CNC Turned parts Recognition Conditions

  • CNC Milling automatically recognizes round and square parts.
  • This section describes the recognition conditions.

To Recognize CNC Turned parts

If the outer-most diameter has a cylindrical part, the shape is recognized for CNC Turned parts.

Turning Part Recognition Recognition of CNC Milled parts
  • *The outer-most diameter is cylindrical
  • *The external corner fillet and outer-most shape form a square
  • *The outer-most diameter cylindrical surface exceeds a total of 140°
  • *The outer-most diameter cylindrical surface is 140° or less

Outer Diameter and Inner Diameter Recognition Conditions

The inner diameter and outer diameter are recognised based on their positional relationship with the central axis.

Recognition of O.D. and I.D.

 Not recognition as “Outer- and Inner Diameter”
  • *Since it is on the central axis, it is recognized as an O.D.
  • *Since it is not on the central axis, it is recognized as an "unsupported shape" instead of an O.D.
  • *Since it is on the central axis, it is recognized as an I.D.
  • *Since it is not on the central axis, it is recognized as an "hole" instead of an I.D.

Caution

  • Automatic recognition is not supported for external threads (outer diameter)
  • If a “internal threads (inner diameter) and hole” is recognized, the color attribute/CAD attribute link age function is enabled.＞Automatic Hole Type Recognition

Keyway Recognition Conditions

For keyways that match the JIS standard (B 1301:1996), tolerances are automatically set and can be changed in the dialog. *The default settings can be customized in user settings.

Key width specification
Recognized as a keyway
Not recognized as a keyway
Width recognized as an external keyway (keyseat)
Matches [b1] specifications: The fit tolerance of the external keyway (keyseat) is set automatically
Does not match [b1] specifications: The fit tolerance of the slotted hole is set manually
Width recognised as an internal keyway
Matches [b2] specifications: The fit tolerance of the internal keyway is set automatically
Does not match [b2] specifications: Handled as "general tolerance" for internal keyway and the tolerance cannot be specified

Caution

  • If the blind internal corners are not rounded, the shape is not recognized as an “external keyway” and the fit tolerance cannot be specified.
  • If tolerance settings are required, design the keyseat with round corners that match the groove width.

Cylinder Side Hole Recognition Conditions

  • A Hole that is oriented to the central axis will be recognized as a “hole” for automatic quotation.
  • If it is not oriented to the central axis, it will be recognized as an “other hole” and is not supported by automatic quotation.
  • A chamfer will be added to the top of the hole during machining whether or not one is included in the model.
Cylinder Side Hole Recognition Conditions

Recognized as a "hole"

 Not recognized as a "hole"
  • *Recognised as a hole because it is oriented to the central axis
  • *Recognised as a "hole" because it is oriented to the central axis
  • *Recognizes as an "other hole" since it is not oriented to the central axis Enter the hole information in the comments field to request a manual quotation
