Detailed Description
2.5 Toolholder with orientation capability
Tool Compensation (W1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-101
A new toolholder is activated immediately when it is programmed. It is not necessary to
change tools or reprogram the active tool. The toolholder (number) and tool (number) are
independent and can be used in any combination.
Toolholder from G code of group 42
Absolute tool orientation TCOABS (Tool Carrier Orientation ABSolute):
Tool orientation is determined explicitly if the corresponding values are entered in system
variable $TC_CARR13 or $TC_CARR14 and G code TCOABS is activated in G-code
group 42.
Frame tool orientation TCOFR (Tool Carrier Orientation FRame):
Tool orientation can also be determined automatically from the current orientation of an
active frame when selecting a tool, if one of the following G codes is active in G-code
group 42 when the toolholder is selected:
• TCOFR or TCOFRZ
The toolholder with orientation capability is set so that the tool points in the Z direction.
• TCOFRX
The toolholder with orientation capability is set so that the tool points in the X direction.
• TCOFRY
The toolholder with orientation capability is set so that the tool points in the Y direction.
The effect of TCOFR is such that, when machining on an inclined surface, tool
compensations are considered implicitly as if the tool were standing vertically on the surface.
Note
The tool orientation is not bound strictly to the frame orientation. When a frame is active and
G code TCOABS is active, you can select a tool, whereby the orientation of the tool is
independent of the orientation of the active frame.
Following tool selection, you can change the frame, which does not affect the components of
tool length compensation. It is then no longer certain that the tool is positioned perpendicular
to the machining plane. You should therefore first check that the intended tool orientation is
maintained on an inclined surface.
When TCOFR, etc., is active, the tool orientation used in the tool length calculation is always
determined from the active frame each time the toolholder is changed.
