Saras 3D Mechanical Engineer Interview Questions and Answers

Limits fits and tolerances are used in engineering to determine the acceptable range of dimensions for mating parts.

• Limits are the maximum and minimum acceptable dimensions for a part

• Fits are the range of tightness or looseness between mating parts

• Tolerances are the allowable deviation from a specified dimension

• Examples: H7/g6, H8/f7, etc.

Tolerance in shaft and hole is achieved by specifying the acceptable range of dimensions for both components.

• Specify the desired fit (clearance, interference, transition) between the shaft and hole

• Determine the basic size of the shaft and hole

• Select the tolerance class based on the required precision

• Apply the appropriate geometric tolerances if needed

• Consider factors like material properties, manufacturing processes, a...read more

Steps to create a 3D model of a Steering wheel in CAD software.

• Start by creating a new file in the CAD software.

• Sketch the basic shape of the steering wheel using tools like lines, arcs, and circles.

• Extrude the sketch to give it depth and create a 3D shape.

• Add details such as grips, buttons, and logos using additional sketches and features.

• Apply materials and textures to make the model realistic.

• Check for any errors or...read more
