Steel Strips Wheels Interview Questions, Process, and Tips

An engine is a machine that converts energy into mechanical force or motion.

• Engines are used in various applications such as automobiles, aircraft, and power plants.

• They typically work by burning fuel to generate heat, which is then converted into mechanical energy.

• There are different types of engines, including internal combustion engines, steam engines, and electric engines.

• Examples of engines include car engines, je

A silencer is a device that reduces the noise produced by a machine or engine.

• Silencers are commonly used in automobiles to reduce the noise produced by the exhaust system.

• They work by using a series of chambers and baffles to absorb and dissipate sound waves.

• Silencers are also used in firearms to reduce the noise of the gunshot.

• They are typically made of metal and can be attached to the end of the barrel.

• Silencers are...read more

A thermostat is a device that regulates temperature by turning heating or cooling systems on or off.

• Thermostat is used to maintain a desired temperature in a room or a building.

• It works by sensing the temperature and then turning the heating or cooling system on or off accordingly.

• Thermostats can be manual or programmable, with the latter allowing users to set different temperatures for different times of the day.

• Examp...read more

The temperature at which a thermostat valve opens depends on the specific application and type of valve.

• Thermostat valves can open at different temperatures depending on the application.

• The opening temperature can range from below freezing to several hundred degrees Fahrenheit.

• The type of valve, such as a wax pellet or bimetallic strip valve, can also affect the opening temperature.

• For example, a thermostat valve in a ...read more

Different types of casting include sand casting, investment casting, die casting, and continuous casting.

• Sand casting involves pouring molten metal into a sand mold

• Investment casting uses a wax pattern that is coated in ceramic and then melted out to create a mold

• Die casting involves injecting molten metal into a mold under high pressure

• Continuous casting is used for producing long lengths of metal with a constant cros

Casting is a manufacturing process in which a liquid material is poured into a mold and allowed to solidify.

• Casting is used to create complex shapes that would be difficult or impossible to make using other methods.

• The liquid material used for casting can be metal, plastic, or even concrete.

• The mold used for casting can be made of various materials, including sand, plaster, and ceramic.

• After the material has solidified...read more

VFD stands for Variable Frequency Drive, which controls the speed of an AC motor by varying the frequency and voltage of the power supplied to it.

• VFDs convert fixed frequency AC power to variable frequency AC power

• They control motor speed by adjusting the frequency of the power supplied

• VFDs can improve energy efficiency and reduce wear and tear on motors

• Common applications include HVAC systems, pumps, and conveyor belt

A servo drive is an electronic amplifier used to power and control servo motors in automation systems.

• Converts low-power control signals into high-power signals to move the servo motor

• Provides precise control over speed, position, and torque of the motor

• Commonly used in robotics, CNC machines, and industrial automation

• Helps in achieving accurate and repeatable motion control

PLC stands for Programmable Logic Controller. There are various types of PLCs available in the market, each with its own unique features and capabilities. Some common types include modular PLCs, compact PLCs, and rack-mounted PLCs. There are also different software programs used to program and control PLCs.

• Types of PLCs include modular PLCs, compact PLCs, and rack-mounted PLCs

• Common software programs for PLC programmin...read more

OEE stands for Overall Equipment Effectiveness and is a measure of how well a manufacturing process is performing.

• OEE is calculated by multiplying Availability, Performance, and Quality.

• Availability is the ratio of operating time to planned production time.

• Performance is the ratio of actual production to maximum possible production.

• Quality is the ratio of good parts to total parts produced.

• OEE = Availability x Performa...read more

G code and M code are machine codes used in CNC programming to control the movements and functions of a machine tool.

• G code is used to control the movements of the machine, such as linear or circular interpolation.

• M code is used to control auxiliary functions of the machine, such as turning on or off coolant or spindle rotation.

• G codes are typically used for positioning and feed rate control, while M codes are used for...read more

I have used software to create programs.

• I have used software like AutoCAD, SolidWorks, and MATLAB to create programs for production engineering.

• Using software allows for more precise and efficient programming compared to manual methods.

• Software also helps in simulating and testing programs before implementation.

The base of planning is setting clear goals and objectives.

• Setting specific, measurable, achievable, relevant, and time-bound (SMART) goals

• Identifying resources needed to achieve the goals

• Creating a timeline for completion

• Regularly monitoring progress and making adjustments as needed
