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].
