TVS Sundram Fasteners Tool & DIE Maker Interview Questions and Answers

Wrinkles occur due to excessive stress on the material during the forming process.

• Wrinkles are caused by compressive stresses in the material.

• They occur when the material is stretched or bent too much in a localized area.

• Factors that contribute to wrinkles include material thickness, bend radius, and lubrication.

• Wrinkles can be prevented by adjusting the forming process parameters or using a different material.

• Examples...read more

Crack problems in tool and die making can occur due to various reasons.

• Cracks can occur due to improper heat treatment of the material.

• Excessive stress on the tool can also lead to cracks.

• Improper design or manufacturing process can also be a cause.

• Cracks can also occur due to wear and tear over time.

• Regular maintenance and inspection can help prevent crack problems.

Dent mark problems occur due to various reasons such as improper handling, tool wear, and material defects.

• Improper handling of the tool or material can cause dent marks.

• Tool wear can also lead to dent marks on the material.

• Material defects such as impurities or inconsistencies can result in dent marks.

• Dent marks can also occur due to incorrect tool selection or setup.

• Proper maintenance and inspection of tools can help

Tolerance is the allowable variation in a dimension. There are two types of tolerance: unilateral and bilateral.

• Tolerance is the difference between the maximum and minimum limits of a dimension that is acceptable.

• Unilateral tolerance allows variation in only one direction, while bilateral tolerance allows variation in both directions.

• Tolerance is important in manufacturing to ensure that parts fit together properly and...read more

An ejector is a device used to create a vacuum by converting pressure energy into velocity energy.

• Ejectors are commonly used in industries such as chemical, petrochemical, and power plants.

• They work on the principle of the Venturi effect, where a high-pressure fluid is converted into a high-velocity stream through a constricted section.

• Ejectors are used for tasks such as pumping liquids, creating a vacuum, or mixing fl...read more

A slider is a mechanical component that moves along a linear path.

• Slider is commonly used in machinery and equipment to provide linear motion.

• It typically consists of a sliding block or carriage that moves along a rail or track.

• Examples include drawer slides, camera sliders, and linear actuators.

Tool maintenance process involves regular inspection, cleaning, lubrication, and repair of tools to ensure they function properly and have a longer lifespan.

• Regularly inspect tools for wear and damage

• Clean tools after each use to prevent buildup of debris

• Lubricate moving parts to reduce friction and wear

• Store tools properly in a dry and secure location

• Repair or replace damaged parts as needed

• Keep a maintenance log to t

Types of tools include hand tools, power tools, cutting tools, measuring tools, and fastening tools.

• Hand tools: Screwdrivers, hammers, wrenches

• Power tools: Drills, saws, sanders

• Cutting tools: Knives, scissors, shears

• Measuring tools: Tape measures, rulers, calipers

• Fastening tools: Nail guns, staple guns, screws

The thickness of the part is 2.5 millimeters.

• The thickness of the part is a critical dimension that needs to be accurately measured.

• It is important to ensure that the part meets the required thickness specifications.

• Examples of tools used to measure thickness include calipers, micrometers, and thickness gauges.

Vernier is a measuring instrument used for more precise measurements than a regular scale or ruler.

• Vernier is used to measure small distances with high accuracy.

• It consists of a main scale and a sliding vernier scale that allows for more precise readings.

• Vernier calipers are a common type of vernier used in engineering and machining.

• Vernier is commonly used in tool rooms for accurate measurements of tools and component

PM of mold involves regular inspection, cleaning, lubrication, and replacement of parts to ensure optimal performance.

• Inspect mold for wear and damage

• Clean mold surfaces regularly to prevent buildup of debris

• Lubricate moving parts to reduce friction and wear

• Replace worn or damaged parts as needed to maintain quality of output

• Keep detailed records of maintenance activities for future reference

History card can be checked by reviewing the documented information related to a particular tool or equipment.

• Review the history card for details on maintenance, repairs, inspections, and usage of the tool or equipment.

• Check for dates of previous maintenance activities and any issues reported during inspections.

• Verify that all required information is properly documented on the history card.

• Ensure that the history card ...read more
