You can use dynamic inspection to reduce measurement cycle time based on statistical analysis.
Measurement Process
To perform dynamic inspection, PC-DMIS follows this process:
PC-DMIS executes a measurement routine to measures a part.
PC-DMIS sends the results to Q-DAS.
Q-DAS performs statistical analysis on the data and determines the characteristics required to be measured for the next part.
Q-DAS updates the <RoutineName>.miniroutine.xml file, where <RoutineName> is the name of the measurement routine file name. This updates the mini-routine node selected for dynamic inspection, which includes the information of all the selected characteristics.
Q-DAS informs you that you can now run the entire measurement routine or just the mini-routine for dynamic inspection. Based on the information received, for the next part, you must either run entire measurement routine or mini-routine.
To set up dynamic inspection, follow these steps:
Create a measurement routine that is capable of Feature Based Measurement (FBM). To do this in PC-DMIS, you can use either the ClearanceCube or FBM option. Select the best option based on your part's complexity.
To execute the measurement routine by selecting characteristics, you need to use mini-routines. Create a mini-routine with a unique name to use for dynamic inspection and then use the mini-routine to execute the measurement routine.
Open Q-DAS Configurator (Operation | Q-DAS | Open Configurator).
Create a K-field configuration file. You can use this configuration file to measure parts that require dynamic inspection.
Select these K-fields for dynamic inspection:
K1802 - Use this field to provide PC-DMIS measurement routine directory.
K5001 - Use this field to provide mini-routine's name for dynamic inspection (You need to use the same name that you provided in Step 2).
K5002 - Use this field for mini-routine characteristic information.
From the Value From list, select the property for each K-field:
For K1802, select either QDAS_CFG or Trace.
If you select QDAS_CFG, PC-DMIS populates this field in a .dfq file with the executed measurement routine's full path name.
If you select Trace, PC-DMIS populates this field in a .dfq file with the value of a tracefield in a measurement routine. If you have automation that creates and executes a copy of your measurement routine, you can use this option. In such scenarios, Q-DAS updates the .miniroutine.xml file in your measurement routine's folder. The default folder location is:
C:\Users\Public\Documents\Hexagon\PC-DMIS\2023.1
For K5001, select Trace. You must type the mini-routine's name that you created in Step 2. Q-DAS updates the contents of this mini-routine with the selected characteristics from the measurement routine to measure the next part.
For K5002, select QDAS_CFG. PC-DMIS sends the required string for each characteristic to a .dfq file. Q-DAS updates the contents of this mini-routine with this string for each characteristic that it determines needs to be measured.
To select groups instead of individual characteristic, select RUNTIME_XML file in the Value From column.
Click Save.
You can use this configuration file in the Stats command of a measurement routine that requires dynamic inspection.
