Some of our more popular machine drivers support automatic true position bonus relationships set up during data collection. These CMMs send enough information for QC-CALC Real-Time to create these relationships automatically.
For CMMs that cannot do this, we offer a way to get that information to QC-CALC Real-Time through the Characteristic Labels. QC-CALC Real-Time looks for a specific, standard format in the label, and if that format is detected, the encoded information is extracted, and the true position bonus relationship is applied.
Standard Label Format
QC-CALC Real-Time will look for characteristic labels with the following format: NormalLabel_TP0001_T_B
Note: The standard label format TP####_T_T, TP####_D_H, TP####_Y, etc., must come at the very end of the label. That is where QC-CALC will look for it.
where NormalLabel is your typical characteristic label. The key part is everything after the first underscore. TP0001_T_B is the standardized portion of the label that QC-CALC Real-Time will use to auto-apply the true position relationship. The 4-digit number is the identifier. The characters that follow the identifier (preceded by underscores) define the kind of TP relationship.
The identifier:
- Must be a four-digit number (e.g., 0001)
- Must have both starting and ending underscores (e.g., _TP0001_)
- "TP" must be capitalized (e.g., TP0001)
- Must be the same number in all characteristics that will form the TP relationship
After the identifier, there are either one or two characters, each with a preceding underscore:
_T_B | This characteristic is a True Position with a base tolerance. |
_T_T | This characteristic is a True Position with a total tolerance (bonus included). |
_D_H | This characteristic is a Diameter and is a Hole or ID. |
_D_P | This characteristic is a Diameter and is a Pin or OD. |
_X | The circular TP scatter plot will use this characteristic on the x-axis. |
_Y | The circular TP scatter plot will use this characteristic on the y-axis. |
The characters above tell QC-CALC Real-Time whether the characteristic is a true position, a diameter, or whether to use the characteristic in a TP scatter plot (on the x or y axes)
For example, Feature 1_TP0001_T_T tells QC-CALC Real-Time that this characteristic is a true position and has a total tolerance (with an included bonus). QC-CALC Real-Time will use the information encoded in the label to create the appropriate true position relationship.
If you want Feature 1_TP0001_T_T to be applied to a TP relationship with an OD characteristic, then you will want to send the following label for the OD characteristic: Feature 2_TP0001_D_H
As you can see, the 4-digit identifier allows QC-CALC Real-Time to determine which incoming characteristics should form that particular true position relationship.
QC-CALC Configuration Options
There are additional configuration options in QC-CALC Real-Time for this feature:
TrimStandardLabels_WhenAutoApplyTPRelationships
When enabled, QC-CALC Real-Time will trim the label to remove everything after NormalLabel. This effectively gives you your original labels without the TP identifier and characters appended. QC-CALC Real-Time will still auto-apply the TP relationship defined by the label before trimming. To enable this setting, set the value to “1”; to disable it, set it to “0”.
