Sheet metal parts are not typically the final product but are one of many components making up a larger assembly.
Factors affecting tolerances include material thickness machines used and number of steps in part production.
In the ideal.
Sheet metal design guidelines are followed to design quality sheet metal enclosures.
Interviewers can ask questions on sheet metal design guidelines materials manufacturing process and finish operations.
Therefore exceptions can be there for complex features design.
This helps in delivering the product at low cost and faster timelines.
Many engineers developing 3d models for sheet metal products are unaware of the fabrication tools used to form the part or product and instead design models for an ideal world.
Following all sheet metal design guidelines is very difficult in the complex part.
Customer teams are often surprised to learn how sheet metal can make or break their supply chain and they come to realize the value of a professional sheet metal partner.

Successful sheet metal forming operation depends on the selection of a material with adequate formability appropriate tooling and design of part the surface condition of the sheet material proper lubricants and the process conditions such as the speed of the forming operation forces to be applied etc.
All other factors influencing sheet metal forming we should recall that a sheet metal forming operation can always be from the conceptual point of view.
A press brake creates a bend by pressing sheet metal into a die with a linear punch so design does not allow the creation of closed geometry.
For a design engineer position.
