Gouge check

The Gouge check page enables you to define the parameters used for automatically detecting and avoiding possible collisions between the tool, the tool holder, and the workpiece.

Degouging

Check

This option enables you to specify the detection method used for collision checking:

• Guide curves only – gouges are automatically checked with guide curves only. All other Degouging parameters are deactivated when using this option.
• Swarf surfaces – gouges are checked only with swarf surfaces.
• Additional surfaces – gouges are checked only with check surfaces.
• Swarf & additional surfaces – gouges are checked with both swarf and check surfaces.

Collision handling

This option enables you to specify the handling of detected collisions:

• Degouge – completely degouges the surface for a collision free tool path. The accuracy of degouging is defined in the Gouge allowance field. You can select the appropriate surface from the Check surfaces list or define a new one by clicking .
• Balance – balances the gouge and excess material ratio by equalizing the amount of rest material and gouging. When this option is selected, the Gouge allowance and Excess material allowance parameters are not available.
• Balance within allowance – sets the maximum thresholds of gouge and excess material. The Excess material allowance parameter specifies the amount of excess material allowed on the walls of the machined surface while degouging.

Avoid by relinking

This option enables you to trim the colliding tool path segments with selected collision check surfaces which you can select from the Check list. You can select the appropriate surface from the Check surfaces list or define a new one by clicking .

The offset from the checked faces can be defined in the Check faces clearance field.

Avoid by retracting

This option enables you to retract the tool from arbitrary check surfaces. This colllision check strategy allows you to extend the tool path cutting range. You can select the swarf surfaces by selecting the Check against swarf surface check box or the appropriate surface from the Check surfaces list or define a new one by clicking .

The offset from the checked faces can be defined in the Check faces clearance field.

Direction

This section allows you to specify in which direction the tool retracts in case a collision is detected. The Direction list has the options of Along tool axis and Along contact line.

Clearance data

The Clearance data page enables you to define the clearance offsets for arbor and tool holder in order to get a guaranteed clearance gap between arbor, tool holder and workpiece.

Tool clearance values

The Shaft, Arbor and Holder parameters define the offsets applied to the corresponding parts of the tool.
