Cycle time is the total time to complete a process, while takt time is the available time per unit to meet customer demand.

• Cycle time is the time it takes to complete one cycle of a process, including both value-added and non-value-added activities.

• Takt time is the available time per unit to meet customer demand, calculated by dividing the available production time by the customer demand.

• Cycle time can be measured using a stopwatch or by analyzing historical data.

• Takt time he...read more

Heat treatment process involves heating and cooling metals to alter their physical and mechanical properties.

• Heat treatment is used to improve hardness, strength, toughness, and ductility of metals.

• Common methods include annealing, quenching, tempering, and normalizing.

• Annealing involves heating the metal to a specific temperature and then slowly cooling it to make it softer and more ductile.

• Quenching involves rapidly cooling the metal to increase its hardness.

• Tempering invol...read more

To convert AC current to DC current, a rectifier is used to change the direction of current flow.

• Use a rectifier to change the direction of current flow from alternating to direct

• Rectifiers can be half-wave or full-wave depending on the application

• Examples of rectifiers include diode rectifiers and bridge rectifiers

VCB stands for Vacuum Circuit Breaker, a type of circuit breaker that uses vacuum as the arc quenching medium.

• VCB is used to interrupt fault currents in electrical systems.

• Maintenance of VCB involves regular inspection of contacts, insulation resistance testing, and lubrication of moving parts.

• Cleaning of VCB contacts is essential to ensure proper operation and prevent arcing.

• Regular testing of VCB's operating mechanism is necessary to ensure reliability.

• VCB maintenance shoul...read more

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

PFMEA stands for Process Failure Mode and Effects Analysis, a technique used to identify and prioritize potential failure modes in a process.

• PFMEA helps in identifying potential failure modes in a process

• It assesses the severity, occurrence, and detection of each failure mode

• Risk priority numbers (RPN) are calculated to prioritize the failure modes for corrective actions

• Examples include identifying potential failures in manufacturing processes, healthcare procedures, or softw...read more

There are 5 phases of APQP: Planning, Product Design, Process Design, Product and Process Validation, and Feedback, Assessment, and Corrective Action.

Parts per million (ppm) is a unit of measurement used to describe the concentration of a substance in a solution.

• PPM is used to express very small concentrations of substances in a solution.

• 1 ppm is equivalent to 1 part of solute for every 1 million parts of solution.

• PPM is commonly used in environmental monitoring, water treatment, and chemical analysis.
