Desai Engineering Works Tool Design Trainee Interview Questions, Process, and Tips

Software commonly used in Tool Design include CAD software like AutoCAD, SolidWorks, and CATIA.

• AutoCAD is widely used for 2D drafting and design

• SolidWorks is popular for 3D modeling and simulation

• CATIA is often used in aerospace and automotive industries

Bending tool plates are typically made of materials like tool steel, aluminum, or composite materials.

• Common materials used for bending tool plates include tool steel, aluminum, and composite materials.

• Tool steel plates are preferred for their durability and resistance to wear during the bending process.

• Aluminum plates are lightweight and can be used for bending softer materials.

• Composite materials offer a balance of s...read more

To calculate actual size folding and total length in part design, use formulas based on material thickness and bend angle.

• For calculating actual size folding, use the formula: Actual Size = Material Thickness x Tan(Bend Angle)

• For calculating total length, use the formula: Total Length = (2 x Bend Allowance) + (π x Inside Radius x Bend Angle/180)

• Ensure to convert the bend angle from degrees to radians when using trigono...read more

Press tools are used to perform operations such as cutting, bending, punching, and forming on sheet metal.

• Cutting operations to cut the sheet metal into desired shapes

• Bending operations to bend the sheet metal at specific angles

• Punching operations to create holes or indentations in the sheet metal

• Forming operations to shape the sheet metal into complex geometries

• Examples: blanking, piercing, embossing, coining

Bridge and Margin Size in Striplayout Calculation determine the spacing between pieces and the edge distance, while Pitch and Number of Pieces cut determine the length of sheet required.

• Bridge Size is the distance between two adjacent pieces on a sheet

• Margin Size is the distance between the edge of the sheet and the first piece

• Pitch is the distance between the same points on two consecutive pieces

• Number of Pieces cut d...read more
