Different Parts of a Spec

Specification

A specification itself is home to a handful of different things such as:

1. Internal Description
2. External Description
3. Spec Fields (See below)
4. Associated Part Numbers and/or Treatments
5. Revision Control
6. Custom input fields
7. Default Processes including opt in/out and treatment selection

Specifications are commonly used to track the following types of documents:

1. Internal Processing Specs
2. Customer Supplied Specs
3. Industry Standard Specs
4. Material Manufacturer Specs

Spec Field and Spec Field Specs

A Spec Field is one of the most important building blocks for setting up the domain to collect data correctly. Getting these correct will be able to link like data together.

A Spec Field example is "Powder Coat Thickness". This field is likely of the type "NUMBER" and will be used for all specifications that reference a coating thickness for powder coated parts. Whether it is a customer spec, or internal processing spec they will both reference this singular spec field via spec field spec. The reason for having one spec field here is so that many specifications can be created and the same spec field ID is referenced in power tools and for reporting.

A Spec Field can have the follow field types:

1. Number
2. Boolean
3. Sensor
4. Datetime
5. Text
6. Timer

Each type will set up the parameter differently as we would collect different data.

A Spec Field Spec links a spec field and a spec together. An ID is created for the spec field spec but it also references the spec field id to tie in similar specifications. A spec field spec is unique to the specification that it falls under.

A spec field spec can be "generic". This means that if this spec & spec field spec is applied to a part and/or treatment, the parameters changed on the spec field spec will carry over to the part number. A non-generic spec field spec param will allow the user the ability to make unique values to the part number or treatment.

Spec Field Spec Params

Spec Field Spec Params are simply the values that fall under a spec field spec. These parameters are the metrics that we are collecting and certifying against. Depending on the type of the spec field, that will determine the type of data we are collecting (See above for Spec Field Types).

Within a parameter we will have a handful of values to set up. These will be common across all spec field types.

1. Parameter Name
2. Parameter Description
3. Input Requested or Required
4. Value must be passing
5. Request documentation
6. One at a time
7. Sampling rate per part or batch
8. Sample interval

Item 3 breakdown: If box for input requested is checked, then the operator will see that there is an input to be collected on the workboard/work order. They will be able to move past the measurement and process step without collecting a measurement. For input required, the operator will not be able to proceed processing until a measurement is gathered.

Item 4 breakdown: If this box is selected and the operator enters in a measurement that is outside the scope of the parameter, they will not be able to proceed in processing until a valid measurement is entered.

Item 5 breakdown: If this box is checked, the operator will be prompted to upload a file upon collected a measurement for the parameter. This can be used for general file uploads or image taking.

Item 6 breakdown: If this box is selected, the operator will be prompted to take multiple measurements based on the sampling rate. This is commonly used for thickness measurements where we need to gather a variable number of measurements, and we want to record each raw value.

Item 7 breakdown: Sampling rate per batch refers to how many measurements we must take per batch of parts we are processing. A common example is oven time for a rack of parts. We can gather 1 measurement that will be used for timing for all parts on the rack. Sampling rate per parts references how many measurements must be taken as a percentage of the total number of parts. If a value of 0.4 is entered here, the operator will be prompted to take 40 measurements from a quantity of 100 parts.

Item 8 breakdown: Sampling interval represents the frequency we must collect data to that parameter. For one time data collection, this attibute will be left empty. An example of this would be if we needed to perform a visual inspection every hour during a 10 hour processing cycle.

For Number Types:

1. Minimum value
2. Target Value
3. Maximum Value
4. Unit

For Timer Types:

1. Minimum value
2. Target Value
3. Maximum Value

For Sensors Types:

1. Sensor valid time
2. Sensor warning threshold
3. Minimum value - for Number Sensor Types
4. Target Value - for Number Sensor Types
5. Maximum Value- for Number Sensor Types

Note that for number sensor types the unit from the sensor type will be used for the parameter
