Fujitsu Interview Questions and Answers

Machining operations involve using various tools and techniques to shape and cut raw materials into the desired shape and size.

• The job may involve using lathes, milling machines, grinders, or other specialized equipment.

• The machinist must carefully measure and mark the material before cutting or shaping it.

• The machinist may need to use different cutting tools or techniques depending on the material being worked on.

• Examples of machining operations include drilling holes, turni...read more

The K factor is a value used in sheet metal design to determine the amount of springback that occurs during bending.

• The K factor is a ratio that relates the neutral axis to the material thickness.

• It is used to calculate the bend allowance and bend deduction in sheet metal bending operations.

• A higher K factor indicates more springback, while a lower K factor indicates less springback.

• Different materials and bending processes have different K factor values.

• For example, the K fa...read more

Spring back effect is the tendency of a material to return to its original shape after being deformed.

• Spring back effect occurs when a material is bent or stretched and then released, causing it to return to its original shape.

• It is commonly observed in materials like metals and polymers.

• The amount of spring back depends on the material's elasticity and the magnitude of the deformation.

• Spring back can be a desirable or undesirable effect depending on the application. For exam...read more

Gear ratio is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear.

• Gear ratio determines the speed and torque relationship between two gears.

• It is calculated by dividing the number of teeth on the driving gear by the number of teeth on the driven gear.

• A gear ratio greater than 1 indicates a reduction in speed and an increase in torque, while a ratio less than 1 indicates an increase in speed and a decrease in torque.

• For example, if a ...read more

The symbol of first angle method is a triangle with the vertex pointing downwards. The symbol of third angle method is a triangle with the vertex pointing upwards.

• First angle method is commonly used in Europe and Asia while third angle method is commonly used in North America.

• In first angle method, the object is placed in the first quadrant while in third angle method, the object is placed in the third quadrant.

• The symbol is usually placed in the lower right corner of the dra...read more
