movement to the tool change point.<br />
It must say:<br />
Arithmetic parameter P290.<br />
Change position in X.<br />
Arithmetic parameter P291.<br />
Change position in Y.<br />
Arithmetic parameter P292.<br />
Change position in Z.<br />
G0 G53 XP290 YP291 ZP292 ;User-defined movement to the change point.<br />
Define the coordinates of the tool change point (X, Y, Z)<br />
1. Press the [T] key to select the «T» field.<br />
2. Then press the [X], [Y] or [Z] key of the desired axis or the [] [] [] [] keys.<br />
3. After placing the cursor on the coordinates of the axis to be defined, define the desired values.<br />
After placing the cursor on the coordinates of the axes to be defined, the value is entered in one<br />
of the following ways.<br />
Entering the value <strong>manual</strong>ly. Key in the desired value and press [ENTER].<br />
Assign the current machine position.<br />
Jog the axis with the handwheel or the JOG keys up to the desired point. Press [RECALL] so<br />
the selected data assumes the value shown in the top right window and press [ENTER].<br />
The top right window shows the tool position at all times.<br />
