Detailed Description
2.8 Special handling of tool compensations
Tool Compensation (W1)
2-118 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
In the case of tool types without a relevant cutting edge position, the wear length is not
mirrored.
Note
Activating the
Mirror tool lengths (SD42900 <> 0)
and
Mirror wear lengths (SD42920 <> 0)
functions can disable mirroring (sign inversion) in one or a number of components.
SD42930 $SC_WEAR_SIGN
Setting data not equal to zero:
Inverts the sign of all wear dimensions. This affects both the tool length and other variables
such as tool radius, rounding radius, etc.
Entering a positive wear dimension makes the tool "shorter" and "thinner".
Activation of modified setting data
When the setting data described above are modified, the tool components are not
reevaluated until the next time a tool edge is selected. If a tool is already active and the data
of this tool are to be reevaluated, the tool must be selected again.
Example:
N10 $SC_WEAR_SIGN = 0 ; No sign inversion of the wear values
N20 $TC_DP1[1,1] = 120 ; End mill
N30 $TC_DP6[1,1] = 100 ; Tool radius 100 mm
N40 $TC_DP15[1,1] = 1 ; Wear dimension of tool radius 1 mm, resulting
tool radius 101 mm
N100 T1 D1 G41 X150 Y20
....
N150 G40 X300N10
....
N200 $SC_WEAR_SIGN = 1 ; Sign inversion for all wear values; the new
radius of 99 mm is activated on a new
selection (D1). Without D1, the radius would
continue to be 101 mm.
