Milling tool dimensions
Diameter
Diameter of the cutting portion of the tool.
Length
Exposed length of the drill tool from tip to end. Any portion of the tool seated in a drill chuck or tool holder should not be included in the length.
Length is used for TCP placement and collision detection.
Flute length
Length of the fluted cutting section of the drill bit. The fluted section is indicated in yellow in the Preview and the viewport.
Shoulder length
Length of the fluted section plusthe smooth section of the drill tool. The smooth section of the tool has the same diameter as the fluted section.
If the entire explosed tool is fluted, set:
Shoulder length = Flute length = Length
Arbor diameter = Diameter
Arbor diameter
If the tool has an arbor at the shank end, you can enter a diameter for it. Including an arbor in the model allows you to see depth limits for the tool relative to a hole and can help with collision detection.
Arbor length is automatically calculated based on Length, Flute length, and Shoulder length.
If the entire tool is the same diameter, set:
Arbor diameter = Diameter
Tip angle
Certain drill bits have an angled tip, such as a counter sink.
...
Note that entering a tip angle has no effect on the length of the tool.
When defining tool geometry, keep in mind that cell collision detection can be refined such that the flute, arbor, and holder are treated separately for collisions. If the flute is excluded from the collision group, it will allow the flute to come into contact with the workpiece without causing a collision in Robotmaster.
