Programming a straight line

The tool moves at the programmed feedrate or with rapid traverse from its actual position to
the programmed end position.
Radius compensation
Alternatively, you can implement the straight line with radius compensation. The radius
compensation acts modally, therefore you must deactivate the radius compensation again
when you want to traverse without radius compensation. Where several straight line blocks
with radius compensation are programmed sequentially, you may only select radius
compensation in the first program block.
When executing the first path motion with radius compensation, the tool traverses without
compensation at the starting point and with compensation at the end point. This means that if
a vertical path is programmed, the tool traverses an oblique path. The compensation is not
applied over the entire traversing path until the second programmed path motion with radius
compensation is executed. The reverse effect occurs when radius compensation is
deactivated.
