7 QC is a set of quality control tools used in manufacturing to identify and solve production problems.

• 7 QC stands for Seven Quality Control tools

• These tools include Pareto analysis, cause-and-effect diagram, check sheet, control chart, histogram, scatter diagram, and flowchart

• They are used to analyze data, identify root causes of problems, and make informed decisions for process improvement

PPL stands for Production Per Labour and PPLH stands for Production Per Labour Hour.

• PPL is a measure of how much production is achieved per unit of labor input.

• PPLH is a measure of how much production is achieved per labor hour.

• Both metrics are used to evaluate the efficiency of production processes.

• For example, if a factory produces 100 units with 10 workers, the PPL would be 10 units per worker.

• If the same factory op...read more

Friction is the resistance encountered when two surfaces slide against each other, affecting motion and energy efficiency.

• Friction can be static (preventing motion) or kinetic (resisting motion).

• Static friction is what keeps an object at rest until a certain force is applied.

• Kinetic friction occurs when two surfaces are sliding against each other, like a sled on snow.

• Friction is influenced by the materials in contact; ...read more

Diagnosing and resolving machine breakdowns involves systematic troubleshooting and effective communication.

• Identify the symptoms: Check for unusual noises, vibrations, or error codes.

• Gather information: Consult machine logs and maintenance records for previous issues.

• Isolate the problem: Use diagnostic tools to pinpoint the faulty component, such as a multimeter for electrical issues.

• Implement a solution: Replace or r...read more

Pneumatic circuits use compressed air for power, while hydraulic circuits use pressurized liquids for force transmission.

• Pneumatic circuits are commonly used in automation systems, like conveyor belts.

• Hydraulic circuits are often found in heavy machinery, such as excavators.

• Pneumatics are generally faster and cleaner, while hydraulics provide more force.

• Examples of pneumatic tools include air drills and impact wrenches...read more
