Detailed Description
2.7 Basic tool orientation
Tool Compensation (W1)
2-112 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Indexing: Same as tool system variable $TC_DPx[t, d]
t: T number of cutting edge
d: D number of cutting edge
Identifiers $TC_DPV3 to $TC_DPV5 are analogous to identifiers $TC_DP3 to $TC_DP5 of
the tool length components.
MD18114
The system variables for describing the tool orientation are only available if machine data:
MD18114 $MN_MM_ENABLE_TOOL_ORIENT
is set to a value other than zero.
MD18114 $MN_MM_ENABLE_TOOL_ORIENT
Value = 1 Only system variable $TC_DPV[t, d] is available.
Value = 2 All four system variables are available.
Define direction vector
If all four system variables contain 0, the orientation is defined only by the active plane (as
before).
If system variable $TC_DPV[t, d] is equal to zero, the other three parameters - if available -
define a direction vector. The amount of the vector is insignificant.
Example:
$TC_DPV[1, 1] = 0
$TC_DPV3[1, 1] = 1.0
$TC_DPV4[1, 1] = 0.0
$TC_DPV5[1, 1] = 1.0
In this example, the basic orientation points in the direction of the bisector in the L1L3 plane,
i.e., the basic orientation in the bisector for a milling tool and active plane G17 lies in the Z/X
plane.
Basic orientation of tools
Basic orientation of: With :
Turning and grinding tools
G18
Milling tools
G17
The active tool orientation is unchanged in these cases and is equivalent to the original
settings in $TC_DPVx[t, d].
