Gears are mechanical components that transmit torque and motion between rotating shafts, essential in various machines.

• Types of gears include spur gears, bevel gears, and worm gears.

• Spur gears are used in clocks and conveyor systems for simple motion transfer.

• Bevel gears are used in applications like hand drills to change the axis of rotation.

• Worm gears provide high torque and are commonly found in elevators and tuning

Cp and Cpk are statistical measures used to assess process capability in manufacturing and quality control.

• Cp (Process Capability) measures the potential capability of a process to produce output within specified limits.

• Cpk (Process Capability Index) measures how close a process is running to its specification limits, considering the mean.

• Cp is calculated as (USL - LSL) / (6 * sigma), where USL is the upper specificati...read more

PP and PPK are statistical measures used in process capability analysis to assess process performance and capability.

• PP (Process Performance) measures how well a process performs over time, considering variation.

• PPK (Process Performance Index) assesses how well a process meets specifications, accounting for process mean and variation.

• Example: A PP of 1.5 indicates a capable process, while a PPK of 1.0 suggests it may n...read more

Forging is a manufacturing process that shapes metal using compressive forces, enhancing its strength and durability.

• Types of forging include open-die forging, where metal is shaped between two flat dies.

• Closed-die forging involves shaping metal in a die that completely encloses it, allowing for more complex shapes.

• Roll forging is a continuous process that reduces the cross-section of a workpiece by passing it through ...read more
