Paytm Payments Bank Interview Questions and Answers

Cylindricity refers to the overall 3D form of a cylinder, while roundness refers to the deviation of a circle from a perfect circle.

• Cylindricity is a 3D tolerance that controls the overall form of a cylinder, ensuring that all points on the surface lie within a specified tolerance zone.

• Roundness is a 2D tolerance that controls the deviation of a circle from a perfect circle, ensuring that the entire circle lies within a specified tolerance zone.

• Cylindricity is used when the f...read more

A brake system works by converting kinetic energy into heat energy through friction to slow down or stop a vehicle.

• Brake pedal is pressed by the driver

• Brake fluid is compressed in the master cylinder

• Pressure is transmitted through brake lines to the brake calipers or wheel cylinders

• Brake pads or shoes press against the brake rotor or drum to create friction and slow down the vehicle

To create a 3D model from an engineering drawing, use CAD software to accurately replicate the dimensions and features.

• Use CAD software such as AutoCAD, SolidWorks, or Fusion 360 to create the 3D model.

• Refer to the engineering drawing for dimensions, angles, and features to accurately replicate in the 3D model.

• Utilize tools within the CAD software to create extrusions, cuts, fillets, and other features as needed.

• Check the 3D model against the engineering drawing to ensure acc...read more

Yes, I can create detailed 2D drawings based on the 3D model provided.

• Create orthographic views (top, front, side) of the 3D model

• Include dimensions, annotations, and tolerances in the drawings

• Generate section views to show internal features

• Add surface finish symbols and notes as needed

Stack up tolerance refers to the accumulation of tolerances in a series of components or parts that are assembled together.

• Stack up tolerance is important in ensuring that all components fit together properly in an assembly.

• It involves considering the individual tolerances of each component and how they may add up or cancel out when assembled.

• For example, if a shaft has a tolerance of +/- 0.1mm and a hole has a tolerance of +/- 0.2mm, the total stack up tolerance would be +/-...read more
