Presets on the tool

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

Tool carrier reference point

Werkzeugträgerbezugspunkt
Werkzeugträgerbezugspunkt_Dreh

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 management

Tool tip TIP 

TIP
TIP_Dreh

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.

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)

Tool data for the tool types

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)

TCP_01
TCP_Dreh

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 data for the tool types

Tool location point (TLP, tool location point)

Tool rotation point (TRP, tool rotation point)

TRP
TRP_Dreh

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.

Rotary axis positioning

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)

CR2

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.
