Tool radius compensation on circular arc
or helix with angular length = 0 The transition between the adjacent
elements of the arc/helix is generated.
Also, the tool axis motion is executed
right before this transition. If the
element is the first or last element to be
corrected, the next or previous element
is dealt with in the same way as the first
or last element to be corrected The equidistant line of the arc/helix is
used for generating the tool path
Checking the algebraic sign of the depth
parameter in fixed cycles Must be deactivated if Cycle 209 is used No restrictions
Tool change while tool radius
compensation is active Program cancelation with error message Tool radius compensation is canceled,
tool change is performed
Compensation of tool length in the
position display The values L and DL from the tool table
and the value DL from the TOOL CALL are
taken into account in the position display The values L and DL from the tool table
are taken into account in the position
