Tool Lengths In The Wcs, Allowing For The Orientation - Siemens SINUMERIK 840D sl Function Manual

Example:
N10 $SC_WEAR_SIGN = 0
N20 $TC_DP1[1,1] = 120
N30 $TC_DP6[1,1] = 100
N40 $TC_DP15[1,1] = 1
N100 T1 D1 G41 X150 Y20
....
N150 G40 X300N10
....
N200 $SC_WEAR_SIGN = 1
N300 D1 G41 X350 Y-20
N310 ....
The same applies in the event that the resulting tool length is modified due to a change in the
mirroring status of an axis. The tool must be selected again after the mirror command, in order
to activate the modified tool-length components.

Tool lengths in the WCS, allowing for the orientation

Change tool or working plane
The values displayed for the tool correspond to the expansion in the WCS. If a toolholder with
an inclined clamping position is to be used, you should make sure that the transformation used
supports the toolholder. If this is not the case, incorrect tool dimensions will be displayed. When
changing the working plane from G17 to G18 or G19, you should ensure that the transformation
can also be used for these working planes. If the transformation is only available for G17
machining, the dimensions continue to be displayed for a tool in the Z direction after the plane
change.
When transformation is deactivated, the basic tool is displayed in the x, y or z direction,
according to the working plane. Allowance is made for a programmed toolholder. These tool
dimensions are not altered when traversing without a transformation.

2.14 Special handling of tool offsets
; No sign inversion of the wear values
; End mill
; Tool radius 100 mm
; Wear dimension of tool radius 1 mm, resulting
tool radius 101 mm
; Sign inversion for all wear values; the new ra-
dius of 99 mm is activated on a new selection
(D1). Without D1, the radius would continue to
be 101 mm.
