Example 20.5
Using G10 to Change The Tool Offset Table
N00001 G90;
N00002 G10 L10 P4 Z2.1 Q1; Offset number4 has a newvalue of 2.1for tooloffset inthe Z
direction and new orientationvalue of 1in geometrytable. The
current value for any axis not specifiedand for the toolradius
remain unchanged.
N00003 G10 P4 L11 Z1.1; Offset number 4has a new value of 1.1for tool offset in the Z
direction in the wear table.
N00004 G91;
N00005 G10 L10 P4Z-1 Q1; Offset number4 has a newvalue of 0.1(1.1 -- 1.) for tool offset
in the Z direction andnew orientation valueof 2 (1 + 1). The
current value for any axis not specifiedand for the toolradius
remain unchanged.
Important: G10 blocks cannot be programmed when TTRC is active.
Use the random tool feature to speed up production by saving cycle time
when a tool is returned to the tool changing device. This is done by
allowing the tool changer to randomly return the cutting tool to the most
convenient pocket in the tool changing device. The control remembers
what pocket the tool is returned to, and it is able to call the same tool from
the new pocket at any time.
Important: This feature can be used with normal tool selection or the tool
life management feature.
This feature has no effect on tool length offsets or cutter compensation.
These features must still be activated correctly as described in their
individual sections.
The random tool feature automatically decides the pocket that contains the
requested tool based on the information in the pocket assignment table. If
the requested tool has not been assigned to a pocket, the control generates
an error.
Based on the current pocket number, which is maintained by PAL, the
control tells PAL which pocket to move to, and how far, and in which
direction to move. The control also tells PAL where the tool currently in
use can fit in the tool turret.
Important: This feature is very PAL dependant. Before using this feature
make sure your system installer has written the PAL program to allow the
use of Random Tool.
The control automatically updates the tool pocket assignment table when
you make tool changes. The control indicates to PAL the best location to
return the tool to. PAL then decides where the tool gets placed in the tool
holder. The pocket that is vacated by the new tool is marked as empty.
