Turning Parts Recognition Conditions
- The Machined Plate service automatically recognizes round and square parts.
- This section describes the recognition conditions.
To Recognize Turning Parts
If the outer-most diameter has a cylindrical part, the shape is recognized for Turning Parts.

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” |
|---|---|
|
|
|
|
Caution
- Automatic recognition is not supported for internal threads (inner diameter) and external threads (outer diameter)
- If a “hole” is recognized, the color attribute/hole attribute linkage 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.
Caution
- If the internal corners are curved, the shape is not recognized as an “internal keyway” and the fit tolerance cannot be specified.
- If tolerance settings are required, design the keyway with sharp internal corners.
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.

End Face Groove Recognition Conditions
If the bottom of the end face groove is curved it is not recognized. Design with sharp internal corners.
Recognized as an "end face groove" |
