Tool Selection - Flute Length

When you specify tool selection criteria based on Use Expression and not on a specific tool, SOLIDWORKS CAM accounts for the tool's flute length.

When you run Generate Operation Plan, for each operation that you define the tool selection criteria with a Tool diameter lower/upper expression, the following rules apply:
  • If the tool crib has two or more tools with identical diameter values matching the expression criteria, SOLIDWORKS CAM accounts for the flute length to assign the tool. It selects the tool with a flute length more than the feature depth. If all tools have a flute length more than the feature depth, SOLIDWORKS CAM selects the tool with a flute length closest to the feature depth.
  • If SOLIDWORKS CAM still finds two or more tools, it uses the rules of Stock/Tool Material Mapping to select a tool.

For example, consider a rectangular pocket with a feature depth of 75mm. Based on the feature strategy assigned to this feature, the tool selection criteria selects a 25mm Flat End Mill. The tool crib has two Flat End Mill tools with identical diameters of 25mm. However, one tool has a 50mm flute length and the other has an 80mm flute length. SOLIDWORKS CAM selects the tool with the 80mm flute length because it is closer in value to the feature depth.
