Spark Minda Maintenance Supervisor Interview Questions and Answers

Incremental encoder measures relative position changes while absolute encoder measures absolute position.

• Incremental encoder generates a series of pulses as the shaft rotates, which are used to determine the relative position change.

• Absolute encoder generates a unique digital code for each shaft position, providing absolute position information.

• Incremental encoder is simpler and less expensive, while absolute encoder i...read more

3ph induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

• Three-phase AC power is supplied to the stator winding, creating a rotating magnetic field.

• This rotating magnetic field induces a current in the rotor, which in turn creates its own magnetic field.

• The interaction between the stator and rotor magnetic fields causes the rotor to rotate, converting e

1 HP is equal to 746 watts.

• HP stands for horsepower, a unit of power used in the automotive and manufacturing industries.

• Watt is the SI unit of power.

• The conversion factor between HP and watt is 746.

Die casting and machining defects are common in manufacturing processes.

• Die casting defects include porosity, shrinkage, cold shuts, and flash.

• Machining defects include burrs, chatter marks, and tool marks.

• Die casting defects can be caused by improper temperature, pressure, or metal flow.

• Machining defects can be caused by dull tools, improper speeds and feeds, or poor fixturing.

• Defects can lead to part failure, reduced

Filling and high speed ratio formula is used to calculate the filling time of a container with a specific volume of liquid at a given flow rate.

• Filling and high speed ratio formula is V/Q

• V is the volume of the container and Q is the flow rate of the liquid

• The formula is used to determine the time it takes to fill a container with a specific volume of liquid at a given flow rate

• The higher the flow rate, the faster the c

I faced a defect in plastic commodity related to poor quality control during the manufacturing process.

• The defect was in the form of cracks and breakages in the plastic products.

• It was caused by inadequate monitoring and supervision during the molding and cooling stages.

• The defect resulted in a high number of rejected products and customer complaints.

• To address the issue, we implemented stricter quality control measure...read more

Maintenance refers to the process of ensuring the proper functioning and upkeep of equipment, machinery, or infrastructure.

• Maintenance involves regular inspections, repairs, and replacements to prevent breakdowns and extend the lifespan of assets.

• It includes tasks such as cleaning, lubricating, adjusting, and calibrating equipment.

• Maintenance can be preventive (scheduled maintenance to prevent failures) or corrective (...read more
