Voith Interview Questions and Answers

Theory of failure is a concept used in engineering to predict the failure of materials under different loading conditions.

• Theory of failure helps engineers understand how materials will behave under stress and strain.

• Different theories of failure include maximum normal stress theory, maximum shear stress theory, and maximum strain energy theory.

• Finite Element Method (FEM) is a numerical technique used to analyze stress...read more

The SS curve is a stress-strain curve used to analyze the behavior of a material under stress.

• The SS curve, also known as the stress-strain curve, shows the relationship between stress (force applied per unit area) and strain (deformation) of a material.

• It typically consists of three main regions: elastic deformation, plastic deformation, and fracture.

• The elastic region is where the material deforms elastically and ret...read more

To create a manufacturing drawing for a complex machined frame, precise measurements and specifications are required.

• Gather all necessary information about the frame's dimensions and specifications

• Create a detailed 2D or 3D model of the frame using CAD software

• Include all necessary annotations, dimensions, and tolerances in the drawing

• Specify the materials and finishes to be used

• Ensure that the drawing complies with in...read more

Balancing procedure for rotating equipment involves identifying unbalance, measuring vibration, and adding or removing weight to achieve balance.

• Identify unbalance by measuring vibration

• Determine the amount and location of unbalance

• Add or remove weight to achieve balance

• Repeat the process until vibration is within acceptable limits

• Use balancing equipment such as a balancing machine or portable balancer

• Examples include ...read more

The manufacturing procedure for a big welded and machined frame made of stainless steel involves several steps.

• Design the frame using CAD software

• Cut the stainless steel sheets into required sizes using plasma or laser cutting machines

• Weld the cut pieces together using TIG or MIG welding techniques

• Machine the welded frame to achieve the desired shape and dimensions using CNC machines

• Perform surface finishing operations...read more

SS cladding is done on MS frame to protect it from corrosion and increase its durability.

• The MS frame is first cleaned and prepared for cladding.

• The SS sheets are cut to size and welded onto the MS frame.

• The joints are then ground and polished to ensure a smooth finish.

• The cladding thickness and welding quality are checked to ensure compliance with standards.

• The final product is inspected for any defects or imperfectio...read more

Cantilevering procedure in wire section involves supporting a wire on one end while the other end is being worked on.

• The wire is clamped or held in place on one end

• The other end is then bent or cut to the desired shape

• Examples include creating hooks or loops on the end of a wire

• Cantilevering can also be used to create a spring-like effect in a wire

A tri nip press concept drawing for efficient material processing.

• Consider the size and shape of the material being processed

• Include three rollers with adjustable pressure

• Incorporate safety features such as emergency stop buttons

• Include a control panel for adjusting pressure and speed

• Consider the material of the rollers for durability

• Ensure the design allows for easy maintenance and cleaning
