Tool Radius Compensation - Siemens SINUMERIK 828D Programming Manual

Tool radius compensation

The contour and tool path are not identical. The milling tool or cutting edge center must
travel along a path that is equidistant from the contour. To do this, the control requires data
about the tool form (radius) from the tool compensation memory.
Depending on the radius and the machining direction, the programmed tool center point path
is offset during the program processing in such a way that the tool edge travels exactly along
the programmed contour:
NOTICE
Tool radius compensation is applied according to the default CUT2D or CUT2DF
(see "2D tool compensation (CUT2D, CUT2DF) (Page 329)").
References
The various options for the tool radius compensation are described in detail in Section
"Tool radius compensations".
