KOIS Interview Questions and Answers

To improve cycle time, focus on process optimization and efficiency. Rejection control involves identifying root causes of defects and implementing corrective actions.

• Implement lean manufacturing principles to streamline processes and reduce waste

• Utilize automation and technology to speed up production

• Regularly analyze data and performance metrics to identify bottlenecks and areas for improvement

• Train employees on best practices and quality standards to reduce errors and defe...read more

OEE stands for Overall Equipment Effectiveness, a measure of how well a manufacturing process is utilized.

• OEE is calculated by multiplying Availability, Performance, and Quality percentages.

• Availability = (Operating Time / Planned Production Time) * 100

• Performance = (Ideal Cycle Time / Total Count) * 100

• Quality = (Good Count / Total Count) * 100

• OEE = Availability * Performance * Quality

• For example, if a machine operates for 8 hours out of a planned 10 hours, with an ideal cyc...read more

Rework analysis involves identifying and addressing issues in a product or process to improve efficiency and quality.

• Rework analysis is a process of examining and evaluating the reasons for rework in a project or product.

• It involves identifying root causes of defects or errors and implementing corrective actions to prevent future rework.

• Examples of rework analysis include conducting failure mode and effects analysis (FMEA) to identify potential failure modes and their causes,...read more

Lean manufacturing is a production method aimed at minimizing waste and maximizing efficiency.

• Focuses on continuous improvement

• Eliminates waste in processes

• Involves just-in-time production

• Uses tools like value stream mapping and 5S

• Promotes employee involvement and empowerment

Autonomous maintenance is a maintenance strategy where operators are responsible for routine maintenance tasks.

• Autonomous maintenance involves operators taking ownership of basic maintenance tasks such as cleaning, lubricating, and inspecting equipment.

• The goal of autonomous maintenance is to prevent breakdowns and improve overall equipment effectiveness.

• Operators are trained to identify abnormalities and address them before they lead to more serious issues.

• Autonomous mainten...read more

Scrap count refers to the number of defective or unusable parts produced during manufacturing.

• Scrap count is an important metric in manufacturing to track quality control and efficiency.

• It helps identify areas of improvement in the production process.

• Examples of scrap count include parts with manufacturing defects, incorrect dimensions, or damaged during production.
