Consideration of a limitation surface (CUT3DCC, CUT3DCCD)
Function
3D circumferential milling with real tools
In 3D circumferential milling with a continuous or constant change in tool orientation, the tool
center point path is frequently programmed for a defined standard tool. Because in practice
suitable standard tools are often not available, a tool that does not deviate too much from a
standard tool can be used.
CUT3DCCD takes account of a limitation surface for a real differential tool that the
programmed standard tool would define. The NC program defines the center-point path of a
standard tool.
CUT3DCC with the use of cylindrical tools takes account of a limitation surface that the
programmed standard tool would have reached. The NC program defines the contour on the
machining surface.

Note
Tool radius compensation with G41, G42
If tool radius compensation with G41, G42 is programmed when CUT3DCCD or CUT3DCC is
active, the option "orientation transformation" must also be active.
Standard tools with corner rounding
Corner rounding with a standard tool is defined by the tool parameter $TC_DP7. Tool
parameter $TC_DP16 describes the deviation of the corner rounding of the real tool
compared with the standard tool.
