Path-dependent angle compensation at block search (#VECTOR OFFSET)

#VECTOR OFFSET

If path-dependent angle compensation (#VECTOR OFFSET) is active at the restart position of the NC program, the compensation is produced separately at automatic restart (see also #CAX TRACK).

The following sequence runs at restart:

• (Align the C axis according to the tangent at the restart position)
• Align the angle vertically and tangentially to the contour (ANC, DRC)
• Restart according to the block search position
• Reactivate (automatic C axis tracking and) path-dependent angle compensation
• Wait for continue from operator/HMI/PLC

Programing Example

Block search at N40 at ANC/DRC angle offset

In the example below, the vector offset at restart to block N40 is first set according to the active setting of block N30.

%block-search-vector-offset

N10 #VECTOR OFFSET ON [ DS=20 DE=15 ANC=2 DRC=3
                                    ANCE=0.5  DRCE=0.2 ]

N20 G01 G90 X100 Y0 F200

N30 #VECTOR OFFSET ON [ DS=1 DE=1 ANC=0.5 DRC=0.2]

N40 G03 X110 Y10 J10 F75

N50 #VECTOR OFFSET ON [ DS=15 DE=20 ANC=2 DRC=3
                                    ANCE=0.1  DRCE=0.1 ]

N60 G01 Y115

N70 G01 Y0

…

N100 #VECTOR OFFSET OFF ALL

M30

Notice

The vector offset is only restarted if automatic restart to the contour is selected (see also mc_cmd_bs_auto_return_w).
