Deepjyoti India Foundation Interview Questions and Answers

Tolerance is the acceptable range of variation in a measurement or quality, used to ensure products meet specifications.

• Tolerance is the allowable deviation from a standard or specification in dimensions, performance, or other characteristics.

• It is used to ensure that products meet quality standards and function properly.

• Tolerance helps prevent defects and ensures consistency in manufacturing processes.

• Examples include tolerance for dimensions in engineering drawings, toleran...read more

The least count of a vernier caliper is the smallest measurement that can be read or measured using the instrument.

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

• It is determined by the number of divisions on the main scale and the vernier scale.

• For example, if the main scale has 20 divisions and the vernier scale has 10 divisions, the least count would be 0.02 mm.

7 quality control is a set of principles and techniques used to ensure products meet quality standards.

• 7 quality control involves inspecting, testing, and sampling products to ensure they meet specifications

• It also includes identifying and addressing defects or deviations from quality standards

• Quality control helps to prevent defects, improve processes, and increase customer satisfaction

Daily gauge and micrometer have different least counts for measuring precision.

• Daily gauge typically has a least count of 0.01 mm for measuring small dimensions accurately

• Micrometer usually has a least count of 0.001 mm for more precise measurements

• Least count refers to the smallest measurement that can be read on the scale of the instrument

Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through heating and cooling.

• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The process can be used to increase the hardness, strength, toughness, and ductility of a material.

• Common heat treatment processes include annealing, tempering, quenching, and c...read more
