Poka yoke is a Japanese term for mistake-proofing or error-proofing.

• It is a technique used to prevent errors from occurring during a process.

• It involves designing a process or product in a way that makes it impossible or difficult to make mistakes.

• Examples include using color coding, shapes, or sensors to prevent errors.

• Poka yoke can improve quality, reduce costs, and increase efficiency.

CAPA stands for Corrective and Preventive Action. It is a process used to identify, investigate, and resolve quality issues.

• CAPA is a quality management system tool used to address and prevent problems

• It involves identifying the root cause of a problem and implementing corrective and preventive actions

• CAPA is an ongoing process that requires continuous monitoring and improvement

• Examples of CAPA include implementing new...read more

Scrap refers to any material or product that is deemed unusable or defective.

• Scrap can be generated during manufacturing processes when a product does not meet quality standards.

• It can also refer to excess or leftover materials that cannot be used in production.

• Scrap can be recycled or sold for its raw materials.

• Examples of scrap include defective parts, excess packaging materials, and leftover metal shavings.

Vernier caliper and micrometer are both precision measuring instruments, but they differ in their design and measurement range.

• Vernier caliper measures both internal and external dimensions with a range of 0-150mm or 0-6 inches.

• Micrometer measures thickness or outside dimensions with a range of 0-25mm or 0-1 inch.

• Vernier caliper uses a sliding scale and a vernier scale for measurement, while micrometer uses a screw mec...read more

PPM stands for parts per million. It is a unit of measurement used to express the concentration of a substance in a solution.

• PPM is calculated by dividing the number of parts of a substance by the total number of parts in the solution and multiplying by one million.

• Formula: PPM = (Number of parts of substance / Total number of parts in solution) * 1,000,000

• For example, if there are 10 parts of a substance in a solution...read more

The seven QC tools are a set of quality control tools used to identify and solve quality-related issues in manufacturing processes.

• The seven QC tools are: check sheets, histograms, Pareto charts, cause-and-effect diagrams, control charts, scatter diagrams, and flowcharts.

• Check sheets are used to collect data and record occurrences of specific events or defects.

• Histograms are graphical representations of data distributi...read more
