Mixed Deck — All CPT Topics Flashcards

What is the purpose of a 'work order' in a production environment?

Answer: To authorize and provide instructions for the production of a specific quantity of product

A work order is a formal document that authorizes production and contains routing, quantities, materials, and specifications needed to complete a manufacturing job.

What should you do if you are exposed to hazardous chemicals?

Answer: Notify your supervisor and follow emergency procedures.

Immediately notifying your supervisor and following established emergency procedures is the correct action to take when exposed to hazardous chemicals. This ensures that appropriate safety protocols are initiated, such as seeking medical attention, containing the spill, or evacuating the area, to prevent further harm to yourself and others. Delaying action or attempting to handle it alone can exacerbate the situation and lead to more severe consequences.

In lean terminology, what is 'Takt time'?

Answer: The available production time divided by customer demand rate

Takt time synchronizes production pace with customer demand by dividing available production time by the number of units customers require.

In a production setting, what does a green safety color typically indicate on signs and equipment markings?

Answer: Safety information, first aid, or safe conditions

ANSI Z535 standards designate green for safety information, first aid equipment locations, and safe conditions.

Which communication method is best for documenting a recurring machine problem for future reference?

Answer: Written maintenance log or work order

A written log or work order creates a traceable record that maintenance and supervisors can reference to identify patterns and schedule repairs.

Why should equipment operators be trained to perform routine maintenance tasks?

Answer: To reduce downtime and increase equipment reliability.

Training equipment operators in routine maintenance empowers them to identify and address minor issues promptly, preventing them from escalating into major problems. This proactive approach significantly reduces unexpected equipment breakdowns and costly downtime, thereby increasing overall equipment reliability and lifespan.

A planner observes that actual cycle time consistently exceeds standard cycle time on one workstation. The most appropriate first step is to:

Answer: Investigate the root cause of the cycle time variance

Root cause analysis should precede any corrective action to ensure the solution addresses the actual problem rather than masking it.

Which tool is used to measure the inside diameter of a bore with high precision?

Answer: Bore gauge (telescoping gauge + micrometer)

A bore gauge (or telescoping gauge transferred to a micrometer) is the standard method for accurately measuring internal diameters.

What documentation practice is considered essential in Maintenance & Troubleshooting within the Certified Production Technician field?

Answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible

Real-time or near-real-time documentation in Maintenance & Troubleshooting ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.

What is the main advantage of using a warehouse management system (WMS) over manual paper-based tracking?

Answer: It provides real-time visibility into inventory location, quantity, and movement

A WMS delivers real-time data on inventory levels, locations, and transactions, enabling faster decisions, reduced errors, and improved order accuracy.

What does a high vibration reading in the axial direction on a rotating machine most likely indicate?

Answer: Misalignment

Axial vibration is a classic signature of shaft misalignment between coupled machines.

Under OSHA regulations, what is the employer's responsibility when an employee reports a safety hazard?

Answer: Investigate and correct the hazard within a reasonable timeframe

Employers are required to investigate reported hazards promptly and take corrective action within a reasonable timeframe to comply with OSHA's general duty clause.

In a 'pull' production system, manufacturing is triggered by:

Answer: Actual customer demand

Pull systems initiate production only when actual customer demand signals a need, reducing overproduction and excess inventory.

A torque wrench is used in final assembly and requires calibration. Who is responsible for ensuring it is calibrated before use?

Answer: The operator and the quality/maintenance system

Both the operator (to verify calibration status before use) and the quality/maintenance system (to schedule and perform calibration) share responsibility.

Why is it important to properly calibrate measurement tools in manufacturing?

Answer: To ensure the quality of the final product.

Properly calibrating measurement tools in manufacturing is essential to ensure the quality of the final product. Accurate measurements are critical for verifying that products meet design specifications and quality standards. Without calibrated tools, measurements can be unreliable, leading to the production of defective parts or products that do not function as intended, ultimately impacting customer satisfaction and increasing waste.

In lean manufacturing, which type of waste refers to overproducing more than what is immediately needed?

Answer: Overproduction

Overproduction — making more than is currently needed — is considered the worst of the seven wastes because it generates and hides all other types of waste.

A torque wrench used in final assembly must be calibrated. The calibration standard used is a torque analyzer with a stated accuracy of ±0.5%. The torque wrench being calibrated has a tolerance of ±4%. This calibration setup:

Answer: Meets the 4:1 TAR requirement since 4% ÷ 0.5% = 8:1 ratio

The TAR is 4% ÷ 0.5% = 8:1, which exceeds the minimum 4:1 requirement, making this calibration setup valid.

The primary purpose of a gage R&R study is to:

Answer: Evaluate the measurement system's contribution to total variation

Gage R&R (Repeatability and Reproducibility) quantifies how much of the observed variation comes from the measurement system itself versus actual part variation.

A production worker is required to enter a confined space with limited oxygen. What type of confined space classification applies?

Answer: Permit-required confined space

A confined space with an atmospheric hazard such as oxygen deficiency is classified as a permit-required confined space under OSHA 29 CFR 1910.146.

What is the purpose of a Kanban card in a lean production system?

Answer: To signal when materials or parts need to be replenished

Kanban cards serve as visual signals that trigger the movement, production, or supply of a specific item within a pull system.
