FMEA Control Plans Table
Control plans are part of the FMEA module. To use them, you must turn on the FMEA Control Plans table in the Project properties. For more information, see Table Settings (Project). Once you close the System file and open it again, the FMEA Control Plans pane is shown in the lower window or right window, depending on the System file orientation. To switch between the horizontal and vertical orientations, you can select View > Split Windows Vertically.
By default, the FMEA Control Plans table displays all control plans that are inserted for the active FMEA. However, you can use Filter By commands to limit the records that are shown in this table. For more information, see ‘Filter by’ Commands for FMEA Control Plan and DVP Tables.
The Table Format file for the FMEA Control Plans table determines the data fields that appear. The following table describes the fields that are shown by default. You can insert any of the other fields available for this table. For more information, see Table Format Files.
Field
Description
Machine/Device/Tool
The processing equipment for each operation, described as precisely as possible. For example, you can enter the name, manufacturer, model number, serial number, and asset number.
Control Plan Identifier
The unique identifier assigned to the control plan. While an identifier is assigned to the control when it is inserted, you can change it to any unique value. The format for the assigned identifier is specified by FMEA Control Plans Identifier, which appears under Identifiers in the System file properties. This property appears only when control plans are shown in the System file. For more information, see Identifiers System File Properties. If process flow diagrams or FMEAs are available, you can enter a cross reference number in this column.
Product Characteristics
The features or properties of a part, component, or assembly that are described on drawings, shop practice standards, or other primary engineering documents. You enter a compilation of all important product characteristics from all sources in this field. While a control plan must list all special characteristics, it can also list other product characters for process controls that are routinely tracked during normal operation.
Process Characteristics
The process (input) variables that have cause-and-effect relationships with the identified product characteristics. A process characteristic can be measured only at the time it occurs. Examples include the voltage setting for a weld machine, air pressure setting for a paint gun, and force setting for a torque wrench. You enter process characteristics for variations that must be controlled to minimize product variation. You can have multiple process characteristics for each product characteristic. In some processes, one process characteristic can affect several product characteristics.
Characteristic Class
Indicates the importance of the characteristic and allows characteristics to be grouped by severity. Default choices are A, B, C, and D.
Specification/Tolerance
The specifications and tolerances, which can be obtained from various engineering documents, such as drawings, shop practices standards, welding standards, and work instructions.
Evaluation Method
The measurement systems for gauges, fixtures, tools, and test equipment that are used to measure a part or process. Prior to relying on a measurement system, analyze its linearity, reproducibility, repeatability, stability, and accuracy. When dedicated gauges are used, reference gauge numbers.
Sample Size
The sample size when sampling is required.
Sample Frequency
The corresponding frequency when sampling is required.
Control Method
A description of how the operation is controlled, including work instruction numbers where applicable. You want to base control method selection on effective analysis of the process. Methods for controlling operation include statistical process controls, inspections, attribute data, mistake-proofing (automated or non-automated), and sampling plans. You want control plan descriptions to reflect the planning and strategy being implemented in the manufacturing process. If elaborate control procedures are used, the plan typically references the work instruction by its work instruction number. You want to continually evaluate the method to determine how effectively it controls the process. For example, if significant changes in the process or process capability occur, you need to evaluate the control method.
Reaction Plan
The corrective actions necessary to avoid either producing non-conforming product or operating out of control. These actions are typically the responsibility of the people closest to the process, such as operators, job setters, and supervisors. You want to document non-conformities per company procedure and note responsible parties. In all cases, suspect and non-conforming products must be identified and quarantined so that they can be disposed of as designated in the reaction plan. If a specific reaction plan or work instruction number exists, reference it and identify the person responsible for this document.
References
Any documents or drawings to add as attachments. This field is an Attachments field. All files specified in it are copied into the Attachments folder. For more information, see Inserting and Modifying Attachments.
Clicking < Click here to insert a new record > in the last row inserts a control plan that is not associated with any other record. When the special Controls field is inserted in the FMEA Tree Items table and FMEA Worksheet table, you can use it to not only associate records with one or more existing control plans but also to insert new control plans that are automatically associated with this record. For more information, see Inserting Control Plans.
You can embed the FMEA Control Plans table on a FMEA Tree Items or FMEA Worksheet form. In the embedded table, only the control plans associated with the selected record on the form are shown. Inserting a new control plan in the embedded table automatically associates it with the selected record. For more information, see Embedded Tables on Forms.
The FMEA Control Plan table supports 15 subtables. All of these tables support aggregate functions for user-defined FMEA calculations. For more information, see Control Plan User-Defined Calculations.
You can import data into or export it from the FMEA Control Plans table. For general information, see Importing and Exporting. You can also import and export data for the Controls field in the FMEA Tree Items or FMEA Worksheet table to create associations. For fields in the Global Attributes table, you can only export data.
