JMA Wireless Interview Questions, Process, and Tips

GD&T stands for Geometric Dimensioning and Tolerancing, a system for defining and communicating engineering tolerances.

• GD&T is a symbolic language used on engineering drawings to specify the allowable variation in form, size, and orientation of features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T includes symbols such as concentricity, flatness, perpendicularity, and position.

• It is co...read more

Types of fits and tolerances refer to the relationship between mating parts in terms of the tightness or looseness of their fit.

• There are three main types of fits: clearance fit, interference fit, and transition fit.

• Clearance fit allows for clearance between the mating parts, ensuring easy assembly and disassembly.

• Interference fit results in a tight connection between the parts, often requiring force to assemble.

• Transi...read more

Sheet metal manufacturing process involves cutting, bending, and assembling metal sheets to create various products.

• Cutting: Sheets are cut into desired shapes using tools like shears, lasers, or plasma cutters.

• Bending: Sheets are bent into specific angles using press brakes or rollers.

• Assembling: Cut and bent sheets are assembled together using welding, riveting, or adhesive bonding.

• Finishing: Final finishing touches ...read more

Ansys software is used for thermal, structural, and modal simulations in mechanical engineering.

• Ansys is a powerful simulation software used for analyzing thermal behavior, structural integrity, and modal characteristics of mechanical systems.

• Thermal simulations in Ansys help in predicting temperature distribution, heat transfer, and thermal stresses in components.

• Structural simulations in Ansys analyze the mechanical ...read more

Static simulation analyzes the behavior of a system under steady-state conditions, while transient simulation looks at how a system responds to changes over time.

• Static simulation involves solving for equilibrium conditions, such as stress and deformation in a structure.

• Transient simulation involves analyzing dynamic events, like impact or vibration, and how they affect the system over time.

• Both types of simulations re...read more
