SS Industries Interview Questions and Answers

Explanation of polymorphism, function overloading/overriding, virtual function, and friend function.

• Polymorphism is the ability of an object to take on many forms.

• Function overloading is having multiple functions with the same name but different parameters.

• Function overriding is having a derived class provide its own implementation of a method that is already provided by its parent class.

• Virtual functions are functions...read more

Temperature and irradiance affect the performance and efficiency of solar panels.

• High temperatures can decrease the efficiency of solar panels.

• Increased irradiance levels can lead to higher power output.

• Temperature coefficient determines the panel's performance at different temperatures.

• Irradiance levels vary based on factors like time of day, weather conditions, and panel orientation.

• Temperature and irradiance should

Co-generation plants produce both electricity and heat. They can be linked with solar PV plants to increase energy efficiency.

• Co-generation plants use a single fuel source to produce both electricity and heat

• Solar PV plants generate electricity from sunlight

• Linking co-generation plants with solar PV plants can increase overall energy efficiency

• Excess heat from co-generation plants can be used to power solar thermal sys...read more

Grinding is a process of removing material from a workpiece using a grinding wheel. Multi-point cutting tools are tools with multiple cutting edges.

• Grinding is commonly used in manufacturing to achieve tight tolerances and smooth finishes.

• Multi-point cutting tools are used in machining operations to remove material from a workpiece.

• Examples of multi-point cutting tools include drills, end mills, and reamers.

• The number ...read more

5S, Kaizen, and 7QC tools are methodologies used in manufacturing to improve efficiency and quality.

• 5S is a workplace organization method that involves sorting, simplifying, sweeping, standardizing, and sustaining.

• Kaizen is a continuous improvement philosophy that involves making small, incremental changes to processes and systems.

• 7QC tools are a set of quality control tools used to identify and solve problems, includi...read more

Grinding defects are common in manufacturing processes and can include chatter marks, burn marks, and surface cracks.

• Chatter marks are caused by vibration during grinding and appear as a series of regular marks on the workpiece.

• Burn marks are caused by excessive heat during grinding and appear as discolored areas on the workpiece.

• Surface cracks can be caused by a variety of factors, including improper grinding techniqu...read more

Plunge grinding and through feed grinding are two types of grinding processes used in manufacturing.

• Plunge grinding involves grinding a part by plunging it into the grinding wheel, creating a flat or tapered surface.

• Through feed grinding involves feeding the part through the grinding wheels, creating a straight and smooth surface.

• Plunge grinding is typically used for parts with complex shapes or contours, while through...read more

Kanban is a lean manufacturing system that uses visual cues to signal the need for production or movement of materials.

• Kanban originated in Japan as a way to improve manufacturing efficiency.

• It involves using cards or other visual cues to signal when materials or products are needed.

• Kanban is often used in conjunction with just-in-time (JIT) manufacturing.

• It can also be applied to other industries, such as software dev...read more
