Tool model (#140 / #5-03-2)
Application
With the tool model, you can add to a tool definition (e.g., for forward or reverse deburring tools).
The tool model will be used in the following functions only:
- Representation in the Simulation workspace
- Consideration in Dynamic Collision Monitoring (DCM (#40 / #5-03-1))
The control will not use the tool model for path contours (e.g., for radius compensation or the FUNCTION TCPM function).

Requirements
- Collision Monitoring v2 (#140 / #5-03-2) software option
- The tool has been defined in tool management
- A suitable tool model exits
You must save the tool model in the Toolshapes folder.
Path: TNC:\system\Toolshapes
- The tool model has been assigned to the tool
Description of function
You can use the tool model for the following tool types:
- Milling tools
- Drilling tools
- Touch probes
Tool model requirements
General requirements
The tool model must meet the following general requirements:
- Use permitted characters for the file name
- Use a supported format
- M3D file
- STL file
- Max. 20 000 triangles
- Triangular mesh forms a closed shell
- Tip
For tool models, the same requirements with respect to STL and M3D files apply as for fixtures.
Coordinate system requirements
The coordinate system of the tool model must meet the following requirements:
- The Z axis is the rotary axis of the tool model.
The control will align the tool model parallel to the tool coordinate system T-CS.
- The coordinate origin of the 3D model must be identical to the measured point of the tool. If you measure the tool at the tool tip, you also need to set the coordinate origin of the 3D model to the tool tip.
- Tip
If you measured a spherical cutter at the center of the sphere, you need to set the coordinate origin to the center of the sphere as well.
Assigning a tool model

The tool model will be taken into account only after the next tool call.
Notes
- The control will always take an assigned tool model into account (e.g., for the tool radius R=0). The simulation shows the correct shape of the tool model (e.g., in conjunction with a CAM output (center path)).
- When you delete a tool, make sure to remove the tool model from the Toolshapes folder as well. This way, you can avoid that the tool model is accidentally referenced for another tool.
- The LCUTS column of the tool table is independent of the datum of the tool model. The value is measured from the tool tip of the tool and is effective in the positive Z axis direction.
- Even if the inch unit of measure is active in the control or NC program, the control will interpret dimensions of 3D files in mm.
