TECH TIP – AUTOMATED REPEATABILITY SURVEY IN VERISURF
|
|
|
Repeatability Surveys are an integral part of Statistical Process Control (SPC) to ferret out systematic errors and instabilities in manufacturing processes. Verisurf makes this an easy task:
- Set up and measure your reference points to orient the laser tracker to the product in question.
- Align and then measure the points you wish to monitor. This initial measurement set is your baseline.
- Create a Plan (Report) with the baseline measurements.
- In the Report Manager, RMC on the points and select Change Measure Settings. In Measure Settings, select Automated and then OK.
- Go to Preferences, in Projection Settings set Project To, to "Point." In Auto-Inspect Settings, select Loop on completion. For details on other controls, consult our Verisurf Preference Reference Guide in the Verisurf 2021 Docs folder on your Desktop.
- In the Measure Manager, select Toggle Auto-Inspect from the toolbar.

|
- Then choose Clear All and Auto Inspect; the Plan starts.
- When using a Laser Tracker, the tracker runs in a continuous loop collecting data until stopped.
- You may "Pause" between surveys by adding a Comment to the Plan (Report).
- Select Timer Prompt and add time (in seconds) to pause between passes.
- Add a Timer Prompt between Target Points to Dwell, allowing the operator to move the SMR ahead to the next Target Point.
- You may analyze the Data within Verisurf, collect it in a database format, or export it to Excel™ for further analysis.
