Sample Sets

A Sample Set is a collection of Sample Ranges that define how many measurements should be taken based on the number of Parts in a Batch, as assigned by a Spec Field Assignment Parameter, for quality control. Each sample range specifies:

• Min Batch Count: The minimum number of parts in a batch for this range
• Max Batch Count: The maximum number of parts in a batch for this range (can be unlimited)
• Sample Count: A fixed number of samples to take (e.g., "5 samples")
• Sampling Rate: Rate-based sampling (e.g., "0.1 samples per part")

To enter and view Sample Sets, open the Specs Dashboard:

Click on Sampling:

Create a New Sample Set

To enter a new Sample Set, click the +NEW SAMPLE SET button in the header:

Name the Sample Set, and enter Sample Ranges with corresponding Sample Counts for non-linear sampling:

Leave the highest range open-ended per the requirements for non-linear Sampling Sets:

• Must have a total range starting at one and ending at infinity (no maximum)
• Range segments must not overlap
• Each range must use either a sample count, or sampling rate. They are mutually exclusive

Based on each Batch size for the Parts where this Sample Set is applied, the required number of measurements will appear on your Workboards and in measurement dialogs as you work the Parts. The non-linear sampling assumption is that no matter how many Parts are treated in one batch, they will all be treated the same; so there is diminishing value in measuring the same property on individual Parts of the same Batch, unless required.

The Sample set you create and save will be available to be chosen when you apply Params to Spec Fields (create a Spec Field Assignment).

Assign a Sample Set

When you create or edit a Spec Field Parameter upon assignment to a Spec, you have the option, among others, to select an existing Sample Set:

You may choose instead to set a linear Sampling Rate, a Sample Count per Batch, or a timed Sampling Interval. See the Specs articles for more information.

Sample Sets can be incorporated with Part Number Specs, Specs on specific Work Orders, or Treatments.
