The control distinguishes the following presets on the tool for different calculations or applications.

Tool carrier reference point
![]() | ![]() |
The tool carrier reference point is a fixed point defined by the machine manufacturer. The tool carrier reference point is usually located on the spindle nose.
Starting from the tool carrier reference point, define the tool dimensions in the tool management (e.g., length L and radius R).
Tool tip TIP
![]() | ![]() |
The tool tip has the greatest distance from the tool carrier reference point. The tool tip is the origin of the tool coordinate system T-CS.
In case of milling cutters, the tool tip is at the center of the tool radius R and at the longest point of the tool on the tool axis.
- You define the tool tip with the following columns of the tool management relative to the tool carrier reference point:
- L
- DL
- ZL (option 50, option 156)
- XL (option 50, option 156)
- YL (option 50, option 156)
- DZL (option 50, option 156)
- DXL (option 50, option 156)
- DYL (option 50, option 156)
- LO (option 156)
- DLO (option 156)
In the case of lathe tools (option 50) the control uses the theoretical tool tip, i. e. the longest measured values ZL, XL and YL.
Tool center point (TCP, tool center point)
![]() | ![]() |
The tool center point is the center of the tool radius R. If a second tool radius (R2) is defined, the tool center point is offset from the tool tip by this value.
In the case of turning tools (option 50), the tool center point is at the center of cutter radius RS.
Making entries in the tool management relative to the tool carrier reference point defines the tool center point.
Tool location point (TLP, tool location point)
![]() | ![]() |
The control positions the tool on the tool location point. By default, the tool location point is at the tool tip.
In the FUNCTION TCPM function (option 9), you can also choose the tool location point to be at the tool center point.
Compensating for the tool angle of inclination with FUNCTION TCPM (option 9)
Tool rotation point (TRP, tool rotation point)
![]() | ![]() |
When applying the tilting function with MOVE (option 8), the control tilts around the tool rotation point. By default, the tool rotation point is at the tool tip.
When selecting MOVE in PLANE functions, the syntax element DIST is used to define the relative position between the workpiece and the tool. The control shifts the tool rotation point from the tool tip by this value. When DIST is not defined, the control keeps the tool tip constant.
In the FUNCTION TCPM function (option 9), you can also choose the tool rotation point to be at the tool center point.
Tool radius 2 center (CR2, center R2)
![]() |
The control uses the tool radius 2 center in conjunction with 3D tool compensation (option 9). In the case of straight lines LN, the surface normal vector points to that point and defines the direction of the 3D tool compensation.
3D tool compensation (option 9)
The tool radius 2 center is offset from the tool tip and the cutting edge by the R2 value.
