4.3 Tool Compensation Values
Traverse with radius compensation RL, RR
* Between two pragrm blocks tith differing radius
compensation you must program at least one btacfc without
raditls compensarian (that is, with RO).
* Radius comp&xzation is nd in affect until the end of the block in which it is first programmed.
l
Whenever radius compensation is activated of cancstted, the TAfC positions
tha tool perpendicular to the
programmed starting ar and pbsitlon. Positian the tool at a sufficient distance from the first (or Iast) Contour
point ta prevent t&a possibility of damaging the conrout-.
The tool center moves to the left (RL) or to the right (RR) of the pro-
grammed contour at a distance equal to the tool radius. "Right" or "left" is
meant as seen in the direction of tool movement as if the workpiece were
stationary.
Fig. 4.9: The tool moves at left (RL) or at right (RR) of the workpiece during milling
