10+ Kasiga School Interview Questions and Answers

Different operations on a lathe machine include turning, facing, drilling, boring, threading, and tapering.

• Turning: Removing material from the outer diameter of a workpiece to create a cylindrical shape.

• Facing: Cutting the end of a workpiece to create a flat surface.

• Drilling: Creating holes in the workpiece using a drill bit.

• Boring: Enlarging existing holes or creating larger cylindrical holes.

• Threading: Cutting threads on the surface of a workpiece to create a screw-like sha...read more

G code and M code are programming languages used in CNC machining to control the movements and functions of the machine.

• G code is used to control the movements of the machine, such as positioning, feed rate, and spindle speed.

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

• Program writing involves creating a sequence of G and M codes to instruct the CNC machine on how to produce a specific part.

• Example: G01 X1 Y1 F2...read more

Degree of freedom refers to the number of independent variables or parameters that can be varied in a system without changing its state.

• Degree of freedom is the number of variables that can be changed independently without affecting the overall system.

• In engineering, it often refers to the number of directions in which a mechanical system can move freely.

• For example, a simple pendulum has one degree of freedom because it can only move back and forth along one axis.

• A car movin...read more

There are 1000 millimeters in one meter.

• 1 meter is equal to 1000 millimeters.

• The prefix 'milli-' denotes one thousandth of a unit.

• For example, if you have a length of 2 meters, it would be equivalent to 2000 millimeters.

Production and manufacturing involve the process of creating goods or products through various methods and techniques.

• Production involves the actual creation of goods or products using raw materials and machinery.

• Manufacturing is the process of converting raw materials into finished products through various stages like processing, assembly, and packaging.

• Quality control is an essential aspect of production and manufacturing to ensure that the final products meet the required ...read more

Engineering plastics are a group of materials with superior mechanical properties, chemical resistance, and dimensional stability.

Manufacturing instruments are tools used in the production process to ensure quality and efficiency.

• Calipers - used for measuring dimensions of objects

• Micrometer - used for precise measurements

• Gauge blocks - used for calibration

• Spectrophotometer - used for analyzing materials

• CMM (Coordinate Measuring Machine) - used for dimensional measurements

Operations such as cutting, drilling, shaping, and finishing can be performed on both CNG machine and lathe machine.

• Cutting: Both machines can be used for cutting materials such as metal or plastic.

• Drilling: Holes can be drilled using both machines.

• Shaping: Both machines can shape materials into desired forms.

• Finishing: Both machines can be used for finishing processes like polishing or sanding.

• Examples: Turning a metal rod on a lathe machine, cutting threads on a CNG machine...read more

PET polymer, also known as polyethylene terephthalate, is a type of plastic commonly used in packaging and textiles.

• PET is a thermoplastic polymer that is lightweight, strong, and transparent.

• It is commonly used in the production of water bottles, food containers, and polyester fibers.

• PET can be easily recycled and is one of the most recycled plastics worldwide.

• It has a high melting point, making it suitable for hot-fill applications.

• PET is also used in the medical field for ...read more
