10+ Paytm Interview Questions and Answers

Measurement System Analysis is a method used to assess the measurement system's capability to provide accurate and reliable data.

• It helps in identifying sources of variation in the measurement process.

• Common methods include Gage R&R (Repeatability and Reproducibility) studies.

• The goal is to ensure that the measurement system is reliable and capable of producing consistent results.

• It involves evaluating factors such as accuracy, precision, bias, linearity, stability, and repea...read more

Statistical process control (SPC) is a method of quality control which uses statistical methods to monitor and control a process.

• SPC involves collecting and analyzing data to monitor the stability and performance of a process.

• It helps identify variations in a process that could lead to defects or errors.

• Common tools used in SPC include control charts, histograms, and Pareto charts.

• By using SPC, organizations can make data-driven decisions to improve process efficiency and qua...read more

There are many types of bearings, but two common types are ball bearings and roller bearings.

• Ball bearings use balls to reduce friction and support radial and axial loads.

• Roller bearings use cylindrical or tapered rollers to reduce friction and support heavier loads.

• Ball bearings are typically used in applications with lighter loads and higher speeds, such as in electric motors.

• Roller bearings are commonly used in applications with heavier loads and lower speeds, such as in a...read more

Qualification refers to the process of assessing whether an individual or entity meets certain requirements or standards.

• Qualification involves evaluating skills, knowledge, experience, and credentials.

• It is used to determine if someone is suitable for a particular job or task.

• Examples include educational qualifications, professional certifications, and job experience.

• Qualification can also refer to the process of certifying products or services meet certain standards.

An address name is a unique identifier for a specific location, typically consisting of a street name and number.

• Address name helps in accurately identifying and locating a place.

• It is used for mailing purposes and navigation.

• Examples: 123 Main Street, 456 Elm Avenue, etc.

G codes are used to control the movement of the machine while M codes are used to control machine functions.

• G codes are used for positioning and feed rate control.

• M codes are used for machine functions like turning on/off coolant or spindle.

• G codes are modal and remain in effect until changed, while M codes are non-modal and only active for one block of code.

• Example: G01 is a G code for linear interpolation, M03 is an M code for spindle on clockwise rotation.

Force is a physical quantity that can change the motion of an object. Newton's laws describe the relationship between force and motion.

• Force is measured in Newtons (N)

• Newton's first law states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force

• Newton's second law states that the acceleration of an object is directly proportional to the force applied to it and inversely proport...read more

Least count is the smallest measurement that can be read on a measuring instrument.

• Least count of a micrometer is 0.01 mm

• Least count of a vernier caliper is 0.02 mm

• Both instruments are used for precise measurements in engineering and manufacturing

• The least count is important for accurate readings and calculations
