The engine is a machine that converts fuel into mechanical energy to power vehicles, machines, or equipment.

• Converts fuel into mechanical energy

• Powers vehicles, machines, or equipment

• Can be internal combustion engine or electric motor

A wire bonding machine is a tool used in semiconductor manufacturing to connect wires to semiconductor devices.

• Wire bonding machines use heat, pressure, and ultrasonic energy to bond wires to semiconductor devices.

• There are different types of wire bonding machines, such as ball bonding and wedge bonding machines.

• Wire bonding is a crucial step in the production of integrated circuits and other semiconductor devices.

Tolerance refers to the acceptable range of variation in a physical dimension or property of a material or product.

• Tolerance is the difference between the maximum and minimum limits of a dimension or property.

• It ensures that parts fit together properly and function as intended.

• Tolerance can be specified as a numerical value or a range, such as +/- 0.1mm.

• Examples include the tolerance for the diameter of a shaft or the

The least count of a micrometer is the smallest measurement that can be read on the scale.

• The least count of a micrometer is typically 0.01mm or 0.001mm depending on the type of micrometer.

• It is determined by the number of divisions on the thimble and the main scale.

• For example, a micrometer with 50 divisions on the thimble and a main scale reading in mm will have a least count of 0.01mm.

A jig is a type of tool used to control the location and/or motion of another tool. A fixture is a work-holding or support device used in the manufacturing industry.

• Jigs are used to guide cutting tools, while fixtures are used to hold workpieces in place during machining operations.

• Jigs and fixtures are commonly used in manufacturing processes such as welding, drilling, and milling.

• Examples of jigs include drill jigs, ...read more

Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's Law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• It is named after German physicist Georg Simon Ohm, who first formulated the law in 1827.

• Ohm's Law is fundamental in the field of electrical engineering and is used to analyze

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

• Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.

• Transf...read more

Motors convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy.

• Motors use electricity to produce motion, while generators use motion to produce electricity

• Motors have a rotor that spins within a stator, while generators have a rotor that is turned by an external force

• Examples of motors include electric fans and washing machines, while examples of generators in

TIG welding uses a tungsten electrode to create a precise and clean weld, while MIG welding uses a consumable wire electrode and shielding gas.

• TIG welding is slower but produces higher quality welds with less spatter and distortion.

• MIG welding is faster and better suited for thicker materials and high-volume production.

• TIG welding requires more skill and experience, while MIG welding is easier to learn and use.

• TIG weld...read more

Five major losses in industrial work are downtime, defects, inefficiency, waiting, and overproduction.

• Downtime: Refers to the time when production is halted due to equipment breakdown, maintenance, or other issues.

• Defects: Occur when products do not meet quality standards and need to be reworked or discarded.

• Inefficiency: Waste of resources, such as excessive energy consumption or poor utilization of manpower.

• Waiting: ...read more

A CNC machine is a computer-controlled machine tool used for precision machining.

• CNC stands for Computer Numerical Control.

• It uses pre-programmed instructions to control the movement of the machine.

• CNC machines are widely used in manufacturing industries for tasks like cutting, drilling, milling, and turning.

• They offer high precision, repeatability, and automation.

• Examples of CNC machines include CNC mills, lathes, rou

The electrode used in MIG welding is a consumable wire electrode.

• MIG welding stands for Metal Inert Gas welding.

• The electrode is continuously fed through a welding gun and melts to form the weld.

• The wire electrode is made of the same material as the base metal being welded.

• The shielding gas used in MIG welding protects the weld from atmospheric contamination.

• Common types of wire electrodes include ER70S-6 for mild stee
