Alkem Laboratories Diploma Engineer Trainee - DET Interview Questions, Process, and Tips

CNC stands for Computer Numerical Control.

• CNC is a manufacturing process that uses computerized control systems to operate machine tools.

• It involves the use of pre-programmed software to control the movement of tools and machinery.

• CNC machines are widely used in industries such as automotive, aerospace, and electronics.

• Examples of CNC machines include CNC mills, lathes, routers, and plasma cutters.

5S is a workplace organization method that aims to improve efficiency and productivity by maintaining cleanliness and orderliness.

• 5S stands for Sort, Set in Order, Shine, Standardize, and Sustain.

• Sort involves removing unnecessary items from the workplace.

• Set in Order involves organizing the remaining items in a logical and efficient manner.

• Shine involves cleaning and maintaining the workplace.

• Standardize involves crea...read more

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

• The least count of a vernier caliper is typically 0.02 mm or 0.001 inches.

• The least count of a micrometer is typically 0.01 mm or 0.0001 inches.

• The least count is determined by the number of divisions on the scale and the pitch of the screw.

• The smaller the least count, the more precise the measurement can be.

• It...read more

A machine is a device that uses energy to perform a specific task. There are various types of machines.

• Machines are designed to make work easier and more efficient.

• They can be classified into simple machines, compound machines, and complex machines.

• Examples of simple machines include levers, pulleys, and inclined planes.

• Compound machines are made up of two or more simple machines working together, such as a wheelbarrow...read more

Force is a push or pull that can change the motion of an object. There are two types of force: contact and non-contact.

• Force is a vector quantity, meaning it has both magnitude and direction.

• Contact forces are those that require physical contact between two objects, such as friction and tension.

• Non-contact forces are those that act at a distance, such as gravity and electromagnetic forces.

• Force can be measured in units

Strain is the measure of deformation of a material due to an applied force. Dimension formula is the formula to calculate the dimensions of a physical quantity.

• Strain is the ratio of change in length to the original length of a material.

• It is denoted by the symbol 'ε'.

• The formula for strain is ε = ΔL/L, where ΔL is the change in length and L is the original length.

• Dimension formula is a formula used to calculate the di...read more

Thermodynamics laws describe the behavior of energy and its transformation in a system.

• Thermodynamics laws are fundamental principles that govern the behavior of energy in a system.

• The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

• The second law of thermodynamics states that the total entropy of a closed system always increases over time.

• The thi...read more
