Configuring Fanuc Tool Offsets

Tool offsets can be gathered from supported Fanuc controllers for as many tools as you have loaded. You may indicate to the connector how many offsets you are using on the controller using the adapter configuration text field.

To enable collection of tool offset rows, edit the machine and select "Data Collection".

Edit the data collection method:

Enter the following into the configuration where the value of maxTools indicates how many offset rows are in use on your controller. The following assumes a table containing 2 offsets.

{
  "offsets": {
    "maxTools": 2
  }
}

When completed save the adapter configuration.

Data Mapping

The first 32 rows of tool offset information are pre-mapped. Fanuc controllers can support as few as 32 or as many as 2000 tool offset rows. If your use case mandates mapping more than 32 tool offsets.

The available keys are listed below, each key suffixed by T# where # is the represented tool offset row. Different controllers have access to a different subset of the full list of keys below.

Note: 0i/30i - 0i's with 30i capabilities enabled are supported for items listed as 30i in this article.

Tool Offset Key Description:

• TipT#        | Tip direction (may not be enabled)
• LgeoT#     | Tool length geometry
• LwearT#    | Tool wear geometry
• RgeoT#     | Tool radius geometry
• RwearT#   | Tool radius wear
• XgeoT#    | X-Axis Geometry
• XwearT#  | X-Axis Wear
• YgeoT#    | Y-Axis Geometry
• YwearT#  | Y-Axis Wear
• ZgeoT#   | Z-Axis Geometry
• ZwearT# | Z-Axis Wear

Tool Offset Key Availability:

Lathe 4th/5th Axis Tool Offsets

Lathe series 30i support offsets for the 4th and 5th axis under the following keys:

• 4thGeoT#
• 4thWearT#
• 5thGeoT#
• 5thWearT#

Machining CornerR Offsets

Machining 30i can support CornerR and report under the following keys:

• cnrRgeoT#
• cnrRwearT#

Lathe Series 2nd Geometry

Lathe series machines (not 30i) support 2nd Coordinate geometry offsets under the following keys: 

• Xgeo2T#
• Ygeo2T#
• Zgeo2T#

Data Mapping

Now go into data mapping and select the new data item suffixed by the tool #. Below we see an image for row containing the data for T1. Map that data item to the proper type. In this example, we'll see Info as the Type, and Custom subtype.

Now the data item will be mapped and you can use this information to trigger workflows, classify downtime, or for a dashboard display.
