GD&T is a symbolic language used to specify the geometric tolerances of a part. Least material count is the minimum amount of material required to meet the design requirements. Angularity is the tolerance for the angle between two surfaces.

• GD&T stands for Geometric Dimensioning and Tolerancing

• It is used to define the allowable variation in form, size, orientation, and location of features on a part

• Symbols are used to represent the geometric tolerances on a drawing

• Least materi...read more

MIG and MAG welding differ in the type of shielding gas used. CO2 is preferred over Argon due to its cost-effectiveness. Efficiency depends on the application.

• MIG welding uses a mixture of Argon and CO2, while MAG welding uses pure CO2

• CO2 is preferred over Argon due to its lower cost and higher penetration power

• Efficiency of the mixture depends on the application and the type of metal being welded

• For example, a higher percentage of CO2 is used for welding thicker metals

• Effici...read more

Explanation of 8D, A3, action plan and demonstration of an action plan using pen and paper and 7QC tools.

• 8D is a problem-solving methodology used to identify, correct and prevent recurring problems.

• A3 is a structured problem-solving approach that uses a single sheet of paper to document the problem, analysis, and solution.

• An action plan is a detailed plan outlining actions needed to achieve a specific goal or objective.

• To demonstrate an action plan, identify a problem, define...read more

OEE stands for Overall Equipment Effectiveness and PPM stands for Parts Per Million.

• OEE is a metric used to measure the productivity of a manufacturing process.

• It takes into account three factors: availability, performance, and quality.

• PPM is a measure of the number of defective parts per million produced.

• It is commonly used in quality control and Six Sigma methodologies.
