Machine simulation: Collision Control

This page enables you to define the following settings:

Enable collision control

This option enables you to detect and avoid possible collisions between all components of the CNC-Machine in the process of machining. When the Enable collision control check box is selected, SolidCAM performs the collision checking according to the collision control parameters in the CNC-Machine definition. When the Enable collision control check box is not selected, SolidCAM ignores the collision control parameters in the CNC-Machine definition and does not perform the collision control.

Collision check tolerance

This parameter enables you to specify the tolerance of the collision check. SolidCAM ignores all the collisions with tolerance smaller than the specified value and alerts when the collision tolerance is greater than the tolerance specified value.

This value should correspond to that of the Facet tolerance parameter defined in the Stock and Target Model dialog box to avoid cases when collisions are detected because of inconsistency between these tolerance values.

Part offset

This parameter enables you to add a virtual offset surrounding the whole part at the specified distance. Collisions occurring within this boundary will be ignored.

Collision detection mode

Generally, SolidCAM performs the collision control in the generated tool path positions listed in the GCode output.

  • Discrete

This option enables you to perform the collision control on the exact tool path points between the collision checking groups as defined in the XML file.

  • Continuous

This option enables you to perform the collision control on intermediate positions between two tool path points. In this method, the collision check is limited between tool and workpiece and/or stock and fixture.

  • Interpolation

This option enables you to perform the collision control on intermediate positions between two tool path points using the Maximum distance and Maximum angle change values. This method enables you to handle the collision checking groups (e.g., tool, spindle vs. workpiece, table, fixture, stock) as defined in the XML file.

Interpolate using shortest distance

This option is enabled when the Interpolation check box is selected. With this option the tool detects the shortest path for machining in rapid motion.

  

Collision check in length-based mode

This section enables you to perform the collision check when the Length-based Mode is chosen.

  • Maximum distance

This parameter enables you to specify the step between two consecutive checking positions.

  • Maximum angle change

This parameter enables you to specify the maximal angle change allowed for the tool per each move.

When stock is split by CutOff operation

Enable Use Fixture Clamping - In a Cutoff operation after the stock is split, the split stock remains on the main spindle and the remaining stock with part moves with the Back spindle to the desired location.  

Disable Use Fixture Clamping - In a Cutoff operation after the stock is split, the entire split stock with part moves with the Back spindle to the desired location.
