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 (F...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.

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 operate...read more

Production loss can be managed by identifying root causes, implementing preventive measures, optimizing processes, and continuously monitoring performance.

• Identify root causes of production loss through root cause analysis

• Implement preventive measures such as regular maintenance, training programs, and quality control checks

• Optimize processes by streamlining workflows, improving efficiency, and reducing waste

• Continuous...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.
