Sansera Engineering Interview Questions, Process, and Tips

Carbide formation after carburizing can lead to brittleness and reduced strength. Proper heat treatment and tempering can help prevent this issue.

• Perform proper heat treatment and tempering to prevent carbide formation

• Adjust carburizing parameters to avoid excessive carbon diffusion

• Use a different carburizing method, such as gas carburizing instead of pack carburizing

• Consider using a different material with better resi...read more

Reference air is a gas used as a reference point for measuring gas concentrations, while purged air is used to remove contaminants from a system.

• Reference air is typically a gas with a known and stable concentration of a particular substance, used as a baseline for comparison with other gases.

• Purged air is used to remove contaminants from a system or environment, such as in a laboratory or industrial setting.

• Purged air...read more

Carbide, Ferrite and RA are different types of materials used in engineering.

• Carbide is a compound of carbon and a metal, commonly used in cutting tools.

• Ferrite is a magnetic iron compound, used in electrical components.

• RA stands for 'roughness average' and is a measure of surface roughness.

• Carbide and Ferrite are materials, while RA is a measurement.

• Each material has unique properties and uses in engineering applicati

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint.

• Brazing uses a filler metal with a lower melting point than the base metals being joined.

• The filler metal is heated to its melting point and then flows into the joint by capillary action.

• Brazing is commonly used in HVAC, automotive, and aerospace industries.

• Brazing can be done wit...read more

G codes & M codes are commands used in CNC machines to control their movements and functions.

• G codes control the movement of the machine, such as its speed, direction, and position.

• M codes control the machine's auxiliary functions, such as coolant, spindle rotation, and tool changes.

• Examples of G codes include G00 for rapid positioning, G01 for linear interpolation, and G02/G03 for circular interpolation.

• Examples of M ...read more

BOM stands for Bill of Materials and Routing refers to the sequence of operations required to manufacture a product.

• BOM is a list of all the raw materials, sub-assemblies, and parts needed to manufacture a product

• Routing defines the order in which the operations are performed to manufacture a product

• BOM and routing are essential components of manufacturing and production planning

• BOM and routing help in determining the ...read more
