Dimensional Evaluator SSBO

The primary responsibility of this job will be rework grinding, with the expectation of performing Visual/Dimensional Inspection as directed.

To identify and correct visual / dimensional flaws in castings to insure the final product meets customer specifications. Based on business needs, may be required to perform the functions of visual / dimensional inspection, straightening, and CMM evaluation/disposition (along with their associated tasks i.e. hardness testing, UTT, targeting, etc.) as defined on PCC Technique Cards, blueprints and other documentation/work instructions.

The aim of this description is to recognize multi-skilled work which facilitates the flow of parts. Instead the multiple tasks are performed on the parts by a single employee. Each employee is expected to apply an average of 20 percent of their total hours worked, performing on one or more secondary functions in addition to a primary “core” function.

• If your primary “core function” is visual dimensional inspection, then the secondary function of straightening and/or CMM evaluation/disposition must be performed a minimum of 20% of the time.
• If your primary “core function” is straightening, then the secondary function of visual dimensional inspection and/or CMM evaluation/disposition must be performed a minimum of 20% of the time.

Objective: to review inspection paperwork, and grind and blend defect areas on castings; to blend welds to blueprint tolerances.

Essential Job Functions:

• Reviews x-ray/inspection paperwork, sketches and blueprints to determine grinding requirements.
• Removes surface and blind cavity defects from castings using rotary files, burrs, abrasives or belts to prepare castings for repair.
• Blends and reworks repaired areas to specified tolerances; may use hand-held sandblaster.

Objective: to visually and dimensionally inspect castings in accordance with customer specifications and to ensure that only necessary rework is performed.

Essential Job Functions:

• Follows Quality Systems and Technique Card requirements.
• Fixtures some parts and leaves others freestanding.
• Visually inspects castings as required.
• Dimensionally inspects castings for conformance to blueprint and Technique Card specifications using templates, micrometers, fixtures, gauges, calipers, ultrasound, boroscope and other dimensional measuring devices.
• Checks casting hardness using Brinell, Rockwell and other instruments.
• Marks castings to identify area needing rework, mill rates, etc. in order to meet dimensional and visual specifications.
• Adjusts fixtures, gauges and precision measuring tools to calibrated standards.

Objective: to straighten castings to meet dimensional tolerances and customer specifications.

Essential Job Functions:

• Sets up castings on surface plates or fixtures.
• Evaluates the condition of parts using precision measuring tools to determines the most effective method of straightening castings.
• Establishes datums to casting surfaces and fixtures on surface plates straightens to a rotational tolerance.
• Straightens casting to the required configuration using a variety of tools and devices, including presses, straightening fixtures, profile templates, and power or manual tools.

Objective: to review CMM Reports and determine using Technique Card Hit Maps and customer specifications if castings are in accordance with customer specifications and to ensure that only necessary rework is performed.

Essential Job Functions:

• Reviews CMM Reports for discrepancies.
• Evaluate the CMM BT (Before Target) report and utilizing Localized Alignment Values (LAV) establish rest point values for targeting.
• Determine if discrepancies are acceptable to customer specification and/or applicable part specific requirements.
• Evaluate discrepant part/s using standard Visual/Dimensional Inspection techniques to determine necessary rework to reprocess part/s back to customer specification.
• Marks castings to identify area/s needing rework in order to meet specifications.
• Routes discrepant part/s to the Rework Analyst for reprocessing.
