Mixed Deck — All CMS Topics Flashcards

In the DMAIC problem-solving methodology, the 'Analyze' phase primarily focuses on:

Answer: Identifying and verifying root causes of defects

The Analyze phase uses data and statistical tools to identify and validate the root causes that drive the problem identified in Define/Measure.

Which document formally describes the quality-related activities, resources, and responsibilities for a specific product or project?

Answer: Quality plan

A quality plan specifies quality practices, resources, and activities tailored to a particular product, project, or contract.

A manufacturing facility stores 10,000 gallons of oil above ground. Which federal regulation requires them to have a Spill Prevention, Control, and Countermeasure (SPCC) plan?

Answer: Clean Water Act Section 311

Clean Water Act Section 311 and the SPCC rule (40 CFR Part 112) require facilities storing more than 1,320 gallons of oil above ground to have an SPCC plan.

What is the primary purpose of a cost-volume-profit (CVP) analysis?

Answer: To understand how changes in costs and volume affect profitability

CVP analysis examines the relationship between costs, sales volume, and profit to support pricing, production, and planning decisions.

Which honing process characteristic distinguishes it from grinding?

Answer: Honing uses abrasive stones with reciprocating and rotating motion at low speed to improve bore geometry

Honing uses bonded abrasive stones that simultaneously rotate and reciprocate at relatively low speeds, primarily improving bore geometry, surface finish, and size accuracy.

In the context of production scheduling & capacity planning, what role does continuous professional development play for CMS practitioners?

Answer: It ensures practitioners remain current with evolving standards, technologies, and best practices

Continuous professional development is essential in production scheduling & capacity planning because it ensures CMS practitioners remain current with evolving standards, technologies, and best practices, maintaining competency throughout their careers.

In metrology, what is 'measurement uncertainty'?

Answer: A quantified range within which the true value is estimated to lie with a stated confidence level

Measurement uncertainty is a quantified estimate of the dispersion of values that could reasonably be attributed to the measured quantity, expressed with a confidence level.

When analyzing a value stream map, 'push' production arrows indicate what condition?

Answer: Material flows based on a forecast or schedule regardless of downstream need

Push arrows on a VSM show that work is moved forward based on schedules or forecasts rather than actual downstream consumption, often creating excess WIP.

When documenting activities related to automation & industrial robotics, which practice is considered essential for CMS certification holders?

Answer: Maintaining comprehensive records that include procedures, observations, results, and any anomalies

Comprehensive documentation that includes procedures, observations, results, and any anomalies is essential in automation & industrial robotics. This supports quality assurance, enables peer review, and satisfies regulatory and audit requirements.

In the context of manufacturing cost analysis, what role does continuous professional development play for CMS practitioners?

Answer: It ensures practitioners remain current with evolving standards, technologies, and best practices

Continuous professional development is essential in manufacturing cost analysis because it ensures CMS practitioners remain current with evolving standards, technologies, and best practices, maintaining competency throughout their careers.

A manufacturer needs a material with high strength-to-weight ratio for aerospace components. Which material family is most appropriate?

Answer: Titanium alloys

Titanium alloys offer exceptional strength-to-weight ratios and corrosion resistance, making them the preferred choice for aerospace structural components.

Which statistical tool is used to determine whether a measurement process is capable of distinguishing between parts within the process tolerance?

Answer: Gauge R&R study with number of distinct categories (ndc)

The number of distinct categories (ndc) from a Gauge R&R study indicates how many groups within the process variation the measurement system can reliably distinguish; ndc ≥ 5 is required.

Which inventory valuation method results in the highest cost of goods sold during a period of rising prices?

Answer: LIFO (Last-In, First-Out)

Under LIFO, the most recently purchased (higher-cost) inventory is charged to COGS first, maximizing cost of goods sold when prices are rising.

In resistance spot welding, the nugget (weld zone) forms primarily at the:

Answer: Faying surface (interface between the two sheets being joined)

Contact resistance is highest at the faying surface (sheet-to-sheet interface), concentrating heat generation there and causing the nugget to form at that location.

What does the acronym SCADA stand for in industrial manufacturing systems?

Answer: Supervisory Control and Data Acquisition

SCADA stands for Supervisory Control and Data Acquisition, an industrial control system used to monitor and control manufacturing equipment and processes remotely.

Which alloying element is added to steel to improve its machinability by forming soft inclusions that act as chip breakers?

Answer: Sulfur

Sulfur forms manganese sulfide (MnS) inclusions in steel that act as internal lubricants and chip breakers, significantly improving machinability.

In additive manufacturing, what is the primary limitation of Fused Deposition Modeling (FDM) compared to Selective Laser Sintering (SLS)?

Answer: FDM produces parts with visible layer lines and anisotropic mechanical properties due to the layer-by-layer extrusion method

FDM's layer-by-layer extrusion creates visible stair-stepping, anisotropic strength (weaker in the Z-direction), and may require support structures for overhanging features.

Which routing strategy is used to determine the most efficient sequence of stops for a delivery vehicle serving multiple customers?

Answer: Vehicle Routing Problem (VRP) optimization

The Vehicle Routing Problem (VRP) is an optimization technique that determines the most cost-effective routes and stop sequences for a fleet of delivery vehicles.

In the context of product lifecycle management (PLM), what is the 'end-of-life' (EOL) phase?

Answer: The phase when a product is discontinued and production, support, or sales are terminated

The EOL phase marks the formal discontinuation of a product, requiring decisions about inventory rundown, customer support transition, and disposal or recycling of remaining stock.

What is the primary goal of total productive maintenance (TPM)?

Answer: To reduce machine breakdowns and increase productivity.

The primary goal of Total Productive Maintenance (TPM) is to maximize equipment effectiveness by eliminating breakdowns, minor stops, and defects through a comprehensive system involving all employees. TPM focuses on proactive and preventive maintenance to ensure machines are always in optimal working condition. This approach significantly reduces downtime, increases productivity, and improves overall equipment efficiency.
