10+ Wipro Interview Questions and Answers

To create process planning for an assembly, I would analyze the assembly process and break it down into individual steps.

• Identify the components and their specifications

• Determine the sequence of assembly steps

• Identify the tools and equipment required for each step

• Determine the time required for each step

• Create a detailed process plan document

• Continuously review and improve the process plan

Torque value selection criteria depend on the application and the fastener being used.

• The material and size of the fastener

• The material and thickness of the joint being fastened

• The required clamping force

• The type of tool being used

• The desired level of torque accuracy

• The environmental conditions

• The torque specifications provided by the manufacturer

• The torque testing and calibration equipment available

Lifting tools used in assembly line include cranes, hoists, lifts, and jacks.

• Cranes are used for heavy lifting and moving large components.

• Hoists are used for lifting and moving smaller components.

• Lifts are used for raising and lowering workers to different levels.

• Jacks are used for lifting and supporting vehicles or equipment.

• Other lifting tools may include slings, chains, and hooks.

PPE in assembly line include safety glasses, gloves, earplugs, hard hats, and steel-toed shoes.

• Safety glasses to protect eyes from debris and chemicals

• Gloves to protect hands from cuts and chemicals

• Earplugs to protect ears from loud noises

• Hard hats to protect head from falling objects

• Steel-toed shoes to protect feet from heavy objects

A Manufacturing Bill of Material (MBOM) is a comprehensive list of all the components, sub-assemblies, and raw materials needed to manufacture a product.

• MBOM is used to plan and manage the production process

• It includes information on the quantity, cost, and lead time of each component

• MBOM is often created using a Product Lifecycle Management (PLM) software

• It helps ensure that all necessary components are available when needed

• MBOM is an essential tool for efficient and cost-ef...read more

SOE is a documented sequence of steps or events that must occur in a specific order to complete a task or process.

• SOE is used in manufacturing to ensure consistency and quality in production.

• It outlines the specific steps and order of operations required to complete a task or process.

• SOE can be used for assembly, testing, packaging, and other manufacturing processes.

• Examples of SOE include assembly instructions for a product, a recipe for a food item, or a checklist for a mai...read more

RPN in PFMEA is calculated by multiplying Severity, Occurrence, and Detection scores.

• Assign a score of 1-10 for Severity, Occurrence, and Detection.

• Multiply the three scores to get the RPN (Risk Priority Number).

• Identify the highest RPNs and prioritize actions to reduce them.

• RPN = Severity x Occurrence x Detection.

• Use a scale to determine the score for each factor, such as the one provided by AIAG.

• Update the PFMEA with new RPNs after implementing corrective actions.

Assembly sequencing involves determining the order in which parts are assembled to create a final product.

• Identify the components and their dependencies

• Determine the optimal order of assembly

• Consider factors such as safety, efficiency, and quality control

• Create a detailed assembly plan and communicate it to the team

• Continuously evaluate and improve the assembly process

Torque audit is a process of verifying the accuracy of torque applied to fasteners during assembly.

• It involves using a torque wrench to measure the torque applied to each fastener.

• The measured torque is compared to the specified torque in the assembly instructions.

• Any discrepancies are noted and corrected to ensure proper assembly and prevent failures.

• Torque audit is commonly used in automotive and aerospace industries.

• It is an important quality control measure to ensure prod...read more
